In this episode, Ronnie and Wes describe and discuss the basic mobile device uses:  As a personal cell phone, a voice mail system, a SMS system and even a notification system. They describe the device must be connected with a service provider for the usage of these system.  Wes also describes the it’s functionality as a phone and shows some of the components to manually setup the device to use the voice mail and notification systems as well.  The guys also briefly tell us some of the most common vendors of the phone hardware.

[MUSIC] Welcome to another great episode right here on ITProTV. I'm your host, Ronnie Wong, and you are watching the IC3 Computing Fundamentals show where we are about to take a look at some mobile devices and talk about some of the different things that we need to understand there. And who better to help us than Mr. Wes Bryan. Wes, welcome to our show. >> Thank you, sir, it's good to be here as always with ITProTV. And that's right, we're gonna be looking at mobile devices today. And we're gonna talk a little bit about well, what is more importantly a cell phone. Cuz there's many different mobile devices and we'll talk about some of those device types in a later episode. But for us today, what we're gonna be focusing in on really is the concept of the cell phone. And how long have the cell phones been around? Well, they've been around since, I wanna say, like the late 70s or the early 80s was the first time somebody made a call over the air through radiated energy and wasn't plugged in, if you will, to the wall. I joke around with people and I tell them I had a cell phone once and I got it all the way to Georgia until the cord came out of the wall. But all joking aside, we're gonna look at the mobile phone here, and when it comes down to a mobile phone, what are we talking about? Well, we're talking about a device that, first, like the name implies is the mobility. The ability to move this device and not be locked into the traditional land lines. Now they are more and more prevalent today, and maybe you've heard of this term and maybe you haven't, BYOD, bring your own device. They are in the home environment, they are in the enterprise environment and we're having many millions of them as we speak are probably being made right now. So looking at a mobile phone, let's talk about how I would get a mobile phone before I even start to use it? Well, mobile phones you typically go to a vendor or provider and you purchase them. Now these are subscription based devices in which you have to have a subscription in order to use them. It's not like a desktop. Right, if I purchase, let's say go to a vendor and I purchase a desktop, I bring it home. Well, guess what, I don't need to talk really to any kind of subscription provider in order to use that desktop. On the other hand, if I have a mobile phone, if I don't talk to a subscription provider and pay a monthly fee, the mobile phone's really gonna be useless for us in that aspect. So let go ahead, let's dive right in. I've actually got a mobile phone pulled up here on my computer, right. And with these mobile phones today, they definitely differ a lot than they did in the early days. With these mobile phones today, these are really, when it comes down to it, these are small computers. These are very, very powerful devices and they allow us a lot of functionality. And what we really wanna look at is, just some of the basics on how you would use a cellphone to begin with. We're gonna look at some of the settings and then we'll gonna talk a little bit about how you would use one to dial out and make a call. All right, so this is the interface and there's a couple of different types of phones. This is by far, when we talk about the input and working with the phone, it's one of the more common ones. You can't really see it right here, it's kinda off camera here. But this is a touch screen interface. And you can see on my computer screen where I'm actually inputting, touching the screen if you will. Now the other type that we have is one that's been around for a while as well and that's the one that has more of the tactile push button. They're still out there, they're very prevalent but the most common one today are the touch interfaces. And they're typically today called smartphones versus another term that maybe you have or haven't heard called the dumbphone, right. The older phones back in the 90s and even the mid 2000s with Blackberry and stuff and again they have the tactile keyboard and sometimes you could use a stylus. When you look at these smartphones today, again, primarily what we have is the touch interface as the means of working with the phone itself. Let's go ahead and look at some of the settings that you could configure in your cell phone so you'll be a little bit more aware of how to use it. Now understand that what we're on right now is a Windows mobile phone. Some of the major mobile phones that you have, really the big three, if you will, and I say big really big two, as Ronnie and I were talking about it prior to coming on stage here, is that we have, well, we have the iPhone. The iPhone definitely is one that kind of revolutionized the entire cellphone industry, being one of the first that really provided that fluid, thorough touch