APNs switching?

Starting about .. oh, 3 or 4 months ago, I've noticed my phone dropping data, OR, getting stuck on 'E' or 'G' symbols, even in areas that have LTE. Every time I notice this, I go into APN Settings, and I find that the selected APN has changed. (Usually from 'T-Mobile US LTE' to just 'T-Mobile US'..)
I don't have any APN apps or anything, but have been running AOSP v4.3 (then v4.4) since about the same time this started.
Any ideas on what to check? Am I going crazy? (Is my phone going crazy?)

You could delete the APN's that you don't want it to switch to. Just leave yourself with the one you want, and it shouldn't be able to change.
Now that MIGHT cause it to switch to nothing, leaving the phone without any connection. But if that happens a revert to the nandroid backup you make before trying this would fix it, at least back to what you have now.

I went ahead and tried this. So far, everything seems to be okay. I'll keep an eye on it for the weekend, and see if any oddness occurs.
Thanks!

Okay -
This didn't work, but it DID change the.. er.. way to fix -
What happens is that the data symbol will vanish - no data. Voice works okay. Since there's only ONE APN, if I go into the settings, it's still selected. (Leading me to believe that when I had multiple APNs, the top one WASN'T actually 'selected', the code was just marking the first one as active, when none were. Silly Radio lists..)
I had to add and save a 'dummy' APN entry, then select it, and then reselect my real APN, and it starts working.
It happens maybe once every other day, so it's not a big issue.

Have you tried to force LTE?

Yeah - the phone seems to ignore that. Meaning that, it will still drop data, forcing me to unselect and reselect.
Though, I spoke to the developer, and it looks like it's a ROM issue, actually, and I'm running the lastest build now, which is *supposed* to have the fix. We'll see after the holiday tomorrow.

Can't Make Calls/No Data

Hey everyone, I can't seem to recieve/send text messages and I cannot place calls (says EMERGENCY ONLY)
I am on the T-Mobile network and have done nothing to my phone that could've cause this. I still have signal though.
I tried:
-Flashing 10c and 10m modem
-Reboot
-Turn on Airplane mode and turn it back off
-Took out sim card, put it back in (while phone is off)
and nothing worked. I also tried put my sim card in my Galaxy S3 to see if I get data and can place calls, and everything on the Galaxy S3 works fine! But not on my G3
Here is a picture that shows my network status. I also still have my IMEI, it isn't lost. So what could've cause this? And what can I do? :crying:
I'm in Austin, TX if that matters.
Thank you!
Edit: Fixed my problem! Callled T-mobile and they removed an accidental block on my phone (weird...).

This crap happened to me yesterday too!! I think I ended up disabling mobile data, changing the Network Mode to another setting like WCDMA ONLY for a minute… once I put Network Mode back to the GSM/WCDMA//LTE only and turned mobile data back on it was fine. It made NO SENSE though!! How can you have service and full signal, but only be able to call 911!?!? Another BS T-Mobile glitch! I'm SERIOUSLY going back to Verizon this weekend I think. No wonder T-Mobile is cheaper and Verizon is more expensive. Why do I ALWAYS forget that YOU GET WHAT YOU PAY FOR!!!

I also disabled most of my xposed modules too. Not sure if that did the trick or not. I did several things. I'll let u know if I can remember any other details to how I fixed it. Good luck bud.

Update: Restoring an early nandroid backup DID NOT fix my issue

I fixed my problem! I called T-mobile and they said someone filed an insurance claim on my account! Apparently it was a glitch in their system. I'm actually shocked that something like that could have happened. That's really sad. Oh well, my problem got fixed! Thanks for your help!

Exclamation mark on wifi and cell signal

So after rooting and installing latest Cataclysm (Jan 6th update) with ElementalX I get this exclamation mark on my cell signal and wifi.
When that happens, I can use Facebook, Whatsapp, Youtube and I am able to make calls, texts, etc. What I can't do is load any page that isn't a google page on my browser. Also, I can't load anything on my Reddit app that isn't a text thread. Images, videos and anything external in general, won't load.
When I restart my phone, everything works fine. As soon as I lose signal or turn airplane mode on/off, it appears and I can't get rid of it.
I tried:
Resetting my APN settings.
Reinserting my SIM.
Changing preffered network to 2G/3G/LTE.
Resetting network settings.
Flashing ROM again.
Flashing original EFS again.
Wiping cache/dalvik.
I have no idea what to do or what is causing this issue.
Please help.

Go back to stock ROM and see if it happens there, if it does it's a carrier issue if it doesn't it's likely a bug with the ROM/Kernel you are using.

What carrier are you on? Have you check and/or re-verify those APN settings ? Next time this happen, turn on Airplane mode for 15 or 30 seconds, then turn it off again - do you have a decent cellular signal ?
I'm running PureNexus with EX rom and it's fine, solid (and stronger) signal on T-Mobile vs. N5 used by spouse.

Im not from the US or something popular but trust me I verified my APN settings.

ideaman924 said:
I saw it sometimes on my custom ROMs, nothing to worry about though.
If you enabled data and you don't get the LTE sign, then try going into the Hidden menu and setting LTE to automatic. I forgot the hidden code though, can somebody else supply it? Alternatively, you can go inside settings>others>network>apn and check the apn, then go out and change the option to LTE (recommended) or something

Is this occurring with the MMB29P radio and vendor installed?

