Okay. I went through this a whole lot with this phone, and on almost every custom ROM it has. Lineage ROM is the only one that has worked for me right after install. I'm not sure why it does this as the APN settings that comes with the Roms are exactly correct. However you will not be able to get your full service until you manually add the APN settings in yourself. You can delete the 2 other APN's if you want. It really makes no difference. But you will literally have to make a new APN with the exact same settings as the 2 original ones in order for your DATA and MMS settings to work. Once you hit the "save APN" button you should see the 4g or LTE symbol pop on and everything will work just fine. Good luck. Let me know if you still have trouble.

MMS&Data Connection Problem..

Apologies if this has been posted before, I have tried to find topics similar, but have found no resolution thus far.
My X10's data was working perfectly, then about 2 weeks ago, market stopped working at "Starting Download" never completed, and I couldn't download Apps! This suddenly fixed itself one night randomly, and all my apps downloaded and installed, but instantly the market problem continued when I tried to use it again!
Now, the 3G/2G connection is totally non existent, there is NO icon at the top.. I have tried restarting the phone, turning it off and on, sim and battery out, even calling O2 to get correct APN settings (Server field is black, is this right?) and I got no "green light" beside "mms" at the APN type field..
The signal was fantastic before, and my family are still getting 3G connection on their phones, so I ahve no idea what the problem is.. I installed a few battery saving things which Iv since uninstalled.. but i have no clue what to do!
Any help would be much appreciated.. Thankyou!
suggest backing up your apps and then doing a factory data reset.. it's a pain in the proverbials but worked for me when this happened a couple of months ago.
How do I go about doing this mate? Any easy way?
Hi - Before you do this.. Can I just check something.. have you check in your network settings that it's not switched off... settings; wireless controls; mobile networks; MMS and data (needs to be on!).. and network mode - best to have it on GSM/ WCDMA Preferred to make sure... otherwise.... to answer your question above..
That will depend on whether you've already downloaded a file/ app manager such as ASTRO which will allow you to back up the apps.... if not you'll just have to make a note of which ones you want to reinstall and re load them after you've reset the phone.. the reset is done in the settings menu - sd card and phone storage - factory data reset... it will reset your phone back to how is was when you first got it though..

NO DATA?!?!

I changed ROM's and I cant get data back. Ive tried multiple and its a no go. I NEED my data. What do I do? Ive checked my APN settings....help!!!
what network are you on?
have you tried deleting all other APN's except the one you need?
Do you have signal at all / are you connected to the phone network and able to take / receive calls? or is nothing working?

I am on Straight Talk.
I just deleted the other "ATT" apn that was there. Currently only have the ST one selected and present.
I have "H+" in the notification pane and its "blue" meaning what i thought was "active data". But nothing

has the data worked at any point before?
This is the problem that lots of people over in this thread are having ...
http://forum.xda-developers.com/showthread.php?t=2084706&
We are hoping for some sort of fix to this in 4.2.2, but until then we haven't been able to find a solution. If you are 100% certain the APN settings are correct (I can't help with that as from UK so not familiar with that network) then there isn't much you can do. For me, the only thing I ever find that sometimes brings it back is if I turn airplane mode on, leave it for 30 seconds then turn it off again. Likewise, you can click on the APN to reset that each time.
If you are rooted, Faux released a modified kernal which is meant to improve data drops and the wake issue which some nexus's have.

did you cut your own micro sim?
try a spare sim if you have one.
Reset APN to default, delete all and try again.
I don't know what else to suggest other than the above / phoning google / rooting and trying a different kernal and ROM / wait for 4.2.2 update.
(In the meantime please post in the thread linked above, no need for this duplicate thread just for your issue )

Which ROM were you on when you first noticed the problem?

No Internet connection after software update to MHC19I

Hey fellas,
I just recently updated to the latest software version via OTA (running stock), and suddenly I cannot connect to the mobile Internet anymore even though it shows everything correct.. APN, cellular company and signal at the top of the screen..
Any idea?
Thanks
I've been having the same problem having updated to Pure Nexus last night and again this morning with very little help. When I went into the APN section the actual APN was not selected and that at least got me data but I cannot make phone calls out. They keep getting some sort of sim error.