interface. The other one being the Samsung based devices, and this is Android. Not Samsung, excuse me, I'm thinking of my phone. >> Android based. >> Yeah, the Android devices. Now when we look at something like an iPhone or we look at something like an Android, they're definitely two completely different markets even though we're talking about cellphones. When we look at iPhone, iPhone is what's known as a close source proprietary phone in which the operating system that runs on it is controlled by Apple and the hardware itself is controlled by Apple likewise as well. Now with the Android devices, this is a little bit different. They have many different devices that an Android phone operating system more specifically will run on. And you have many different vendors out there, Samsung being one of the ones that I think about cuz that's the cell phone that I have. Android is an open source platform. And there's a little bit of a major difference here. When we say proprietary, what does that mean? Well, when we talk about proprietary, what we mean is that, again, one company basically controls all the code. They don't release it to the public, it's maintained in-house, internally. And if, let's say, if Ronnie was to get a piece of that code and say, hey, let me go ahead and do some designing on that and maybe try to put that on a phone that maybe he's working on, well, the company that owns that software, that proprietary software, they could end up suing him for everything that he's worth, right? Well, that's what the iOS, the operating system that runs on the iPhone is, it's closed source and even the hardware behind it, Apple controls it. Now you look at something like Android, when we say open source, we say non-proprietary. All right, what this means is that, and I'm pretty sure when it came to Android, it started out with something known as the Open Handset Alliance that started this operating system based on the Linux kernel, and Google comes along and they say well, we really like this, we wanna go ahead, and they purchased the company. Now today it's considered Google's platform, if you will. But it is still open source in the fact that the code that the operating system, right, what allows us to even use the cellphone, it's freely downloadable. You can make contributions to it, and there's a lot of variance out there as well. But one of the great things about that is the fact that if you decide to make changes or modifications to the operating system you're really not gonna be charged. So I wanna kinda set the stage for what cellphones you might see out there and then some of the operating systems. So with that being said, the other one is maybe not quite as popular as the first two. Those first two are definitely the most popular. The third one there is the mobile phone. And the mobile phone, or the Windows, excuse Windows mobile phone, and this has got different variants, different flavors of the operating system. And this is also a closed source operating system in which Microsoft basically maintains the operating system and they have a limited amount of hardware that it supports. But we're gonna go ahead and look at that a little bit more. So let's go ahead, let's dive back in. We're gonna look at some of the settings, and we'll talk about some of the different settings that are on phones that are common to all of them regardless of the phone and the operating system that you have. So I'm gonna go ahead and I'm gonna drill down in here to Settings. And a lot of times what you have, one of the first things that you might wanna be able to figure out is, how to, well, let's just say maybe send an email, maybe send a text message. But more than all, you're gonna wanna be able to, well, use the cellphone to call somebody, right? We talk about a smartphone and the fact that it's a computer that can do multiple things. But we also wanna look at the basics too. How do you even make a phone call? And with this one here, you can see that there's a little bit of a phone icon, they call it a tile, here in this interface. And If I needed to make a call, I could do it. And you can see in this operating system here, it tells me that we can do things like speed dialing, right? And then history as well is there. So if I've made calls, if Ronnie's called me and I happen to miss a call. Well, it'd be nice to know who it is that called me and have some kind of a reminder that hey, you missed a call. Well we could see that in the history as well as the people that maybe we call ourselves. And then there's a button down here at the bottom. You have a series of buttons here. You can see that this one, the one all the way to the left, that's your voicemail. Let me get back in there, sorry guys. That's your voicemail. We'll talk a little bit about that coming up. And then you have your keypad, and the keypad really brings up the numerical keypad and this would allow you to enter the text if you will. If you wanted to you could, for instance, dial a phone number here and you could call in, something like that, right? And then all I have to do is I could just choose call and, provided we have our subscription paid, we can make a call to the other end, all right? Now that being said, fairly straight forward when it comes to