[Q] Signal showing 3g.. then 1x.. then nothing

Hey guys, I just recently updated to sense 3.0 and immediately after my phone will show 3g then it will drop to 1x then soon after it shows no data connection. If I try to open an app that uses data like the market it tells me there is no connection, some apps tell me to check and make sure I am not in airplane mode. Then randomly 3g will kick back on for a bit then it will cycle back through 1x and no data again. I also cant tether anymore either.
I reverted back to the stock rom backup (only root no other changes) and now my signal does the same thing. I have no way to get data now and its super frustration.
Things I have tried..
Calling Verizon (solution is warranty replacement)
*228 (does nothing)
Bringing back a known working backup (does nothing)
Restart/Battery pull (nothing)
Putting it in and out of airplane mode (nothing)
I am currently downloading 2 different roms and the newest radio and I will try and flash those and see if it works.
Any thoughts?
Thanks!

No phone signal yet can use mobile internet

I've got a strange problem that I cannot solve or find anyone else that has had the same problem.
I recently updated to Minco V4 and since my status bar has been showing no signal and mobile standby shows 100% without signal yet I have mobile data. I cannot make any phone calls but can browse the internet. No amount of rebooting, airplane mode on/off will work. I've also gone back to both stock ICS and JB where the problem still exists.
My network is T-Mobile and it won't let me manually connect to it but the phone will occasionally register when I select automatic although it doesn't correct the fault. Anyone have any ideas what has gone wrong with my phone?
UPDATE: It seems I can only get a phone signal when select 2g T-mobile network only or connecting to T-Mobile orange. If I untick 2g networks and it connects to t-mobile 3g I can't receive or make calls.

Does your Radio and baseband match?

I installed the linked radio from the MiNCO thread after flashing the rom and discovering this issue yet it made no difference.
I got a phone signal momentarily about 15 mins ago which allowed me to make a short phone call to test it. I then accepted the JB system update from Google and now have no phone signal, just data.

[Q] Signal Issue?

So I've had my VZW Galaxy Nexus since launch, and have absolutely loved it. It is by far the best phone I've ever had, and I've had zero problems with it... except for recently.
For the past few months I've had a problem where my signal bars get greyed out and I can't access anything, even when it shows I have full signal. This will happen on 3g, 4g, and wifi, and sometimes toggling airplane mode on and off will fix it, but most of the time I have to just wait for the connection to come back on it's own.
I've read about signal issues plaguing the Nexus, but I always thought it was just where it showed no signal at all. Am I experiencing the issue, or is it something else entirely? And is there anything I can do to try and fix it other than getting a refurbished phone? I have tried every radio combination out there, and have settled on the latest radios (l515.09 V.FF02 / l515.FG02) and the issue has persisted throughout.
TLR - Phone will often grey out bars and I can't connect to anything. Happens in 3g, 4g, and wifi. Is this the signal issue people have been talking about or something different?

Try getting a new Sim card. I've read on other Gnexus forums. That's good fix for the gray bar issues. other solution take out the Sim card and let it sit for a minute or 2 then pop it back in. Lastly a factory reset.

a signal drop is when your device's antenna looses conection to the nearest cell (tower, mobile transmission equipment) totally.
a data drop is what you're experiencing.
this is on stock rom, correct?

It has happened on stock rom. Right now I'm on AOKP JB Build 4 with the 20120726 gapps from goo.im/gapps.

[Q] Data dropping/freezing after 4.0 update??

Ever since updating to ICS I have been having an issue where my data connection completely freezes or drops. The signal strength icon always shows a strong signal, but the yellow-orange send and receive bars next to the 4G LTE icon stop. During this time I can not receive texts either. I usually just put the phone in to airplane mode and then off airplane mode to restore the connection. I know others have been having this problem as I saw several comments on AT&T support, but no solutions to fix this were listed. If there is another thread please redirect me to that. My phone is completely stock, never rooted or had any customizations done. I have replaced 2 SIM cards and done multiple factory resets. Any info you guys can provide would be great, Thanks!

LTE driving me insane, lose it after switching to airplane mode.

Hello, I am on a rooted stock Jelly Bean Telus ROM with default recovery (I flashed the rooted stock image through ODIN). Every now and then I will lose LTE even though I am in an LTE area. I try to do the trick of turning on airplane mode and turning it off to get the connection to reset. This actually doesn't do anything. HOWEVER, if I restart the phone, I get LTE back with 20 seconds. Once it restarts it can stay on LTE for a long time. Even when I get a call it'll go to 4G and then switch to LTE once I finish.
But here's the kicker. If after I restart it, get LTE, THEN switch to airplane mode and switch back, it will never, ever connect to LTE again. I have to restart the phone to get it back. I've just done a hard reset and the same problem occurs. This sounds completely ridiculous and I've tried everything. Has anyone heard of anything as absurd as this?

Had the exact same problem with a Telus rom, I dont suppose you're on ATT by any chance?. Mine wouldn't connect to the mobile data network when coming off a wifi connection and would just hang in limbo until i switch mobile data on and off. Dumped it and went to a ATT based rom, problem solved. One thing I noticed is that the APN options with the telus rom are different than ATT roms, the apn type in particular

Ask in Q&A or the sticky thread for LTE
Thanks
