Cell Phones

A cellular phone (also known as a mobile phone, cell phone, hand phone, or simply a phone) is a telephone that can make and receive telephone calls over a radio link while moving around a wide geographic area by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. Mobile phones that offer services such as text messaging, email, Internet access, business applications, gaming, photography and more general computing capabilities are referred to as smartphones.

Hello Community Members...

I have several mobile devices ONE is a 10.1" screen with SIM enabled (Like an iPad lol) so can get net on SIM

Now this is UNLIMITED data

If I played / streamed music on My mobile phone would have to use hotspot which the 10.1" provides RIGHT

But would use My allowance of hotspot

If played music from the "SIM enabled device" and hot spotted the mobile phone for data

Would that be UNLIMITED DATA from the 10.1" BUT keep within My hotspot limit for My mobile phone


Both mobile devices using the hotspot allowance ??

All help VALUED with My current question

Is it possible to share iTunes Library between PC & Android phone?

A brief search yielded shows information about using Android but I don't see any literature on using Android phones other than Apple Music subscriptions.

Is this a recent change or has it always taken an Apple mobile device to play your library from a mobile device?
I am creating an Android application that allows users to add notes, organize them into categories, and set reminders for the notes in the form of push notifications.

I am able to schedule reminder notifications when the phone is on. However, if you turn the phone off and then turn it on later, or restart it, then set multiple notifications: one that has a scheduled time after the phone has been rebooted or turned on again and one that is scheduled to go off at a time after the phone has been rebooted or turned off, then both notifications go off immediately after the phone turns on or is rebooted.

The expected behavior is that the notification that is scheduled at a time after the phone has rebooted fires at the scheduled time instead of right away.

Please see RebootReceiver.java and NotificationScheduler.java below and let me know if you need additional files from my project or information.

Which cellular carrier has the best coverage?
There's a lot of marketing that says Verizon is the best.  But is it really?
And how about the super-cheap cellular services.  Which carrier are they using.  Surely the smaller brands don't have their own network backbone.

Another wierd observation!  Some people are able to surf the net on their smartphones in the NYC subways, others can't!  The transit authority WiFi ain't that good.  So, its gotta be the cellular carrier.
I appreciate links to useful studies, articles, or videos.
What are the best mounts for mounting an iPhone X to my car's dashboard so that I can follow my iPhone X's GPS navigation?

This must be a dashboard mount that I can easily move between cars since I drive several different cars. I also want it to be easy to detach and reattach my iPhone X to such a mount since I take my iPhone X with me wherever I go. I am looking for a mount that I can put on top of my dashboard and not one that attaches to the air vents, etc.

Let me know what the best mounts are that I can buy online or through Amazon.
Have a Samsung S9+ Android Phone that I purchased and am very pleased with. It's the first Android phone I've ever owned and I think it craps all over all of the iPhone's I've used for many years :)

There are three things I'd like to get for it though and not sure what and where to purchase these items online.

1)  A decent phone holder to use in my car so I can use it hands-free. I just want something that will hold the phone firmly and allow me to talk while driving as I can get "Bixby" or "OK Google" to answer any calls for me by just using that feature.

2)  A good protective case for it that doesn't restrict any functions like the buttons and camera and hopefully, still being able to use my Finger to unlock the phone while it's still in its case.

3)  A suitable charging cable that will plug into my car's cigarette lighter socket.

Cost of the items is not so much of an issue, the quality of the products, however, is.

Can anyone suggest a good place to purchase the above items online?  

Also  perhaps suggest what you use for the above purposes if you own the same phone?

how to take print screen or screenshot on moto 4g plus

Hi All

Does anyone know who in the UK sells pre loaded 4g data sims that do not require a contract and not restricted to being used within 30 days?
I live in the UK and have a friend visiting from the USA soon.  She is tied to AT&T on her smartphone.  What are her best and cheapest options for bringing her phone here to the UK and being able to use data, make calls, and send texts back to America?

Ideally looking for American experts who have travelled to the UK recently and have set up some kind of calling plan through AT&T that worked out well.  Unfortunately international use of mobile phones is not my strong point.
I am looking to receive SMS text messages on Ubuntu. Have tried At&t/Cricket wireless SIM cards with Huaewei (USB modem) and Nokia phones connected via USB and no luck. Looking for a complete solution. Will pay reasonable amount for the right solution. Preference is Ubuntu but will consider other linux flavors.
How to determine if cell phone is locked or unlocked ?