using a cell phone. It doesn't take much as far as dialing and making a call. Again, voicemail is something else that we have. But the really cool thing is, we also have this other icon down here and this is your contacts icon, right? Your contacts icon can bring you right into what, if you can think back to the old, for instance, the old Rolodex, I know many people probably don't know what a Rolodex is anymore. When you had contacts you would write them down, you'd have a little book you would write down all your contacts, and then if I need to call Ronnie and I don't know what his number is, I could look into that little paper file. Well, obviously we're not going to carry those around, so it makes it convenient in the fact that we can have our contacts right here. And if we need to dial those contacts, we can, all right? Now we also have the search functionality, right? And the search functionality gives me a little bit easier way, in this case, to just search through those contacts without actually having to scroll through. All right, so fairly straight forward process when it comes to using the cell phone to make a phone call. However, there are other things that you might wanna be able or have the ability to do, so let's go ahead and continue through some of those settings. All right, now the first one I wanna talk about are the email and the accounts, all right? If you are going to allow your cell phone to receive and send email, you do have to set up your accounts. And whichever phone you have, it might differ a little bit, but essentially the steps should be pretty much the same. You have things like your Gmail accounts that are out there, Exchange accounts. Yahoo accounts, I don't know, maybe a AOL, I don't know if they still exist. But we could set those up if we wanted too. And you could see, I have a Microsoft account already attached to this. And if I wanted to, I could add an account. And you could see some of the options that we have, right? Exchange, if you have a business account, you could setup an Exchange account. If you, Outlook.com. They old Hotmail if some of you maybe guys know what the old Hotmail was. We could set that up and then there's also, and you could see the provider by the way. This third one down here, this is the actual provider of the phone. So when we talk about the subscriptions, I would have to pay AT&T a monthly subscription fee in order to well, basically use this phone for anything other than to dial out and send text messages. >> Now Wes, when we start taking a look at this, you're showing us the idea of the manual setup of things. And normally the reason why we have to use this a lot of times is if we're switching from one provider to another one. If I'm adding an additional email, it's kind of neat in the world of cellphones when we start taking a look at our mobile devices. And the very fact that if I get a brand new let's say Samsung S7, and it's straight from whoever I purchased it from, if they were actually my service provider as well, I really don't have to do a lot of the manual set up. It's not saying that what Wes is showing us is not valuable, but a lot of times it takes you through step-by-step when you first have it. So if this is your first introduction into the realm of actually getting a cell phone and go, I know I wanna get email, I know I need to set up my voice mail, I know I need to set up a bunch of different things here. It's neat, because it sends you through an initial setup wizard the first time. And, if you've already been using something like email, like I have a Gmail account. All I have to do is actually enter in my Gmail account and my password to that account, and then the rest of it, at least on Android devices, it knows how to connect all that stuff in, and it goes ahead and it sets up the email for me. It sets up my voice messaging, if I've got that service, for me. And it's not that those things aren't invaluable like I said. But a lot of times, for something like what Wes is showing us, if you now decided you wanted the Yahoo account on your phone as well, he's showing us where you actually go in there to add that Yahoo account. And then you'd have to get a bit more information. But just, so don't get overwhelmed by a lot of the stuff that you're seeing right here if this is your first time seeing it. Just kind of realize with just a couple of pieces of information, right Wes? Usually an email and a password, and a lot of the features that we can just talk about as far as basic phone usage. If we've got a service provider, it really does set itself up, right? >> It does, and that's one of the great things about it is just the fact that you have those introductory wizards if it's the first time that you've had the phone. The other thing being is, a lot of the times when you're purchasing a phone, you're going to have the person that's doing the sales, is pretty much going to set the phone up for you. But if you're supporting the phone, you are the sales person. How do you do that if you don't have a wizard? So you do have to keep in mind there is an automated approach, but you are troubleshooting a phone, I don't know how many times that Outlook has given me problems, right? Well, the problem is, one of the things I do have to keep