I just started having this issue, i can't connect to any data at all, i have tried battery pulls, using restart connection, running different roms, using restores where everything was working, doing a full wipe and then installing a new rom, but still no luck. Should i try just a factory restore? i also read that taking out the battery, then take out the sim card, booting the phone up with out the sim card in, getting errors and then shut it off and then put the sim card back in works, but im not sure which of those to try, any advice?
when that happened to me i did a factory reset and it worked afterward
Check around first, see if Verizon is having problems in your area. I know recently places have been popping up with sporadic outages.

But isn't installing a rom and wiping the data and cache the same as a factory restore?
I had this happen to me earlier this week. When I called Verizon support they told me that towers were down in my area, they told me the same when I called back the next day. Meanwhile, others who own the TB seemed to be having no issues. Finally I took my phone into a Verizon store and they are shipping me a replacement phone. They would not swap my phone in the store since I was a whopping 4 days beyond the 14 day return window...but, I digress.
The one workaround that I found in the meantime is to switch your modem settings. Dial ##778, select Edit Mode, enter 000000 as the password and select Modem Settings. Select Rev. A and choose Enable. Press your menu button and select Commit Changes. Your phone will reboot and you can use the LTE On/Off App (or just dial *#*#4636#*#* and choose Phone information) and switch the radio to CDMA Auto (PRL). That enabled me to have 3G data, though it seems extremely slow relative to 3G on my OG Droid. But, in a pinch it seems to work.
One additional bit of advice, in case you are running a custom ROM. I was running Virus ROM and ##778 would crash whenever I tried to run it. In order to swap the modem settings, I had to flash back to stock and make the updates, then flash back to Virus. I don't know if this is specific to Virus, but just an FYI.
Just tried on das bamf and worked fine (##778) must just be virus.

Thanks, that got my 3G working, will i still have 4G with it on that setting? or do i need to switch it back to use 4G or do i get the Lte on/off app?
*#*#4636#*#* and tap on phone information and go to the box that says "CDMA+LTE" THATS default 3g and 4g and for only. 3g is auto prl

You won't get 4G on that setting, it turns the 4G radio off entirely. You would need to switch back to the CDMA + LTE/EvDo auto or LTE mode settings to get 4G. Ultimately, my issue ended up being a defective phone. You can try to wait it out and see if you get 4G back later, but you may just have a faulty device.
If that is the case, just remember to follow the instructions that jcase posted in the development forum to get your phone back to stock with s-on before taking it into a Verizon store. If you bring a rooted device in, I suspect they aren't going to honor any sort of warranty.
My phone had this problem too... turns out when I went into a 4g area the mobile network box got unchecked in the wireless & network settings.
I use the "verify with multiple devices method". I am tired of the standard VZW "towers are down in your area" bs answer.
If another tb, xoom, and bb have service and my tb doesn't, that tells me something is wrong.
I have a feeling that there is something seriously wrong with the network (implementation or backend hardware) that is causing this with 4G devices. Either that or the tb is to blame entirely for Verizon's 4G issues...... /rantoff..... LOL

Was having issues earlier today with 4G. The connection and signal were good, but no data would download. The white up arrow would light up, but the down arrow never would. It was like that for about 4 hours. It's working great now and speeds are disgustingly fast.. maybe VZ doing some maintenance?
EDIT: THis is in San Diego.

Factory Reset from bootloader worked for me. I had the exact same problem. Tried everything that was suggested, but no data still. Only enabling Rev. A worked.
Thanks for the help, the problem I'm having now is I got 3g but I can't get 4G back, I have tried to switch my settings back to get 4G using LTE on/off and by dialing the number, and I have had no luck, in those menus it tells me service type LTE but it is disconnected, and I get no data or 4G symbol in the status bar, so I'm confused if I maybe messed up a setting or what, so should I just try a factory restore via the bootloader and see if that works? Any other suggestions ?

I would try the factory reset from bootloader, but I was on the stock ROM when I did it. So I don't know if that would matter or not.

Just to reiterate, my 4G never came back. The phone was just broken. It sounds suspiciously like you are having the same issue. Maybe there is a manufacturing defect that makes this issue more prevalent with this phone right now? If you are in the 14 day return period, set your modem and radio settings back and get into the store ASAP to swap the phone out. Otherwise, call customer service and have them replace the phone. They will overnight you a new phone if you complain enough.
Ok I was looking through my modem settings after dialing ##778 and I had changed the rev a. Setting to enable, that got my 3g working, but what is eHRPD is that would I should have it on too have 3g/4g? But everytime I have tried setting it to that I get no data so is that the setting that is messed up?

