There are quite a bit of threads pertaining to this particular issue, but most of these "fixes" require the files to have been backed up and simply be restored. I have no idea how I lost my service since I've always flashed new ROMs with a clean slate. A back up would be buried in the external sd card just in case. This time, I installed the N3BULA ROM v3.6 Android 4.3. I assumed the modem and other prerequisites were common since there were no links to obtain them, though I did seek out the modem firmware they mentioned. Once I booted, I had a circle with a line through it instead of the 4G LTE symbol or the bars. I CANNOT CALL, TEXT, NOR ACCESS DATA!! I would call it a brick, but everything else works just fine! I've done MANY methods to no avail. I've tried different stock ROMs, all did not want to activate and even when I reverted back to the exact ROM back-up I made prior to N3BULA, it had no service. My SIM card is still registered with verizon and from past experience, I KNOW a new SIM card ain't gonna help. I've been reading about a lot of **** coming from the 4.3 updates, but I never expected something like this...
HELP ME!!! I DON'T HAVE MONEY TO BUY ANOTHER PHONE OUT OF CONTRACT!!! (I have unlimited data still ^-^)

My Samsung SGH-T959 Will not connect to the T-Mobile GSM network. All other functions appear to work OK. The phone worked well enough until I needed to use it in Britain last week. Until then, it was stock from the store, locked to T-Mobile USA.
I needed connectivity so I unlocked the phone and used it with a Vodaphone (lebaru) pay-as-you-go sim. At first it would not register with the provider, but I gave the phone to the agent (some Arab guy in a small shop...) and after they kept it overnight, it worked. On returning to the US I put the original SIM back in the phone. Now it won't register with T-Mobile. Sometimes it finds ATT towers when I scan for network providers, sometimes it does not. It never sees T-mobile.
I have verified that it is unlocked, and done a hard reboot and washed away the internal Flash storage. The behaviour does not improve. I have tried two known-good SIM cards.
I have read many posts that seem to indicate that others are having similar problems, but I haven't seen any answers (or even explanations).
Can anyone suggest a solution?

Ok, I guess that I'll need to use Heimdal, as I don't have windows. But where do I get a 'stock' image to load? If what I have is not stock, how do I know what it is? And if I come to the point of having to load alternate 'ROMs', which do I choose. There seem to be so many caveats.
What I find really perplexing is my phone's sudden inability to lock to the tower corresponding to the sim provider I'm using. With other phones and modules I have used over the years, this was ever an issue. You put in an ATT sim, the device tries to connect to an ATT tower. You put in T-Mobile or Vodaphone, then it tries to connect to the corresponding resource. It almost seems as if there is a small hidden file somewhere in the bowels of the beast that overrides the sim's preference.
Still trying...
Ok, after much wailing, flailing, and gnashing of teeth, I have sorted out more of the vocabulary of this forum, hopefully attached it correctly to the relevant concepts in my head. I feel that I am making progress of a sort. I have also installed Heimdall under Linux, Odin under Windows, Kies and a variety of minor tools. I have tried them cautiously, but avoided any rash actions. I believe that I will make a unbricking cable for good measure.
But my phone still won't connect to the T-Mobile (US) tower. Scanning for 'networks' only shows ATT, and I'm pretty sure that I can't even talk to that using an ATT sim.
My working theory is based on the events that got me to this point (but still far too little knowledge about my phone) and goes as follows:
When I had the phone unlocked, this was done properly, but my T-Mobile (US) 'MODEM' (which I assume to be the signal processor code that controls the physical layer radio interaction) was not able to negotiate a session properly with the Vodaphone (UK) tower. I took the phone back to the person who unlocked it, and he/she/it realized the problem and updated that part of the code, allowing me to connect with the 'network'.
I never mentioned to the phone-unlocker that I only planned to stay in the UK for 10 days. It didn't occur to me that upon returning home, I might encounter the flip side of this problem. And if he/she/it happened to think of this possibility, he/she/it figured I'd be well out of his/her/whatever hair by the time I noticed. Which I am.
So my operating assumption is that I need to reverse the initial modification of my firmware, restoring the initial functionality to the 'MODEM'. I have yet to find a trove of alternative 'MODEM' code, but responses to queries by others seem to imply that one exists. I am reluctant to attempting to flash the device back to the original state, mostly because I am not sure what that state was. I've downloaded a bunch of stuff (i.e. Odin + .pit files) but I'm nervous about whether they are really the right ones for my phone.
Can anyone tell me if I am on the right track?