in mind is I unfortunately don't get a wizard when it comes to troubleshooting what's going wrong with Outlook or this individual mail provider. Now the other thing that we have we're gonna look at a little bit too is some of the basics like a lock screen, right? Lock screen is very important when it comes to keeping your phone secure. It's not really advised to keep it unlocked. So let me go ahead and show you that real quick. Another one of the main settings here. If I choose the lock screen I can set things like, for instance, the background if I want. But more importantly, how long before the screen times out. And then a password too. That's important again for the protection of the phone. All right, now the other thing that we'll look at a little bit too is notifications. Notifications are important right? How intrusive the notifications are is really up to you. I know personally I try not to have too many notifications. However, my wife on the other hand she wants to know when anything goes on. So she's constantly getting bombarded by notifications, so we can also do that. We can choose notifications and again, keep in mind, that it might be a little bit different depending on what phone you have. For instance, I can see a quick scroll here, what are by quick actions here. I could say as far as my network connection, do I have blue tooth turned on? Do I not have it turned on, if you will, camera, and even the brightness settings. And it allows me a quick way to change these. I can also, again, if I want, I can change on how gadgets and different things. Messaging apps, banners, sound, vibrations on that. Maybe you're giving a presentation. In fact with myself right now, I've got my phone but it's muted. The volume's turned down because I don't want those notifications interrupting what we're doing right now. So also keep that in mind. An etiquette when it comes to your phones as well with notifications and making sure that if you're in a situation in which somebody's giving a presentation, you might wanna make sure that those notifications aren't too intrusive. [COUGH] Now, Wes when we start to look at the idea of just getting that phone to do some basic communications and I'm starting to set it up. There's really a couple of things that I remember really annoying me at the beginning. Which was I know that I needed to know how to actually dial a person's phone so that's kind of intuitive because I've been using phones pretty much my entire life. But the other one was actually a little bit more challenging which was to get access to my voicemail. When somebody said, yeah just set up your voicemail or check your voicemail. And so we want to talk about that notion for just a little bit of time. Wes, if somebody tells me and I've never setup my voicemail before, let's just talk about some of the primary things that most every provider actually give us. So if somebody said, Wes, I don't know how to setup my voicemail. What would you just tell them right then that they needed to do? >> Well, typically that's a great question. Typically, what we'll end up having is some kind of special number that you'll call in order to access your voicemail and, right out the gate when you first get your phone, chances are at best you have the most generic message if any at all. What do I mean by that? Well, if somebody calls you and you haven't set up your voicemail, you usually get one of two things. You get a this voice mail hasn't been set up for this phone number and well, it hangs up on you and nobody can send you a voicemail. The other is that it gives you a generic voice, I'll give you one that mine was set up and I didn't realize it when I first got my phone, is that it says the number you have called can't take calls right now. And it's very basic, simplistic voice there, and it said leave your message. All right, well, voice mail systems, voice messaging systems, they allow for the customizations, right? And one of the first things that you're gonna do is find out the vendor, how you access that voicemail system. For instance, mine in this case, for the provider that I have is, that on my phone, I type star 89 When I type star 89 it takes me right into a special account that is just for my voicemail. And then once I get there you typically have an automated process. If you've ever called somebody for support it says press one to do this, press two to do this, press star to hear more options. A lot of times that's what your voice mail systems are gonna do for all of the vendors. They're gonna say, to set up your inbox greeting, you're gonna set your message. That would be usually the first thing you'll do. And I'll say, hi, my name's Wes Bryan. You've reached my phone. I can't get to the phone right now. If you'd leave me your name and number and a small message, I'll get back with you. And then this way when people are calling in, that's the thing that they hear. Now, you also have things like your voice mailbox, might have just a basic greeting, right. It might say Wes Bryan, right. So sometimes when you call or when somebody calls you, and they get you're busy and you can't answer it. It says you've called the voice mailbox of, and then you'll hear my voice, Wes Bryan. Right, so, again it can be little more eccentric