Not sure if it will help, but have you tried flashing back to an older radio?

That's impossible to check since I'm in a vacation :S
I had this same problem. Go to your dialer and enter
*#*#4636#*#*. This will get you in the test menu. Select phone info and click the 3 dot menu on the top right. Choose select radio band and then click USA band if that's your location. Reboot your phone. Now turn airplane mode on and go to settings and click more under wireless and networks. Click cellular networks and system select. Toggle home and automatic back and forth. Now toggle allow data when roaming off and then back on. Turn airplane mode off and you should be back up and running again. These steps worked for me anyway.
Solved my issue. Go to pure nexus setting, all the way at the bottom I have a phone and info. Then go into phone information. Then click menu in top right, select the band that works for you (had to set mine to USA, 6&7 Didnt work

x below lte signal and not internet connection help!

Hello so as stated above for some reason i have an x below my signal bar but it still says lte but not connection, ive tried the following, remove sim and put it back in (both with the phone off and on), checked my apns which i never had to mess with before (which i didnt have this issue yesterday just saw it when i got to work which i usually have lte signal), turn on and off airplane mode, turn off and on mobile data, ive tried every fix i could think of so far with none of them working.. my cell service is been paid and i checked my straight talk account to make sure, but now comes the weird part when im connected to wifi and pull down the quick toggles it shows no x under the lte (see screenshot below) does anyone know how to fix this issue i rely on my lte data for directions and gps at work.
Phone info:

Thanks to anyone that can help!
I am having this same issue as of this morning, and I am on the Straighttalk AT&T network. I wonder if they just updated their APN network and our APN settings need to be updated too? If so, I'm not sure what settings to use.. using the straight talk website and selecting "Android 4.0" (the newest version listed), it shows the settings I'm currently using. Anyone else having/resolved this issue?

Borrow a (different carrier) SIM from a friend to see if it is a network issue. If the LTE works on that SIM, go to ST and have them provision another SIM for you (free). If the LTE still doesn't work, back your phone up, wipe it, flash a full image.

I called STW tech support, and they told me I had the wrong APN... I updated my APN settings (but really it was nothing other than changing the ID, so I don't think it had any real effect) and still had no data. After checking downdetector.com, it appears there is a widescale data outage with straight talk (or more specifically, AT&T). One of the commenters stated the following:
"I can confirm the issue is DNS. If you have the ability to changes the DNS on your phone, you can restore service. If you have Android + Root, I used DNS Override successfully. Just set DNS Servers to Google's"
I just used DNS Override ($2 app) to set my DNS servers to Google's and that resolved my issue. Hope that helps. If you don't want to spend $2, there are some free apps that also will change the DNS servers for you, and there are other methods detailed here: https://forum.xda-developers.com/ge...ide-how-to-change-dns-android-device-t3273769
Update: earlier that day ot seemed to resolve itself while i was driving at work amd got to my destination which was about an hour away and once i looked at my phone ot no longer had the x and had full service amd working lte so idk maybe it was cell tower maintenence but don't know for sure but the issue hasn't happened again tho but thanks for everyone for the help and suggestion!

Verizon APN Not Showing Up

Hey all, I'm running 9.0.16 completely stock and out of the blue today my phone just lost signal.
I've always had full bars on 4g in the area I'm in and even when I go outside it still wont connect. When I go into APN settings for the sim it "apn settings not available for the current user profile" and won't let me add anything because everythings blurred out and theres nothing to edit because there are no options listed to begin with.
I tried all the basics like erasing cache, removing my sim, refreshing network stats and changing my signal type through 4636 but nothing's working and at this point I don't know what to do. I don't have another phone on me to test if its the sim or the phone and I'm not in a financial position where I can just get a new one atm. I'm away from home until december and I don't have any other spares w/ me either. Help would be greatly appreciated. Thankss
This may not be the answer you were looking for, but maybe get all your data of the phone and try a factory reset if nothing else works.
ive had issues on stock and custom roms with this. you may have to wipe user dat, try a diffrent rom, if you do custom software, ive called verizon now a few diffrent times and try telling them about cdma-less feature, or feature code #83856