You should download the AIO Vibrant Toolbox since it have all the instructions and files you need to revert back to stock. Its pretty easy.
Instead of typing so much, odin back to stock. Man I hate fast typers. /crazy.flailing.arm.tube.man

Hello all,
I have had no data connection in the last few days. solid signal, but no data. i have done almost everything i can do and still the same result. switched back to Rev.A and i can get 3g "ok", not sure whats up. Any suggestions? I also reflashed the Mr2 radio and no change.
Another thought is my SIM card might have taken a dump. Id be willing to take it into verizon and get a new sim but dont want to unroot, revert to stock. got way to much going on with my phone to just start from scratch again : ( just so i can "try" if a new SIM would work. what would happen if i took my rooted thunderbolt into a verizon store for a new SIM card?. Would they Deny me service?or put a note on my account stating i have rooted and voided my warranty?. Just curious as to what would happen. they would deffidently notice right off the bat because of my sense 3.0 rom, kernal, gingerbread, signal icons,lock ring,signal bars, spash screen, boot animation and sound, etc...
need help guys! thanks in advance! : )
Well I know you said you don't want to but just make a nandroid backup before you unroot and stick it on your pc for safe keeping. Then when you are re-rooted just wipe everything and restore the backup and you are EXACTLY where you were before. Plus with Revolutionary re-rooting takes all of 5-10 minutes.

Talk to the guys there. Get a feel for them... The guys at the shops near me couldn't care less about a rooted device. As long as the software isn't the issue, which a bum SIM shouldn't be, they shouldn't really care. I'd feel them out a bit before assuming unrooting is a must. You might get lucky.
I will send this thread up. This is exactly the problem I am experiencing. The Thunderbolt has perfectly good network signal but data connection is not working. It complains about "SIM card not found" when entering the Settings and APNs. The SIM card is detected by the device otherwise, it's possible to save contacts to it and retrieve them. But 4G data is completely dead.
I visited a VZW store yesterday and received a new SIM card but the problem is still there. I have also tried to reflash to the latest leaked radio without any solution.
The ROM used is the latest Synergy Nightly.
I begin to consider the possibility of restoring the Thunderbolt back to stock and get a replacement but it would be good if this problem can be solved.

[Q] "Can't connect right now. Try again later." or equivalent in stock, CM9 and CM10
Hi folks! Needing some help, please.
I've googled my problem a lot but couldn't find any working solution. Below is the detailed history.
I have recently bought a Samsung Galaxy S3 GT-i9300, cut my previous SIM, and used it for about four weeks with no problems. During this time, I rooted my phone, backed up the stock ROM, installed CM9 and afterwards CM10.
About a week ago, while using CM10, I switched off airplane mode after about nine hours and the signal power meter was empty. All the services related to my carrier (SMS, 3G, calls) were inoperative. I rebooted the phone, tried removing and reinserting the SIM, with no success.
I tried flashing the previous backups, also with no success, but noticed that while using the stock rom, the signal meter was full. This prompted me to access "Settings > Wireless (...) > More... > Mobile Networks > Network Operators", where to my surprise all the available carriers were listed. I did the same check in the rural area of my town, where I know my carrier does not work, and the cellphone correctly detected only the other three carriers.
These symptoms led me to believe that my cut sim could be the problem. I got a microsim from my carrier, but the problem persisted.
After this, I assumed the problem was software related, googled it and found some recommendations:
Complete wipe and backup restoration: this was not successful with stock, CM9 and CM10.
Complete wipe and stock ROM re-installation with Odin: also not successful.
Modem flashing with Odin: also not successful.
Firmware flashing with KIES: I put the cellphone in download mode and made the firmware recovery procedure from KIES. Also not successful.
Restoration of efs folder and IMEI related issues: I did not have backup of this folder, but the symptoms related to the problem in the posts I found always included the absence of IMEI. When I type *#06# in my phone, I can correctly see my IMEI, so I discarded this possibility. My carrier also informed me that my IMEI is not blacklisted.
I thought of getting a new microsim to rule out any SIM related issues, but still haven't done it.
Information regarding my phone:
Phone model: GT-i9300
Baseband version: I9300UBLG2
Firmware vesion when on stock (from KIES): PDA:LJ1 / PHONE:LI2 / CSC:LJ2 (ZTO)
Could someone please help me? I still have not tried the EFS folder troubleshooting, but the procedures I found were related to problems that did not show the same symptoms as mine. Do anyone have any suggestion? Please tell me if any more information is needed.
Thanks!
Why not just get a micro Sim to begin with....they don't cost anything and it saves a whole lot of hassle. My guess is the sim reader is damaged....IF and WHEN you decide to get a new micro sim, if it doesn't work then that could be the only cause and the service centre your only option. Seriously dude, next time to save yourself hassle....go an get a micro sim from your carrier, I wouldn't even think about hacking away at an old sim because I can't be bothered to walk to a Vodafone shop.