if you will, where you can, I always do this, I can never get the recording right, so I have to record it more than once, right. So that's one of the biggest things and the first thing you need to do is set up what the message is that people are gonna hear when they have an incoming call and you don't get to it. Now the other thing that you can typically do inside of your voicemail when it comes with messaging. The messages themselves, you can listen to the messages by pushing a certain key, you can save the message and depending on what the retention policy is for your local provider they'll say, well this message will be saved for 90 days and you don't have to worry about it being deleted. The other thing you can do is forward messages likewise, so don't be afraid if you've never set up a voicemail to get in there and try, right? Get in there and set it up and if you don't like what you've set up, that's one of the great things, it's not a one size fits all for sure. It can be customized. Each individual person might want a unique experience, and keep in mind that your voicemail message should be simplistic. I know some people want to make it a Martin Scorsese production but keep in mind it needs to be simple and to the point so that, I almost said end users. The people who are calling you don't hang up because you've got a five minute message and they have to wait forever to leave you that message. So that's one of the piece of advice I would give you is just keep it simplistic. The other thing that you might want to pay attention, is to how many messages you might be able to have. Some vendors limit the amount of messages that you have. So, you definitely want to be able to check them. And you definitely want to be able to manage them. Finally, what I'll say, just as a recap, is remember that every voicemail messaging system is unique. While they both follow the same basic pattern, setting up your voicemail incoming message and then some kind of numerical key that you have to punch, to push, to forward through the process. The only thing that is typically unique is the individual minutiaes if you will on the different flare functionality that they give you access to. >> Yeah Wes, when I first setup my voicemail on my phone, I didn't really know how to do it. I had to get some instructions, but one of the things that I did stumble upon that can really help you out if you can't find those directions, is to simply call the number that you have been given through your service provider for your phone. A lot of times that actually starts you off by saying, hey, I noticed something, you actually reached that phone number from the phone number that was assigned to that particular device, and then it asked you to go ahead and set up. Do you want the option set up for voicemail or do you want to do this? And then normally requires you to setup a PIN number and it requires you to leave at least one message so that now people can access it. And then from that point you can do what a lot of people do which is to just have that as one of your contacts and then when that way somebody does call you with a voicemail you just go ahead and name a voicemail and then you push that button, then it calls your number again, and you entering your PIN number to retrieve those codes, as well. So that's one of the features that are available to help us at least at the beginning, and we're not familiar with it. The other one though, is probably the feature that most people end up using with their phones, more often than anything else. And so Wes, people call this a lot of different things. Here in the states, we call it texting a lot of times. But technically this is called SMS? >> That's right, that's right. Now we're not gonna be short of acronyms in computer fundamentals and Ronnie's exactly right, SMS But I completely agree with Ronnie in the fact that most likely if you hear the term texting, that's really what's going on in the background. It's a system that's been around for a while. It's probably one of the most common messaging services we have. It allows you to send text based real quick text based entries. Sometimes there's a character limit on them. Like for instance my phone I just happen to look at this last night, has a 141 character limit. You can attach things like pictures if you want. You could do that as well. Primarily when it first started it was text based. It's definitely been advanced a lot since, I believe it was 83 when it first came out. Now, the other thing too that's great about SMS or text messages is that they integrate nicely with traditional telephony technologies, right. If you've never heard of the term, we're just talking about traditional phone lines, right. Is the fact that these messages can make their way over traditional phone lines in a lot of systems. So it really makes them very versatile in their application. Now when it comes to sending a text message, let me go ahead and show you guys. When you're sending a text message here, it's fairly easy. I've got this nice little thought bubble here and messaging there. Now that I've fumbled around for it a little bit here, we'll go ahead and look at the text messaging here. So, you can see the little plus symbol right down here and this plus