Mobile data cutting off and cannot connect to LTE - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

So the past couple days my mobile connection is being cut off, for around 30-45 seconds every 10ish minutes. It comes back on its own but it's getting kind of annoying.
Also, my mom and brother have gotten lte on their phones which made its appearance yesterday for the first time in my neighborhood, and I have yet to get it, we live in the same house. You think maybe these have something to do with each other? On jelly bean running BlackJelly rom

Sounds unrelated, but does your GPS currently work? I had the same issue with data and LTE the other day and my GPS didn't work. But I've since been able to fix my GPS and that also fixed my data dropage (can't test LTE).

I opened up maps and gps is working fine, so is Google now. Is it possible that it's just a simple sim card issue?

It could be. It's more likely an issue with your APN. There's a specific one you have to use for LTE to work (under the assumption you're on ATT).

Really weird Data/Voice problem

My phone came up with two triangles with exclamation points on it in the notification bar. One said data access restricted and the other one said voice access restricted. My phone was fine and when I got out of the shower those notifications were there. So, after that my voice and data would not work. I rebooted and voice came back, but data is gone. I cant connect to 4g/3g or anything. My IMEI is there still. I didnt flash anything. Anyone have a clue what might be causing this?

Is your phone roaming maybe?

I'm not sure. I know under data it just said disconnected. It didn't say roaming. Btw I'm talking about using the phone info app to see status. My voice showed bars, but when I tried to make a call it said not registered on network. I rebooted and moved my phone to a good reception spot and data is working. So strange. Does this phone say when it roams?

It should.
Also, go to settings, more settings, mobile networks and check data roaming. If it happens again it should definitely tell you.
Make sure your plan covers nationwide roaming so you dont accidentally get charged.

Anyone else having issues with GPS in NYC?

I haven't been able to get a gps lock since yesterday after using navigation on my phone. Any time I open an app that uses location services gps will kick in and will stay stuck on searching for location
Not sure if this is a widespread issue or something wrong with my phone

I guess the weather doesn't help things

I'll assume with all that went down there could be extra cell usage and cell towers not functioning. Cellphone GPS does use the cell towers for location.

[Q] Play store slow on LTE since ZVB

Ever since I've updated to zvb stock zip the play store downloads apps on LTE very slow. It will go about 32kb a minute, but I do a speed test in a browser and it is getting over 10megabit. Any ideas? Everything works flawlessly besides that
I'm experiencing the same thing. In a location with excellent lte coverage I was unable to download a 32mb app today because of error after error.

That's what I was thinking, but I pulled in my drive way, phone connected to wifi, and restarted the download and it instantly came through

I tested it from two different LTE towers yesterday and neither would budge. But today on my way to work i tried downloading an app and it came through instantly, just like WIFI, so the issue seems to have resolved itself

Cm10.1 data switching issue

When I turn on my data it switches between 3g and 4g and I can't even figure it out
Sent from my SGH-T999 using xda app-developers app
That is how it is supposed to work, nothing to figure out.
My gfs phones never switches or anything my phones does all the time
Sent from my SGH-T999 using xda app-developers app
What is she on and it never switches to what? If she hasn't updated her modem it will stay on 3g all the time. It is like this on every AOSP rom for our phone. Unless there is a theme that edits it out.
If speedtest says it's fine, it's fine.
It just switches from 4g to 3g all the time but I guess I'll have to live with it

Mobile connection/mhl-hdmi adapter issue

I have the Samsung OEM mhl-hdmi adapter, and when I connect it to my TV my mobile network turns off. Like an "x" showing near my bars. Running slesh's 4.3 sts 1.2 odex rom. But I noticed it on jellybomb

Is anyone else experiencing this issue? My wifi connection will stay on just fine but not the mobile connection. So no 3g/4G, can't receive calls or texts.

I have the same issue using classic rom but I have 3 phones cloned to same number so irt is not really an issue for me.

Yeah I have my number linked up to my note 8.0. But when I don't have my tablet on me, it can be a pain. Not as bad as my old evo 4g, there was no way to keep text or calls in the background when connected to hdmi, interrupted all movies lol

Moved to Q&A.
I believe its the adapter not so much the phone. I have a third party adapter and when I first got it I would lose reception. Now I actually get reception and dont even use wifi to stream movies or shows..
