No cellular network "Mobile network not available" !!! - Galaxy S III Q&A, Help & Troubleshooting

I have galaxy s3 i9300 and my problem is no mobile network on my phone so i can't make calls or even open mobile data.
What i did:
I was using CM12.1 android 5.1.1 everything was ok for months but i faced a problem after that time which is "can't open mobile data" i thought that the problem is from the Custom ROM which is not stable, so i decided to downgrade to the official/original stock ROM android 4.3 Smamsung Career, but the issue still existes or it became more deep i don't know what's wrong with it. there's a signal of network connection but when i call it says "Not registered on network". I did the network settings and search for operators automatically but it didn't work also. at the end (currently now) i decided to back to the custom ROM but the problem still there so i don't have no cellular network or data mobile plan.
What i think:
I think that the EFS partition touched Note: i still have the IMEI
So please can anybody help me?? i'm reallyyyy neeed heeeelp

I was wrong my s3 was bricked and it is not the EFS partition that has been touched "beacause the IMEI still there" but the problem is that the Serial Number i have it BUT when i updated to cyanogenmod the OS gives me a wrong serial number so that's why it told me "Not registered..." so i'm needing to inject the true SN in my device. So how can i do that with Z3x Box? thanks

Solved "Your SIM card does not allow a connection to this network"

Hello Everyone, I am using Samsung Ace s5830i and since yesterday I am not able to make any calls, when I try to call a number it says "Mobile Network not available" but I can see good signal strength and I am also able to use GPRS. In the notification area it says "Emergency calls only".
I went to Settings -> mobile networks, when I try to manually select my operator(TATA Docomo, i'm from India) i get the error "Your SIM card does not allow a connection to this network".
I have removed the sim card, inserted in another mobile, it works fine. When I try try to insert a sim card of some other operator into ace I get the same errors listed above.
These are the things that I have tried.
1. Removed the sim card, battery inserted them back and restarted the phone
2. Restored my Nandroid backup
3. Complete factory reset
None of these worked and still I get the same error.
Information regarding the phone:
Model- Samsung Galaxy Ace s5830i rooted with CWM 5.0.2.6
Android version - 2.3.6
Mobile network type - GPRS
Network- TATA Docomo
Signal Strength - -90dBm
Service state - Out of service
Mobile network state - Disconnected
IMEI - Unknown
I have called Network provider they say fault is with the phone.
Any help would be really appreciated...

you have lost your IMEI... u'll need to flash stock firmware via odin!
see this thread for procedure!

Re: Help "Your SIM card does not allow a connection to this network"
Just for the knowledge, what may be the reason for losing imei and does flashing stock rom retrieve my imei.
Sent from my GT-S5830i using xda app-developers app
possible reasons are many...i don't know what files did you flash? (Rom/kernel/scripts)
Cronmod script is known to have this issue...did you flash this script?
Flashing stock rom with odin will give back your imei!
What's your ROM/kernel? and what scripts did u flash?
Re: Help "Your SIM card does not allow a connection to this network"
I am using stock rom. No i didn't flash cronmod script. I'm not sure but i think problems started after installing Online Nandroid backup tool maybe it has installed some scripts, i'm not blaming the tool it is fanastic app to make nandroid backups.
Let me flash custom rom, hope problem goes off.

lost network help

Well after installing a rom and after i inserted the sim pin it poped up this http://prntscr.com/yl5bv and i thought to insert the pin again and i did that few times also tried to enter 12345 etc... and after that i have no network, i restored the backup but didnt helped ,
itried almost everything i relocked the bootloader-unlocked it again, tried different roms and kernels, flashed with seus and nothing helped, as i said only at that rom(touchwiz rom based on fxp 210) it pops up the window to enter the sim network unlock pin ,
on any other rom doesnt, the signal is full and when i try to call it says no network registered
i tried also other sim cards and they either dont work
So does someone knows what to solve this issue or i must go to service center, and my phone is sony tipo st21is
You will get the best help if you visit your nearest service center. I read your post but cant figure out where the problem lies. Sorry . I hope your problem will be resolved by the experts there. All the best bro..
what the Baseband version in the about phone column . Itz dude to wrong baseband. check
Are you still receiving signal? Other than the comments above, you might also want to check the IMEI. Blocked IMEI could also be the reason.

bro i also have this full signal but no service problem it is due to IMEI no. check your Phone IMEI and match it with your phone IMEI on the back behind the battery (Or go to settings -> system -> Device Information -> Identity and IMEI is listed at the bottom.)

Not registered on network, again

This thread is outdated and not related to the new problem with EFS coruption. Solutions proposed here wont help you if you lost your network after downgrading a ROM from MF6 to earlier.
Ok it's not the first thread about this but no one seems to have an answer. I'm trying again.
I flashed a custom ROM on a friend's phone i9300. After the flash the phone keep saying "Not registered on network". I tried everything I know.
I changed modem
I changed ROM (3X) (with full wipe)
I returned to stock
I installed GetRil (changed the baseband)
I installed Galaxsim (phone already unlock)
when I try to set the APN I get a message "registered on network" but when I do a phone call I got "Not registered on network"
Is there anyone who knows any way to solve this problem?
New sim? What all works?