Do you use Adblock Plus? I had the same problem. Switching Adblock off and on solved the Problem. Apparrantly they have a problem with Https connections or something

Losing data after wifi disconnect

Been having this problem for awhile now, but it's getting more frequent.
If I'm connected to a wifi network, be it home or work, and I then step away from it, my data connection will be stuck at 1X (ie no data), even if my signal is at max bars, and I'm in an area where I know I've had data before.
Sometimes toggling data or airplane mode will bring it back, but that fix is working less often now. Rebooting the phone seems to fix it, and I'll immediately get 4G LTE data. But this is happening every other day now, and I can't keep resetting the damn thing every time I get into the car in order to make sure that my email and messaging apps still work.
Is there some way within the settings to force the phone to reestablish data with the tower without resetting?
EDIT: Took it to Verizon, who gave me a new sim card. Will test for the next few days and see if that fixes it.

Update : the problem resurfaced. As usual, reseting fixed it, but this is getting obnoxious. I'll take it back to Verizon and see what they say.

i have this issue too, any updates?

Well, I received a new phone overnight via FedEx, and the new one hasn't lost its data connection yet.
So yes, I supposed it's "fixed"... But I wouldn't really consider having a new phone sent to me a "fix", since this option is probably not available to all users.

T Mobile wifi calling not working on Pixel 2 XL? Is it a setting?

Hi, I just switched from Project Fi to T Mobile and wifi calling is not working on my Pixel 2 XL. If I'm in airplane mode, turn on wifi, and make a call, it gives me an error that says "turn off airplane mode or connect to a wireless network to make a call."
My searches on the net seem to show varying results with it seeming to work for some and not others. Please help! Please respond if you have a Pixel 2 XL on T Mobile and if wifi calling is working for you in airplane mode. I assume that a true wifi call on the Pixel will show a wifi symbol on the call screen, as it did for me when I was on Project Fi.
Thanks!

Just tried. Haven't used the wifi calling as I have a T-Mobile LTE hot spot and haven't needed to at home since. Worked fine though on stock 8.1 no root. Airplane mode active, WiFi on.

Never turned it on until I tested it out, I'm on 8.1 stock unrooted March patch and it works just fine.

You guys are giving me hope. Thanks so much for responding. I need to find out what is different about my setup than your two.
Did you get your Pixel 2 XL from Verizon? Mine's straight from Google/Project Fi. I don't THINK there's a difference, is there?

I don't feel like there's anything significant in here. Any ideas, guys?
When you were on a Wi-Fi call that you placed, did you have the little Wi-Fi symbol on the call Page above the name and number? That's what I remember when I would make a Wi-Fi call using project fi on my pixel 2 XL.

You do know that you enable WiFi calling through your mobile network settings right?

Mine works fine also, I'm using WiFi preferred in settings also if that makes a difference,

The key for me back when i had tmobile was to register a 911 address on My T-Mobile. (Note: If you skip this step, a REG09 error may be displayed.)

Great suggestion, thank you. As I just started my T Mobile service yesterday, I had not entered an e911 address yet, which the store rep had asked me to do. However, I just added it and still have no wifi calling ability. That said, I'm not sure if this takes time to work, in other words now that I've put in the address if it takes 24 hours or something?
The other thing is that based on the error message I get, which I posted on page one of this thread, "turn off airplane mode....", it does not suggest a problem with the e911 address. It feels like a settings issue to me. An advanced settings issue. All I've got is a gut feeling and nothing to back it up. I've asked T Mobile for help on this and they are only somewhat interested because my phone is not a T Mobile device.
And that link you've included is GREAT because it officially suggests the Pixel 2 has wifi calling capability on T Mobile. Not the Pixel 2 XL but...it still might be good ammo for me when asking for help when they're not so interested.

Thank you for posting this picture! This is exactly what I'm looking for and what I recognize from successful Wi-Fi calling on Project Fi recently. I can tell that you feel my pain here and I appreciate it.
Another indication I'm noticing is that when I'm in airplane mode and Wi-Fi is on, I get a "no connection" indication bar in Android messages. See the attached thumbnail. That should not be happening and further indicates something is amiss. I think when that goes away I will have with Wi-Fi calling capability.

I had to enable the wifi calling within the phone app and it worked.

I've definitely done that, and gone through all of the menus.
To add insult to injury, my wife's MotoX4, on the same account and also brand new to T Mobile, has perfectly functioning wifi calling.
Thanks again for all of the responses. I may try going back to the store and having them re-provision my phone, in case something didn't get done right initially.

Whatever you don't, don't let any T-Mobile idiot try to lie to you saying you need a T-Mobile branded phone for wifi calling. When I was having issues getting this setup, one of the Tier 2 IT techs tried selling that line of bull****.

I know, I've received that one already. But there's way too much evidence on here and other forms to suggest that it absolutely works with the pixel 2 and can be done. I just need to find someone at T-Mobile who's willing to work on it with me.
If anyone has a contact at T-Mobile who they like, PLEASE let me know.

Would anyone who hasn't already specified please let me know if your phone is a Verizon specific device as opposed to the Google Store Pixel 2 XL? No one has said that their Google version has wifi calling working yet and that is the only thing I can think of.
Thank you!
