Fix for Data Problems on D80020y - AT&T LG G2

This is a bit of a late post, but data problems with the new APN, AT&T NextGenPhone, can be caused by your AT&T account having provisioning for an older device, or an iPhone. I found out that my account was provisioned for an iPhone 4 and I was unable connect to the data network when I updated to D80020y and sometimes I had LTE problems on previous firmwares. After calling to have my provisioning changed, all problems regarding my data went away. Also, changing the APN back can sometimes work of course.

Data on AT&T with Verizon (2.05.00WU)?

I security unlocked and flashed the patched radio, but now I can't use data. I tried changing the connection settings (I added a MEdiaNet connection in My ISP). I only need it to use MMS, but this is getting frustrating; what am I missing?
Im in the same boat with you BT, unlocked vzw tp2 to use on at&t. sms and voice work without any hassles. but medianet is being the biggest pain. i fussed with the settings for two days and finally got everything working flawlessly. then i restarted and apparently verizon programmed it so that it always writes vzw's wireless settings back. im guessing i have to try a rom in order to stop that. ill let you know if i have any luck.

T-Mobile APN

My MyTouch is actually a HTC Panache from Moblicity, which is apparently the same phone with a different name. I usually use it with WIND Mobile, and when I go to the US, I use my T-Mobile SIM. On my old Hawauai U8100, this was not a problem, and all APNs changed automaticly, and i had no problem using data in the US or Canada. On this phone, however, APN setting are cleared every time i remove the SIM. I already have the settings for WIND and T-Mobile, so I can re-enter them every time, however i noticed that T-Mobile uses the AT&T network in places that there is no T-Mobile coverage (such as upstate NY), so when I am there I only have voice & SMS, but no data, as I do not have AT&T APN setting.
So first of all, I would like to know how my old phone got APNs automaticly, and if that would be possible on the MyTouch, and if not, what are the APN settings for the AT&T network that is shared with T-Mobile?

[Q] How to Restore Lost Data Connection

I'm new to this forum, so if I've posted this in the wrong place, please move it.
I have an AT&T branded Galaxy SII i727 Skyrocket (4G LTE). It is not unlocked, has not been rooted and runs AT&T firmware. The phone was purchased independent of a contract (eBay). I am a very light user, but I find it convenient to have a data plan and initially used AT&T GoPhone prepaid. Phone and SMS worked properly, but some tweaking was needed to get data to work properly. After a few months, I switched to Consumer Cellular (AT&T MVNO). Initially data did not work, but CC's tech support gave me revised Access Point Name settings and all became as it should be.
Last week (or maybe the week before), I finally gave in to the phone's insistence on updating to a later firmware version. From then on, I have been unable to get data to work at all. the 4G symbol no longer appears (although I doubt it was ever actually a 4G connection) and any App that requires a data connection (web, email, etc) complains about no connection. WiFi, on the other hand, works properly with all such Apps.
Here are the specifics on my phone:
Samsung SGH-I727
Android 4.04
Baseband Version I727UCLI3
Kernel Version:
3.0.8-1127534
[email protected]#1
SMPPREEMPT Thu Sep 27 23:12:45 KST 2012
2012​Build number IMM76D.UCLI3
My questions are these:
1. Has anyone had this sort of problem (data on CC fails after upgrade)? If so, how did you solve it?
2. Was this problem caused by the upgrade? If not, what other issues might have caused it and how can they be corrected?
3. How can I revert the firmware to the previous version to confirm the cause and/or resolve it?
4. What else can I do to get my data connection back?
I am not particularly Android savvy, but I am not shy about making changes in settings and/or installing fixes.
Thanks,
Tenaya
I am having the same problem. Same phone set up. I switched from AT&T and installed a Net10 sim on there bring your on phone. Installed been working great. Then it just stopped no data connection. 3g 4g no signal nothing. I have been searching for solution while reading the noobie guides. still looking for someone, a thread, or just a link to where i might start to solve this problem.
Check your apn settings and make sure they are correct for the SIM card. Check with the carrier for the correct settings.
APN settings, I almost guarantee it. Check to make sure they are correct for your carrier

yes for anyone else having this issue I had the same issue after flashing a new ROM and this was where the problem was.