symbol would allow me to start typing a text and what I would do is I would put the contact here and whoever the contact might be and then I could start typing the text message. I could do something like This Is my text or test, if you will. And then what that allows me to do, is once I put the contact in there, if I just go ahead and push send, it'll send that text message only. Right, it's not a phone call so we're not communicating with them other than through a text based method, if you will. Now, remember one of the things that I said that you could do here is that you could send an attachment. If I wanted to, I could also add a picture, add a video. Now, I want you to keep in mind something though. If you're not familiar with these data plans, remember you start sending these text messages and a lot of times, depending on your subscription, right, you could get text message for really cheap today. But, if you start adding video, if you start adding attachments through this, it's gonna chew through your data plan and it's gonna cost you more money. So just keep that in mind that this is a great way to send a quick, fast message to somebody. It's relatively inexpensive, but as you start adding attachments, you could start adding a little bit more value, or charge, if you will, to your regular SMS-based text messages. So very basic here. And at this point, once I was done all I would have to do is just click Send, and it would send that text message, let's say in this case, to Ronnie. And then if I dialed the number right or used the contact, I got the right contact information, Ronnie's gonna end up receiving that text message. >> Yeah, the neat thing or the nice thing then about the idea of using text messages is that not only can we do that one to one communication just like a regular telephone call, but let's say that Wes wanted a group of us to go and meet for lunch. Well in theory if we were just doing this on a telephone call, Wes would call me, and then call somebody else, and then call somebody else, and then call somebody else, let's say four or five different phone calls to do so. With the text messaging system though, if he knows what my phone number is, he can actually add in all of our phone numbers and just say, hey let's go and meet for pizza for lunch today and then send that and it sends it to all of those people in who the destination is for. And this way even if I'm in the middle of working, I will get that message without having to pick up the phone and so will everybody else. And then we can respond individually and that will also forward it on to everybody in that group as well. Normally when you start doing that. So the idea of messaging, this seems to kind of, almost, at least here in the United States to be one of the most predominant reasons why we end up using the phone is the ability to get these quick messages that we need to to the people that we need to. And a lot of time it's taken even over really the social side of things where you do walk into restaurants today and you see people sitting at the same table and they're actually either texting other people or even each other as they're actually sitting right across from each other. So you do have some of that that tends to go on there. But remember that the primary idea here behind that cell phone is the idea here of being able to communicate and establish that communication that we need. And we do have different methods that are out there, it goes from the very most basic thing which is simply to have a telephone call. And voice mail just like we used to have answering machines by our phones, now we can actually carry that with us regardless of where we are on this planet as well. And then of course you even have fancy ones, which Wes was actually mentioning and even showed us here, in that model of that Windows phone for us. And because we have barely scratched the surface on that Windows phone technology, just by talking about the idea the phone, and of course the text messaging and even the voicemail type setup and even a basic notification on things as well. So there is a lot of features that are actually in here with us Wes, is there anything we need to know about just the basics of the mobile device that we've been talking about? >> No, I would say just subscription. Subscription is the important thing, keep in mind that the features and functionalities that you have is really based on the provider that you're gonna use as your carrier. So Like Ronnie said we've already, we've talked about some of the basics. Keep in mind that you will just tailor make these, or tweak them a little bit just to suit whatever the provider is that you have. >> All right Wes, well thank you again for helping us to understand at least the basics of these mobile devices. There's a lot more for us to actually think about when it comes down to computing fundamentals. But at least you are getting a start here on these mobile devices if you haven't encountered them before. And it is a great place for us to end this episode as we also move on to new and other episodes that we are going to be doing. So, signing off for ITProTV, I have been your host Ronnie Wong. >> And I'm Wes Bryan. Stay tuned right here for more IC3 Computing Fundamentals. [SOUND]
