For about two weeks I have not seen a 4g connection on my phone. I've tried multiple roms and even going back to stock and still no LTE. I've tried toggling back and forth from airplane mode, taking the sim card, and just simply rebooting the phone but every time it doesn't even attempt to connect to 4G. I've tried both Global and LTE/CDMA settings under mobile networks. I do get 3G with data with no problems. I do have the Network Signal app which tells me I am connected to EHRPD and I seem to be stuck on it. I called Verizon tech support and they told me the only other two things I can do is replace the sim card and do a factory reset. I asked them to send me a replacement sim card so I will try that first.
I have two questions:
1. Is there any issues with doing a factory reset on the stock side considering I'm rooted and have roms loaded on slots 1 and 2. I wouldn't think there would be, but wanted to be safe before I do something like that.
2. Does anyone else have any other suggestions?
Thanks for the help in advance
I'm having a similar issue. Side loaded the JB update, worked like a champ, rebooted a few days later and lost 4G. Verizon has told me to nuke and pave, which i've done multiple times but no joy.
I have the same issue....have you found a fix for it yet?

I have been running custom roms on my droid since the root explot was first discovered, and I have a rooted xoom as well. Last night I rooted my thunderbolt and installed the debloated rom. I don't think it is even related to my problem, as it still worked fine after doing this, but I thought it was worth mentioning. I removed the sim card today, just to prove to my brother that it did indeed have a sim, and after reinsertation, my thunderbolt has not been able to connect to a data network. I do not live in a 4g area, and I have tried reseating the sim several times. I can make phone calls, wifi works fine, but I cannot get the 3g icon, and the browser won't load if not on wifi.. I'm starting to get scared. I can't think of anything else to try. Any suggestions?
EDIT 1: I have intermittent 1x data, but I never get 3g. And when I say intermittent, I mean I get it like right after a call for maybe a minute, then it goes away.

I had this same issue as well when I removed and reinserted my SIM card. When I booted back up I was stuck on 1xRTT. After making a call, they phone locked back on to LTE and everything was good after that. If it still isn't working I would recommend giving Verizon a call. They may be able to reactivate it. I did notice that the problem persisted even though I flashed a couple different roms on the device. I'm thinking it probably isn't a great idea to remove and insert the SIM if you don't have to.
Just an update,
I spent 2.5 hours at the effing verizon store today after spending an hour on the phone. Even after all that time, and giving me a new SIM, they STILL couldn't get my TB to connect to 3g. They said that it might magically start working at midnight for no particular reason, but had no clue what to do (I was actually at a corporate store btw) If it doesnt start working tonight, I am going back tomorrow. I have no idea what the hell is up. I am very tech savvy, and this is just insane. It must be a verizon problem in my area that it wont let the phone reactivate for the 3g/4g
My co-workers phone service got cut off recently, and after it was re-connected, she lost 4G. I had her on Synergy 255 and had the latest radios I found which was CDMA: 1.48.00.0906 LTE: 0.01.78.0906. Even when I updated her to Synergy 262, the problem persisted.
Anyone know what might have happened, I know the recent OTA update for gingerbread has been giving people problems, is it possible the OTA update problem also affected her phone since she was already in gingerbread?
I just put BAMF Forever 1.0.7 on her phone, and it's still only able to connect to 3G, is the problem on verizon's side?
Check your settings in say an app like LTE on/off make sure she is in LTE mode or cdma/LTE

tried to put her on LTE mode only a few time before, and she can only get 1x speed.
Unroot it, return to stock with the full RUU and see if its busted. If it is you probably have a bad radio in the phone...I had to send my first TB back a week after I got it for this reason.....
Customer service was very helpful believe it or not, just make sure you tell them you have already done a hard reset on the phone, done the OTA's and 4G still doesn't work. The will ask you your build number, etc. to make sure it matches what's "in the system".
So just return to unrooted Froyo, do any and all upgrades to get it current, if it still doesn't work you should be able to get a new phone.

I'm hoping I don't have to go there, but it seems I'm not the only one with the problem, since I found some people with similar dilemma on the radio thread.