Get a new sim from your carrier. Either your sim tray is broken or your sim card is. Sim card is cheap/free to replace so try that first.

sounds like (both of you) your EFS folder is corrupt - the only way i've read of repairing it is to have a back up. service center for repair is the only option AFAIK.
The IMEISV means nothing, don't even worry about it. Know what you're talking about before you blurt out crap.

Usual suspects .
Sim you tried another .
Sim carrier unusual to be damaged .
IMEI wrong .
No phone number details standard with many roms .
Network details not entered or incorrect or wrong CSC .
Wrong modem unlikely .
Best to restore phone to original firmware .

First I restored the phone with the nandroid backup I made just before flashing. (still not register on network)
Then I restored the phone to stock Samsung with Odin (still not register on network)
The IMEI is still there(most thread I read with this problem people lost their IMEI)
The phone can connect to the network because it can retreive the time from the network.
If I make a network operator search it finds China Unicom(This is my sim card) and when I choose it it says "register on the network" but as soon as I try to call, I get the "not register on network" again.
I thought the IMEI might be block as it might be a stolen phone but I made a search on two IMEI database and it says CLEAR.
I flashed 3 Asian modems( I used to have a S3 I know the XXELJ2 was working with my sim card) and same result.
Have you tried flashing a different modem to your device and reporting the problem to your provider.
May sound obvious but the provider's logs may clearly show what is wrong and they can report it back to you.

anyway, tried this metod too now, and still the same ~
Hey guys, had a very similar problem to kremata (everything in EFS folder seemingly ok (IMEI and S/N were fine)), and for me it got fixed by applying Azira's Patch ( http://forum.xda-developers.com/showthread.php?t=1918601 ).
However this solution only works by rooting and if you try to return it to stock it will reverse to being a 500$ PDA sadly.
In any case, the phone is now fully functional (calling/SMS/mobile data).

[Q] No network - Samsung Galaxy S3 i9300

Hello guys,
I`ve been watching all this topics for a while cuz I have some problems with my Galaxy S3. I`ll tell you what i did.
All worked fine, had the 4.1.1 official rom + root, then i wanted to go to 4.1.2 so i flashed an UK stock ROM. After that i kept getting the "Sim has been removed" error need restart bla bla.. so i search all around for a fix.. i changed 2 SIM cards and nothing. Then I flashed a Poland version 4.1.2 Stock. That version was better but I encountered the "Call ended" error.. calls would end after 3-4mins or i could not call at all. Then i flashed (and this is when the problem started) Stock Vodafone Spain and got "No network". I must say my IMEI/ SN all are intact.
Then I patched only radio modem from the UK ROM with Odin, but with "PHONE" option (i know i did wrong).. i wanted to change only the modem and it worked cuz i checked with *#1234#.. but from that moment not even one ROM has worked in showing me the network. On About phone says "Network: Unknown". Sometimes it connects to Vodafone but when I try to call says "No network service".
Now my phone is in second service and they can`t make it get a network on. They tryed the neverlock thing but i think was already unblocked.
I tryed rooting and using this Ariza. and were 2 versions there.. I tryed v5 only and didnt worked.
I tried the ##72786# and I get the following message: Connection Problem or invalid MMI code (found somewhere that for this code i need to have Wifi on to work?)
Now i`m thinking to get my phone back and dunno reflash with a good .pit file ? or just reRoot and try v4 Ariza.. I`m really sad, it`s been 5 days and I can`t think on nothing else to do.. I even called Samsung official service and they said to send it to them.
If you have any idea, pls need help. tnx
Check your IMEI is the same as under the battery .
Samsung will reject warranty .

you are right.. IMEI and SN are not the same.. pff what to do now?
Restore your backed up EFS folder.
jje
But i think i backed up the EFS folder with the modified IMEI. What can i do now?
nothing. replace the motherboard
SOLVED!
Ok so tnx to JJEgan i checked all the IMEI numbers and only 2 of them were modified. Thing is before I pached the v5 Ariza, I did a EFS backup with that program. That backup img saved my phone.
Firstly I got my phone back from service with 4.2.1 official ROM (thats nice, cost me 0 $ ). I rooted with CF-Auto and used Ariza patch (v4). But my imei was still wrong so after that I used EFS_Backup_Restore_new_ADB.rar to restore my IMEI/SN with the old EFS backup then I used another programEFS Professional v2.0. I checked the option to repair No network and clicked Restore. After that I restarted my phone and I got the messages from provider with APN settings and so on.
Thank you for the help :good:
worked till first restart... now No network again, I`m not a samsung/android fan anymore..

Have u tried restoring With Samsung Smart Switch
No i have not tried
Try restore it with Samsung switch, if not you'll have to find a way to change the imie no. Back to its original otherwise your network won't register the phone to you.
I got the same problem... I guess the IMEI has been altered or the update failed... i tried to downgrade to 5.1.1 but impossible. :/

I'm also having trouble. I bought my phone out of an independent shop, on purchase they told me it's not possible to update, and basically got the phone at a bargain. But, I have been doing digging. My guess is they have bought a blacklisted phone and flashed a cert to fix it. So my question is.. what is a cert? Does it contain the imei info, and is it tied to the software version the cert file? And will it ever be possible to flash a MM rom. I have tried and it won't go past the Samsung logo, only 5.1.1 Roms work :/
