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...

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.

Hi everyone,
I'm Naveen from India. I installed various ROMs with the respective kernels - CM7, MiniCM9, MiniCM10, JBMini, Shin Engine, etc. but i face 2 problems with all of them. Here are the problems I'm having with the phone now:
1. Not able to connect to the mobile operator network. I use AirTel and I'm not able to connect to it. I have tried with other SIM cards too. I tried searching for networks and out of the list that appears, when I select AirTel, I get the error "Can't connect to this network right now, please try again later"
2. Bluetooth not switching on
Though Wifi works, I assumed that it's a problem with the baseband and I tried flashing baseband from the stock "ftf" file but it's not getting to work.
Please help me if there's any solution to this problem. I love the custom ROMs and I do not want to go back to the default stock. Thanks!
Hi, not new to rooting etc. (have a ZTE Blade which have rooted & custom rom in past).
Have inherited Xperia NEO. Was on 2.3.4 stock & locked to UK O2 network. Now does not recognise SIM card (OVIVO on UK Vodafone network) at any software version 2.3 or 4.x.
Have used flashtool to get to 4.1.B.0.587 - fine.
Rooted with DoomLord - think it worked OK.
Tried unlocking with PlasmaTool - had to short a couple of pins to put into test mode. Tested it recognised the phone but did not go any further. Think this is what screwed it up.
Have since got SIM unlock code from O2.
Have also tried 'RESTORE' in S1tools (found in other threads) & reflash but still not working.
Any help welcomed please - how can I get phone to recognise SIM again ? Thanks
Fixed.
If it helps anyone else - I wasn't using the S1tool correctly.
Clicked on Identify, connected phone as directed, clicked on RESTORE. then have to disconnect & reconnect phone as directed. Then says Restore Complete.
Inserted other network SIM - booted phone and prompted for Unlock Code.
Hi Everyone,
This is my first thread..I need some help with problem.....
My phone continuously restarts when it tries to find a GSM network. Phone has no issues with WIFI/Bluetooth as it perfectly works when the SIM is not inserted. It started when I was using my google maps and enabled GPS on my phone...the phone got heated up and shutdown...since then when ever i insert a SIM it restarts....but also during my experiments i found my phone is stable and accepts the SIM when its connected to a charger !!!!!
Steps Tried:
Reset settings and restore to factory defaults
Tried to repair with SEUS/ PC Companion
Update to ICS
Reinstalled ICS
Unlock boot loader, root and install CM10 nightly coconut
Tried a different SIM also different vendor.
Took phone to Sony service center they are unable to diagnose the issue
Any know any tshoot please help
I have a Sony Ericsson Xperia Mini St15i, officially unlocked bootloader with custom Xperia Ultimate HD 5.0.1 for all MDPI ROM, Android 4.0.4, baseband 86. This is the only ROM where I did not have problems with registering the SIM to network. After two weeks of use I got suddently a "No signal" message, registering to any of the available 3 networks is unsuccessfull both in automatic and manual mode. At network search I always get the message "Can not register to network. SIM card not present or network not available". I tried all the available basebands and different custom and official ROMs, but nothing worked except of the Ultimate HD 5.0.1.
When I take out the SIM and put it to any of my old phones, the SIM registeres without any problem and the network is fully functional. Afterwards I move the SIM to my Xperia Mini, the SIM registers as well and network functions for a certain time only (usually a week or two).
Anybody experienced this behaviour ? Is there any workaround ? Any help please.