SCH-I535 no LTE but 3G and Cell service works

Hi all, I have a bit of an issue that I can't seem to resolve. Currently running CM10.1 RC5.
LTE does not work, 3G is fine. After some research I decided to do a factory wipe and reload Cm10.1 RC5, no positive results. Then upgraded the baseband to I535VRBMB1 from I535VRLG1 with no positive results.
I verified Network Mode is set to LTE/CDMA/EvDo, System select is Home Only and CDMA subscription is RUIM/SIM.
I found out that if I change the CDMA subscription to NV, LTE will activate and work properly but cell service does not work. I verified this with wireless disabled and used a Speedtest application with results of 61 ms, 5441 down and 6260 up.
This issue occurred as of RC1. One other item to note is I attempted an update by dialing *228 and pressing 2.
My network provider is Verizon Wireless.
Any assistance is greatly appreciated.

Fixed. I followed this procedure http://forum.xda-developers.com/showthread.php?t=1974114 to bring my phone back to stock, rooted w/recovery and VRBMB1. Wiped data, cache and davlik in recovery. Booted up and did not sync any content. Called Verizon Wireless and had them reprovision my SIM card. The tech told me turn off the phone and he pushed out updated roaming and updated tower information to my phone. Booted up and after ~6 minutes 4G activated.
I have since installed CM 10.1 RC5, synced with my apps and data, and I have maintained 4G service since.
If you have a 4G phone with Verizon Wireless, do not attempt to update roaming/cell tower info by calling *228. Instead call Verizon and have them push the updated info to your phone.

Software: Android 5.0.1 Skydragon M8 v2.0 Sense 7
Many people have posted issues with LTE where their cellular signal was fine for "2G" functions like calls and texts.
I'm having the opposite problem. After leaving airplane mode (landing at an airport today), I have a "No Service" message in the status bar drop down (notification tray), and the Settings>Network information page shows "Not Registered." However, I do have an IMEI (see details below). However, LTE data works perfectly fine.
I've obviously tried changing the settings in Settings>Mobile Data (preferred network to Global / LTE / LTE/legacy 3GPP mode) connection type global/auto/LTE/etc), to no avail. If LTE is connected it works flawlessly, but I cannot make calls or texts, and show not registered on the network. Data roaming is set to deny, but even allowing roaming does not change the situation.
Before this happened, I HAD gone through all the XTended Settings, and even 'looked' at (but did NOT change) some advanced settings pages, including the 'hidden' HTC network info page ( *#*#4636#*#* ). Again, however, I didn't change anything -- unless by accident?!
Does this sound familiar to anyone? Anyone know if I may have inadvertently changed something and can change it back (a setting that would persist in the hardware through NANDROID restores and factory resets...). Or, any other advice to restore the cellular service connection to normal?
I've tried a full NANDROID restore (multiple times) to a working copy, and a factory reset. I have limited access to a PC since I'm traveling, so re-flashing the VZW firmware or stock recovery or lollipop/verizon RUU would be challenging.
I did spend a good 45 minutes (at a library, my only PC access!) searching the forums and web, but to no avail.
Settings information:
OPperator Name: Verizon
Signal Strength -114 (I've had better but still have the same issues)
Mobile Network type: LTE
Service state: In service
IMS service state: Not Registered
Roaming: Not Roaming
Phone Identity page:
IMEI shows up (15-digit number...how can I verify I didn't mess this up?)
Phone Number is correct
IP Address: 100.66..... (looks good)
Any help is GREATLY appreciated!
Same here
I'm having the same issue. When i try to make a call my LTE bars drop to nothing and it says call failed no network available. Any ideas or help would be nice. I was using venom rom as well. I'm currently trying to flash the newest RRU to see if that resets things. I'm wondering if it somehow my sim card. I took it from my droid turbo. I've made sure to turn off advanced calling on my VZW account though.

I had this same issue, running from ruu then rooted. I didn't noticed until I started seeing voice mail notifications but never heard the phone ring. When I tried to dial out I got the immediate call lost message. I couldn't figure what was causing it so I just did a reset. I made sure not to restore any systems data from prior to the Lollipop upgrade. At this point everything is working, the only thing I haven't installed yet is the xposed framework and sense 6 toolbox.

What kind of reset did you do? I know my issue is slightly different, but I did a full RUU-flash yesterday (latest lollipop version) and still no luck. Unfortunately I'm out of the country now and access to a computer is limited, and I don't even have a SIM card yet to check if cellular service would work anyway.
I do intend to do a flash of the stock recovery and radios once I have the time and access, but that may be a while...
Still, I'll keep checking this thread to see if anyone posts any other options

Just go into settings and to Backup & Reset , this will return your phone to a fresh install and remove all non bundled apps.
Before doing the reset try going into Settings then Call then change Preferred Network to Global, or toggle from LTE then back to Global.