Sim card
Another idea is that the sim card is dead.
Verizon 4G sim cards can't be reactivated once their deactivated, this happens when you try activate a 3G phone on verizon from a 4G phone, the sim will be dead in 24 hours, I'm guessing the problem may be the same here, once the SIM was disconnected in the system, it can't be reactivated.
Unfortunately to get a new sim, you'll still have to return to unrooted stock to get support from Verizon, but I expect the phone itself is just fine.
Verizon employees are still somewhat inexperienced dealing with these 4G sim cards from what I've seen in stores, so they may have failed to account for that when they reactivated the service.
That seems more likely to me than the phone just happened to break when the service was disconnected.
Did you ever try just flashing another radio? It's worth a try. I would try flashing the radios from the 1.70.605.0 build.

You we're exact on the mark about the sim registration. I told her to replace the sim. And sure enough it worked after it was activated. Glad I didn't I have to resort to going stock and unrooting... She probably would've beat me up...

Wasnt sure where to post this and coulnd't find anything about it so sorry if this has been addressed.
I am going to afghanistan and I am on my way thru kuwait. I activated my global roaming capabilities and got a GSM roaming signal on my Verizon RAZR in Germany and Kuwait so far.
Problem is this.
I have been in kuwait for 5 days now. The first 3 days I had a roaming signal no problem. The 4th day my roaming signal went away and has refused to come back. I am in the same area that I had a great roaming signal at before.
I am able to do a manual search on my phone for GSM networks near me and it finds Zain and Wataniya but when I try to connect they say they are unavailable.
I tried a local wataniya sim card and it picked up a signal right away.
I have talked to verizon, reseated the sim, wiped cache and wiped dalvik no change. Will do a nandroid backup tonight and factory wipe and restore my data to see if that helps.
But I just dont get a signal with the verizon sim anymore. Not sure what the problem is here.
Any ideas or suggestions on things to try would be greatly appreciated.
I will reply as soon as I can as internet is not nearly as readily available here as it is in the states and I will be on a plane to afghanistan in a couple of days.
I am just hopeing I can get this issue resolved or atleast come to the conclusion that my verizon sim if fried before i leave kuwait.
Thanks for all your time.
Imho, this issue has got nothing to do with razr. The problem you face must be because your original carrier may not have roaming tie-ups with the carriers you are trying to select. Or the local carriers in Kuwait may not be allowing foreign SIMs.
You could try putting your SIM in someone else's phone to confirm.

I think Sims can go bad when in roaming. If this is the case, you have to change it. It happened to me once.

Actually it had nothing to do with the sim or the carriers around here. I tried to every possible troubleshooting step that I could with no luck.
So after I posted this I ran a nandroid backup and hit the phone with a factory reset then restored only my data and the signal has returned.
There must be some file that got corrupted or got the wrong config during a transition between one of these roaming towers at some point and the factory reset fixed it.
I am back up and running again and all is well.
On a side note verizon tech support is utterly useless.
Thanks For the replies!
My DNA just has the Voice service after connecting to WiFi over night. The first thing I need to do after leaving home is flight mode on and off to get the phone back on the carrier's network data. It is annoying, Am I the only one here?

I get the same problem. I have also experienced "preparing sim card" messaged several times. I hope the OTA update helps, I have not had the chance to install it as I am currently studying abroad.

Have you tried in gsm only mode? I have same problem and preparing SIM card issue doesn't come up in 2g mode. I was reading this kind of issue is produced most likely by a faulty 3g antenna.