I have just come back from the carrier store, where I got a new SIM, and the issue persists. I also double-checked any IMEI blocking or problems with my services, and everything is ok.
Coincidentally, a Samsung consultant was around. He checked my phone and talked to Samsung tech support describing the issue.
They do not think it is related to the cutting of the SIM card for two reasons, the first being the ability to locate the carriers, the second being the fact that a visual inspection of the slot and the scratch marks on the SIM card do not indicate a broken or bent contact.
Obviously, he recommended that I send my phone to an authorized Samsung service center for maintenance.
I am still inclined to think it is a software related issue. I will, of course, send my phone to Samsung if it is case, but in the meantime I would like to try new procedures to bring back my phone's ability to connect to my carrier.
Suggestions?
Thanks in advance!
An additional information:
I tried checking my sim through some apps, to confirm there is no damage in the contacts. GalaxSim Unlock is able to detect my sim and correctly show my phone status as unlocked.
Any suggestions on tests?

Hi!
I bought S939(not completely new), which from what I understand is not a device that's created for the European market. In order to make it function, I believe that the device was rooted\modified. Now, I can perfectly use it to go on the internet, make photos ecc, but when I put my SIM , I'm unable to "catch" the network of my provider. A message "Can't connect right now. Try again later." appears. I can save numbers on the SIM, for example, but unable to register on the network.
Also on the main screen, I can see writter "Invalid IMEI".
Thanks!

Hi,
First of all to all the people that have contributed to all the subjects that I have read in the last couple of days, wow and thanks. Without your guys experstise, illiterate mobile phone people like me could not do a damn thing on their mobile phones.
My problem, I have a Samsung Infuse 4g with gingerbread which I installed through Odin with all the info I gathered reading post here. When the problem occurred of no network access, the phone had the stock froyo firmware and that had been working very well until now.
I cannot get data at all. I can get on wifi, send calls and text messages. I tried changing the mobile network access points and nothing. One thing that I did notice after reading all your post, was that my IMEI is a bunch of symbols, diamonds, question marks, etc.. but is not numbers like it should. The issue started with the stock firmware (froyo) and continues with GB. Another thing is that I have never backup the system at all, I currently cannot find an EFS folder, even after installing RootExplorer.
I dont put all kinds of fancy utilities on the phone, the only one there is Golf app. This just happened out of nowhere. The phone is not even a year old which I got from ATT. You can say, send back to ATT for warranty! I am a Soldier stationed in Germany, because my account with ATT is suspended until my return to the US, the warranty does not cover the phone. In the end I am screwed anyway since I changed the firmware to GB and it is rooted. My questions are;
1. Is it possible that I dont have an EFS folder?
2. The lack of EFS folder constitutes to an unreadable IMEI?
3. What can I do to fix it? Is there a dummy guide to fix this?
Thanks a bunch!

Hi an update to my issue;
Today I borrowed a sim card from a friend and the phone was able to get data + all the other stuff, calls, text, etc.. My IMEI is still as a bunch of symbols like previous. I got another SIM card from the phone company but still waiting for activation.
I heard that the Note 2 is a world phone. My question is this. Can I purchase a phone from verizon unlock it, ship it to my wife in Afghanistan (she has GSM service) and install her sim without issues? The reason I ask is I am not sure if she is good at changing settings because she is kinda used to an iphone.
When she gets back I would also like it to work on Verizons network because that is the service that we have here.
Thank you for any information you can give me.
For voice and text, it should work out of the box as the Verizon variant is unlocked. If you want data though, you need to do a little work as Verizon wants you to use their global roaming so they left out the APN data. Below is a link to that process. Alternatively, some of the custom ROMs (like Beans) add that in for you. Hope this helps.

You could just program the APN settings, etc before you ship it to her.
If it was me, I would get the phone... unlock it and install one of the stock based roms (beans, cleanrom, etc)
Configure it to her network, her email, etc.
Flash a nandroid of it using clockwork mod or twrp onto the sd card you are sending to her, and a spare smaller one just for that. Take a couple of pictures of how to restore a nandroid and print them out.
That way if for whatever reason something goes wrong with the phone that isn't hardware related, she can flash it back to a working condition.
(I say a spare card also just incase the sd crashes on her at some point)
It is super easy, so if she isn't that confident around screens normally this should work fine.
What carrier does she have?
We can look all the info needed up with the name of the network, etc.
If she doesn't have anything already, then afghan wireless sold by telestial is a decent affordable provider.