Well I have this SGS4G and I updated it to kd6 and it messed up the network. I almost never got a signal (it would show the circle with a line through it). I flashed it back to KD1 rooted and now it works but it only gets 4G network. Whenever I get out of range of a 4g tower and the phone switches to GSM it gets no network. Is their anyway to fix the radio firmware on this?
Please use the Q&A Forum for questions Thanks

Go to the market and download an app called GPS Aids. Go through the initial set up with it, then under the Tools menu at the top (not the actual menu name, but it's similar), then scroll down the screen until you see an option called Hard Reset. Give that a shot. Bear in mind that you will lose any data you have on the phone when you do it.
Kd6? Never heard of it... Have you tried flashing a different modem?

KD6 would be the gingerbread update. Phone was fixed with a new sims card even though we got a new sims card when it was bought, turns out it was one of the older defective ones

For future reference - KJ6 was the GB update.
I have Verizon Samsung Galaxy s3 and used phone info app to turn on only 3g selected (CDMA auto PRL) but I'm not getting full signal when I'm close to a tower I get maybe 3 bars. Am I selecting the right option in the app or should I select something different?
From what I have read, that would be correct but on another note.... I haven't seen 4G all day today and my 3g is only 1-2 bars since starting my morning...

you have to reprovision your device with this dialer code: *2767*3855#
this wipes data so have a backup ready...
I have a verizon gs3 that is rooted, running beanstalk 4.4.251-20140301-d2lte. I can't get LTE to work correctly. I can get LTE to turn on if I change my 'preferred network type' to LTE/GSM/WCDMA, but then I have no verizon signal (voice signal). When I have it on 'global', I can get 3G and verizon signal, but never any LTE.
This has been going on for quite some time. I've switched between all of the 'preferred network types' but its always 4G and no cell signal, or 3G with cell signal. I used to be on CM 11 nightlies, thought that might be the issue. I switched to Beanstalk, but have the same issue. Just yesterday, I updated my firmware from here: http://forum.xda-developers.com/showthread.php?t=1788313
Is there something obvious that I'm missing?

I have the EXACT same issue, so you're not alone! Unfortunately, I have no answer for this either.
I was running CM11 (just the stable releases), started noticing lack of LTE a few weeks ago, decided to give SlimKat a try. The ROM is damn near flawless besides this LTE issue. I could actually never get it go into LTE mode through the normal settings, it would always fall back to 3G (and I'm in the middle of a capital city where there's plenty of 4G coverage). However, if I did that *#*#4636#*#* trick to go into testing mode, I could force it into "LTE Only", at which point the phone would be in LTE mode, and enjoy the blazing fast data speeds I pay for .... but can no longer make phone calls.
Anyone else out there experienced this or something similar? Any suggestions would be greatly appreciated.
Thanks!
After doing some research on it, I decided to flash back to stock and unroot. After that, I still could not get 4G, so I took it into the verizon store. I told him the problem, and that I had heard that it needed a new sim card. After doing some simple test, he burned a sim card for me and that did it! I'm thinking that soon after I flashed a CM11 nightly (a month ago at least) I dialed *228 to update my cell coverage. I think that might have fried it. I have limited knowledge on this topic, but I did read somewhere that dialing *228 on some custom roms is not good.
It would be nice if you could take it in to the store without flashing back to stock, but I'm not sure if they would go for that or not.

Ah!! I dialed *228 too! Ok, that's gotta be it. Thanks!
Recently got a i727 with stock jb. First time with lte and was impressed on the speed. Flashed Philz cwm and cm 10.2. Everything works great execpt i can only have 2g on mobile data. If i deselect the 2g networks (saves battery) i lose all data connections altogether, regardless of the network i try to put it on (like lte/gsm/wcdma). I can still make voice calls and recieve sms but no data. From there, the only way to get data back on is to click 2g networks and start wifi. When i turn wifi back off the 2g starts up again. I understand att being RATT-locked, but wouldnt that mean i cant select my network, not limit my lte? Could this be a radio issue or something in the kernel? It runs the i727UCNJ1 radio, wich is the latest. LTE worked on stock JB, but wanted CM10 so i could use it as needed without killing battery. Any help would be greatly appreciated. Thanks.

Philz touch 6.48.4 (cwm v6.0.5.0)
CM 10.2.0 (4.3.1)

I don't think you mentioned what network you're on. If you're on anything other than AT&T, you'll probably have to flash a different radio. There are a few listed in this thread:
http://forum.xda-developers.com/showthread.php?t=1785999
If you have service with AT&T, I'd suggest that you go into Settings/Mobile Networks/Access Point Names and check the APNs. If you already have some APNs listed, make sure that the "phone" APN is selected and not "pta." Or you might need to manually put in a new APN.
Sorry, I am on att. And yes, after researching I did try to flash to two different radios. The ucmc then the rogers. I even found how to put in new apn's but still nothing. Strange thing is in the mean time I have flashed slimbean and reflashed cm and both still had 2g only.
So last night I flashed the stock jb with cwm from the sticky and now 4g is back on stock like it was before I put cm 10 on the first time.
I like the ui on cm10 but whats the point of an lte phone if I cant use lte? Now the trick is finding why it would only use edge. If anyone has insight im more than open.
Edited to give a big thanks to mohan_kr for the info ive been reading.