I experience this problem frequently too. Not sure if there really is a fix for it. Toggling between airplane mode works for some people, reseating the SIM card, gently erasing the back of the sim card, applying 2 layers of tape to the sim card tray to keep the card seated appropriately, exchanging for a new SIM, putting phone into airplane phone and removing sim than replacing sim card, remove sim card than boot into recovery and clear cache and dalvik, etc.. yes I've tried most of these but to no avail. The OTA update may have helped a little I am not sure. Most believe it is a hardware issue that really can't be permanently fixed. If anything else is found let us know. Such an annoying problem that totally ruins this amazing phone.
There's different issues being discussed here. It sounds like you're having the issue where you need to toggle airplane or network sometimes when switching between networks or from WiFi to mobile data.
It's not device specific, there's some decent articles on it and in the early days we thought it was a Verizon issue. But it's actually a Sprint problem too I learned on accident when I was trolling their forums.
When the network is activated, on a device with a SIM card on Verizons network, the preparing SIM notification is actually describing a process very similar to *228 back in the olden days before LTE that was done when first activating a device on the CDMA network. The LTE network is different in that everytime it connects to the network is does that SIM activation process.
I know on my networks here, there's a changeover in one place it happens about 50 percent of the time.
If that's what is happening to you and toggling airplane fixes it, I think it's an LTE/network symptom and not due to a faulty device.
However I have a device I'm about to warranty with a hardware failure I'm thinking. It gets data great but absolutely no voice ever, never had an incoming call or anything. Or made an outgoing call in the month I've had it. It doesn't bother me I didn't buy this thing to talk on, but I'm donating the device so I'm going to have it fixed.
Anyway, from all the OP has posted so far, I'm not feeling like it's a hardware or device issue, however as more info develops that opinion may evolve.

U r the man Charlie. I am having an identical issue as op. And based on occurrences relevant to location it seems that this is only an issue when under 4g service-atleast for me-. Toggling airplane mode reactivates SIM as u said and restores full functionality. However, I have noticed the time needed to pass for said issue to reoccur is significantly shorter unless a full restart is preformed. If fastboot is enabled the issue persists. My question is this; if this is a network issue -which I'm sure it is at least in part- what software wise -if anything- could be going on a full restart fixes?

I'm a gsm user and I'm having the issue in a non 4g lte network. I have preparing SIM card every couple of minutes. If I toggle to gsm only mode everything is perfect, not even a single issue. Looking to the logcat, when the error comes up, it shows a message about ICCID number doesn't match stored one and then invalid radio technology. Is this software or hardware? I'm really confused. I've already tried everything from software side, kernels, radios, roms, RUU to stock.

I've searched and didn't find any thread with this kind of issue specifically. I have a Verizon Galaxy S4 that doesn't seem to like GSM SIM cards; it looks like it is not GSM unlocked. I have tried every trick to get it to switch to GSM but it doesn't. I have flashed the same version firmware it came with (ME7) just to be certain it's factory restored, and also updated to MK2, yet no GSM. It sees the SIM card but doesn't show a signal, even when I manually switch to GSM/UMTS. I have programmed a CDMA number on it manually then tried the GSM switch again, yet no GSM signal. It sees CDMA signal fine though and can even make calls on CDMA. I even had to check the MEID/IMEI and it came back clean so I'm just surprised at all this. I have done this before successfully on a Verizon S3 and it worked well, how come the S4 has refused to work on GSM?
Please help, anyone?
Did you input APN's?
I thought APN settings had to do with data. I will do that now. I'm willing to try anything now.
Thanks.
I am having the same issue with a couple s4s from verizon as well. Checked the IMEI/MEID and they come up clean but they will not catch a signal with a gsm SIM card. I have tried several active AT&T and T-mobile SIM cards in the phones with the same results, no service/signal. Very strange as I have never had an issue with verizon S4s working on AT&T or T-mobile. The weird thing is that with a verizon SIM they catch signal and 4G just fine. Toggled GSM/CDMA and put in APNs and still no luck. I'll keep trying to work this out but right now I am stuck.
I had the same problem here
My GT-I9505 Rom Stock 4.4.2 ZTO(Brazil) had the same problem about signal problem.
Everytime i lock my phone (turning off the screen), by the time i light it on (lock screen), immediatelly my phone turns the signal to "No service".
In this time, i need to wait 1-2 minutes to the phone turns okay. Just wait.
I search for a lot of solutions and didn't find anything.
Notice too that the problem appears only network 2-3g. 4G didn't have the problem.
I solved this problem after Lollipop update. The problem simple dissapear!
(Sorry my bad english)
