[Q] Galaxy Nexus won't connect to 3G (Verizon), any suggestions?

All of the sudden yesterday my phone stopped connecting to 3G. I can still connect to 4G when available. I can make/receive phone calls and I can send/receive texts. I am fine when on WIFI. I have no data connection on 3G.
I have tired everything I can think of. Toggled LTE / CDMA. Factory reset the phone. Called Verizon. Nothing helps. Under Settings / About Phone / Status / Mobile network state it says either connecting or disconnected when on 3G.
I reactivated my incredible and the 3G connects right away. I deactivated the Incredible and went back to the Nexus and I still have no data.
Does anyone have any suggestions to try on the Nexus?

dial *#*#INFO#*#*
Go to phone info and turn off 4G for a moment and when conencted to CDMA then press menu (its the colon) and then ENABLE DATA CONNECTION.

If that doesn't work, I would go exchange it, you may have a bad radio

I have a replacement coming but I'd like to see if there was something else I can do to get it to work for the weekend. I have had the phone since the release date and it's just yesterday that this started happening

Why not flash a new radio if the cause is a bad radio..

If I have WIFI and 4G off it doesn't even give me that option in the menu.

[Q] Network Issue with rooted T-Mobile Galaxy S3

So I've had this phone for over two week now, and I rooted it and flashed it with FrostyJB v5. Everything was running well (excluding the battery life, which was better in v4 but that's a different topic). I was at my school connected to their wifi earlier tonight and when I left school, I can't make any phone calls (i have a circle with a slash through it where my signal bar would normally be). I think it has something to do with my APN or network or something? I'm honestly new to this. I would appreciate it if some one could help me solve this problem. The phone is a T-Mobile phone, which I bought from a T-Mobile dealership. The SIM was working properly until tonight. I tried removing the SIM and rebooting, putting the SIM back in, rebooting. etc.
TLDR: My 4G doesn't work, I'm not connected to any APN, my phone is rooted and flashed with FrostyJB v5 but I bought it from a T-mobile dealership with a T-mobile sim card. Help. Please.
I can provide addtional information if needed

my imei is still there. it is not in airplane mode. I can't connect to my 4G or my T-Mobile network. I was not doing any development when it suddenly turned off. I was walking out of my school around 11:00pm CST (if it helps, I get no reception at my school's building). I turned my wifi off and turned my 4G on via drop down menu and it wouldnt connect. I tried rebooting my phone several times, using HOT BOOT and REBOOT.

Can an mod/admin close this thread out? I solved the issue. You need to turn off wifi calling for it to work. dur. sorry

[Q] No data connection 4G/2G/E

Hey guys, I picked up a new Samsung Galaxy S II (T-Mobile) about a month ago from the retail store.
About a week ago I was using my phone as a hotspot for my xbox and then I got disconnected while playing. I wondered what was the problem and I saw the data icon was in the no connection state. Now I restarted the phone in case it was the simple loss of signal bug but it wasn't. My data wasn't coming back on. No matter what I did the connection wouldnt come back on. I called the tmobile tech support and they gave me rubbish things such as reboot phone, take out battery and wait 20 seconds, and all that jazz. I then noticed a pattern starting with my phone, the phone would connect to 4g then a second later disconnect. It would repeat this all day and not change to anything else. If anyone can help with this problem it would be greatly appreciated.

I had the same issue a few weeks ago. It was the SIM card. I only had the phone for 2 weeks and got a new sim card when I got the phone. It just went bad. Go to a corporate Tmo store and get a new card. They will give you one for free.

I have this same problem with my SGH-T989.
I'm running CM 10.1.3 (Android 4.2.2), and it's vendor unlocked (used to be a Rogers phone) now on the TELUS network.
Data will randomly disconnect, but I still have all signal bars in grey. A reboot will enable it again, or sometimes it just comes back on it's own. I've been to the cell booth in the mall and they've swapped out a SIM card for me, no change.
I also noted that when the data isn't working, my WIFI doesn't seem to either. Modem issue? How can I tell what modem I have and what would be best? I assume CM 10 comes with it's own modem for this phone and when I flash CM it writes the modem too?
thanks for any help.

Flashing a ROM usually does not touch the radio. Newer ROMs(4.2.2 and later) need either the UVMC6 or TLMC4 radio from here:

[Q] ace 2 network problems

Hello
I've just bought a new galaxy ace 2 and I am experiencing some problems.
When I'm using only gsm network type (i think, now I'm testing HDSPA), typically, when I'm logged on icq, mobile sometimes loosses signal and displays there is no service. After few seconds is everything OK and network is back at full singal. This can be seen also in battery usage view, when I'm having always yellow line with thin red places.
I'm now using it with mixed mode on HDSPA and there are no problems with network.
The phone is under warranty, so there is no problem, but I dont have much time and first I would try other solution. I tried to flash it with odin to same fw, but no change. I tried to google it but I didnt find any solution. Could you give me advice?
Thanks for answers

Well the "train" issue is due to the train being like a faraday cage, blocking the various microwave signals, the reason you get a signal on a train is because they have amplifiers to retransmit the signal into the train and vice versa.

...what network?

[SOLVED] GALAXY S3 i747 stuck on edge!

Ok have had this problem for a while now feel like i should try to address it now.
my s3 is stuck on 2g (edge) the frequencies for 3g and 4g ( technically 3.5g or H+)are all supported by my carrier (jamaica - Digicel) i payed someone to fix it a while back and it worked and now it has stoped working again.
when i try to force 4g ( via *#*#4636#*#) i get it for a couple seconds and then signal drops.
also from the 4g stoped working i have noticed my calls dropping more frequently even when data is turned off.
any advice leading to a fix would be greatly appreciated
device
att i747 running 4.3 rooted and stock Samsung rom .
EDIT:
Solved this issue if any one encounters this problem with their device don't hesitate to pm me or reply to hear what i did

downloaded nv reader/writer
downloaded it from here
http://forum.xda-developers.com/showthread.php?t=2374063
then i made a backup of my imei just incase it didnt wrk...dont know how? watch this
http://www.youtube.com/watch?v=CQkUozRhGvw&feature=youtube_gdata_player
came across this in a forum and injected this nv item into my s3
http://forum.xda-developers.com/attachment.php?attachmentid=2297379&d=1380728466
and then turned on mobile data and put my phone in and out of air plane mode and 4g poped up
im guessing that imei backup only works for i747.
this worked for me. my imei wasnt missing but this fixed it.
