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...

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.

Not a right place to get technical helps , in regards of your ACE 3 issues ( Galaxy Ace S5830i Q&A, Help & Troubleshooting)
Please make it @ proper section
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..
Hello everybody,
I bought recently my thl W8S, and I was experiencing some troubles with the battery charging (taking 10 hours) and my GPS connection.
So I decided to flash it via CWM. But I'm very new in the flashing and all this stuff. I tried a lot of things to get CWM , even thing I didn't know.
The problem of my IMEI came out atfer I installed this :
http://forum.xda-developers.com/showpost.php?p=19319421&postcount=23
The recovery installer apk, I just click on it and when my phone rebooted, I didn't have any access to my SIM management, no more coverage of course.
I tried the *#06# and my 2 IMEI are just marked as "INVALID".
Since yesterday I tried few different operations to get if fixed but nothing is working.
I tried to use the engenering mode (menu CDS, Network information) and send the AT command with the IMEI but I got an error message : AT command is failed to send.
Then I tried to recreate the MP0B_001 file with some tools I downloaded. And I put it in the right folder (/data/nvram/md/NVRAM/NVD_IMEI/MP0B_001) instead of the old file. I reboot my phone, still the same trouble.
I'm kind of desesperate right now.
Any thoughts / ideas?
I can't find the stock rom to try to flash it with Odin ..
Thank you
Hello
I tried to do this but I can't send any AT command , error message is : AT command is failed to send
Any other idea please?
Hi, Did you finally managed to fix the imei issue? I have the exact same problem.
I have the exact same problem. Who successfully solve this problem?
If you didn't back up your efs partition then the only other allowed way is to send it back to the oem.

Hi to all on xda!
I have recently bought GT-I9300 from friend. When he wanted to sell to me he updated to 4.1.2 stock rom but after update he got error no sim. Now i'm trying to fix it for me. I don't know what version was before but now is XXEMG4. I've checked everything on phone and everything is fine (imei, s/n, wifi, gps..). I done update via odin once again and that pass well but the problem stays. I think maybe sim card get locked. I read over forum that i can unlock sim via *#197328640# but when i select [6] NETWORK LOCK i get error (menu not exist..). I read that i need 4.1.1 stock for this command and if this is xxemg4 update efs is v2 so i can't go back to 4.1.1, right? Can anyone help me? Please...
*UPDATE*
When i go to recovery mode on screen is this:
# MANUAL MODE #
-- Appling Multi-CSC...
Applied the CSC-code : ALB
Successfully applied multi-csc
but my csc is MSR, that rom i installed. Can this be reason for no sim issue?
Network lock is not responsible for no sim message, that's usually due to a faulty sim card or card reader.
Try your sim in another phone and another sim in your phone.
You can't go back to pre EMG rom, the csc is unimportant, there is currently no way to network unlock your phone without a valid unlock code.
All the above is already posted many times, please search instead of creating new threads.
i have searched for this problem but i found only similar topics not same as mine. I have signal so i dont think it is modem faulty also my sim card works on another s3...

In that case if you have read the faqs then you need a service centre repair .
Or simply pay for the network unlock as you have been instructed to .

How on earth does that answers the question posted .
I have tried couple of patched modems but cant solve problem. When i flash patched MG4 modem then i dont have imei and s/n is wrong and instead showing some signal as did it before now is crossed circle icon. I tried that to restore efs backup but imei still was null/null. Then i flashed rom again and imei returns also s/n and no sim card error.
When i try to call then i get message "Not registered on network"...
Take it to a service centre, you won't fix it yourself.

Give a thank if i helped you.
They also want to repair for 200 euro!!!??? Replacing motherboard and sim card reader. Why they want to replace it if it is software error?
User flashing error, not covered by warranty.

The reason is that it has failed warranty status .
Due to wrong firmware but more often phone is rooted or had custom rom and signs have not been removed .
Samsung's warranty is not the sellers warranty and they have a much stricter policy .

I will let you know when i try. I hope too because it also error me no sim card....
No, same error. I will try 4.3 version now...
i found this service manual: http://mobilcoms.ru/load/1-1-0-4505
Has anyone know how i can check voltage on R324 (pdf 08-... page 12)? It is under sim/sd card module. Do i need just battery or i need sim and to turn on phone? Has anyone tried this?
I officially announce that my i9300 is fixed. Problem was in sim card slot (some pins were bent). I take apart my phone i start inspecting it. Checked everything from service manual and it was fine but after i remove sticker on sim card slot i saw that one pin is bent (Vcc) so i use small needle and gently rise that contact up. One side of contact is soldered so you must bent up behind solder. i reassemble phone and power on i waiting for result...No service, ok this is normal, as every time so next is no sim error but then signal bar started showing some reception and SMS from carrier started comming. Problem was in sim card slot....200E saved . Thread can be closed!
Hey everyone!
I have a Samsung Galaxy S6 Edge G925F that will not connect to a cellular network and wont display my IMEI serial number or SIM Status.
I have tried everything:
Flashing Stock ROM with ODIN (Just get a fail)
Flashing multiple modems and AP's
Backing up and restoring my efs
The phone still boots and I have backups of my supposedly corrupted EFS
This happened after flashing a 5.1.1 rom in ODIN
My stock rom is: G925FXXS4DPIB
Nothing works. Please I need help and I dont have access to a Octopus box to re write my efs either, is there a way I can fix it.
When I put my phone into diagnostic phone with qualcomm's tools I just get a "Device has malfunctioned" error, I'm using Windows 10 64bit

The imei app your talking about only masks the imei number and doesn't permanently change it back to what it was. Thanks for trying to helping though