In the settings, there is Model Nokia Lumia 928, Carrier is Verizon Wireless, and IMEI number.  There is no sim card in the phone.

How can I tell for certain that this phone is locked or unlocked?
I need an Android App that will suppress any ringing on my phone, allow the playing of a Voice message advising the caller to unblock their number (Ie: Enable Caller ID) and call again.

Ideally, there would be no ring on my phone by calls without caller ID enabled and they would automatically get rejected and given the opportunity to leave a voice mail with a return number.

This would take care of 95% of the spam/scam calls & SMS's that I receive.

I do engage in the occasional scam baiting, so I'd like to have the option of letting those calls through occasionally when I'm in the mood, but for the most part, I want all private numbers blocked.

Anyone know of such an App?

Harassing, bothersome, invasive, disgusting, time wasting, infuriating and in general garbage cell phone calls! This question is ONLY for an Expert that can tell me if my idea is possible. I would prefer it if I NEVER get ANY cell call if it is impossible for me to return the call. If whoever or whatever is calling me does not care to be identified then do NOT ring my phone. I believe that it is possible technology wise to have the cell provider determine, instantaneously if the number trying to reach me is one that I can or cannot dial back. If I cannot dial it back then do NOT put the call through. Simple. I would pay DOUBLE my cell bill gladly if this were possible. Why isn't this idea being implemented? If POTUS were to get some anonymous or threatening or just plain bothersome phone call I can guarantee that the caller WOULD be identified and the calls would stop. Why can't the average citizen be granted or allowed to opt in to such privacy? There ARE cell company technicians that KNOW if this is possible or impossible. I am looking for someone like this to explain the situation to me. The providers are in the business to MAKE MONEY. Naturally. I am willing to spend MORE money but they seem clueless to want to cure the problem. The "Do not call list" is a total and complete JOKE. I now frequently leave my cell on my desk simply to avoid the hassle of these annoying calls. FIND THE DAMN PEOPLE CAUSING THIS AND PUT THEM BEHIND BARS is my solution number two. Any sincere …
how can I tell if iphone 8 on ebay is fake.

Do I just look at feedback rating of seller.
If seller has more than 1000 feedback then phone is probably real.
ebay lists iphone8 64g for verizon $516-$700

verizon wireless united states store sells for $900 (total after hidden fees/taxes)

Yes it is better to pay monthly for 2 years.

Only other benefit is 1 year warranty. If something happens to phone from verizon store; it gets replaced


Could I buy ebay phone and buy a warranty for cheaper than $386

Hi everyone. I have an Android 7 device. It's not rooted. I need a file manager/utility that allows me to view the files & folders of the root directory; specifically the System and Data partitions. I don't need 'Write' permissions, just Read-Only. I want to copy some files. In other words, I don't want to root the device. I just need read-only access. I would prefer a file manager type app but I'm open to other methods.

I have tried Solid Explorer. It shows the System Partition but not the Data partition. Thanks.
I am certain that the majority of cellphone users are annoyed by the number of solicitation calls that they receive. I know that I am annoyed for sure. The great majority of the calls in question display numbers that cannot be reached. Is it not possible for, at the customer's request, have the carrier determine if the number calling my phone is one that can be reached by me? And if it is not reachable by me then do NOT put the call through at all.  End of problem. These days when data related things are happening at lightning speed it would be a feature that would take less than 1 second to do the check. Seems like a wonderful idea to me. I'd actually be more than happy to pay an additional monthly fee for this service. Are there any cellphone technicians that can tell me why this would not be possible?

I want to fix phone without resetting phone
My Samsung S7 (T-Mobile) won't boot up. I've been trying all the recommendations here https://thedroidguy.com/2018/05/fix-samsung-galaxy-s7-wont-boot-android-7-nougat-update-troubleshooting-guide-1069678 but can't get anything to work. It was working perfectly fine and at 60% battery, I put it back in my pocket and took it back out and it was just a black screen.

I have tried two different chargers and let it charge for at least one hour. When I try to recovery boot by holding down the Home key and Volume Up at the same time I see the blue "Recovery booting" text but then it still won't boot.

I'm on chat with T-Mobile trying to figure it out but nothing insightful yet. Has anyone else run into this or know how to get this darn thing to turn on?
