Hi this is starting to really bug me now Im unable to register on a network I get signal bars but only get emergency calls only tried dfferent sim cards and reverted back to latest official stock to no avail any suggestions please
As per multiple identical posts .
First is your IMEI correct
Are your mobile network settings correct
sim card correct and tested
correct modem and csc.

Check your IMEI number. Sometimes, when we flash custom ROM, the phone looses its IMEI number. If it's true, you must use an EFS backup to restore it.
Second solution : your mobile phone was blacklisted (if it was considered as stollen).
Network
Hi thanks for the reply I have been searching I've checked my imei in status and it matches details under battery compartment i'm still paying for the phone (pay weekly) so no reason it would be blacklisted ok just tried another different sim card on Vodafone official s3 stock rom and it registered hmmm im on talktalk which uses voda I know this sim works but i'll get them to send me a new one thanks for your time guys
I am using Samsung Galaxy Chat B5330 (officially upgraded from 4.0.4 to 4.1.2). It used to work fine, but since a few days I am not able to call or send sms or use any network related services. It gives me error : "Not Registered On Network". I tried applying manual network settings. At first it gives a pop up : "Registered on Network". But as soon as I try to make a call, the same error : "Not Registered On Network".
Also I haven't yet rooted my phone.
I thought that factory reset would have been the solution to my problem, but unexpectedly , this too did not work for me. Please help.
Check if your IMEI is intact (by dialling *#06#)
If it's good, make sure it isn't a network problem or server error from your carrier itself

i have tried checking the imei and serial number. They are fine.
Also no problem with network provider because other phones with my simcard are able to use the network.
No problem with my sim card because it works on other phones.
Also my phone is able to use simcard of other phones.

Flashing firmwares shouldn't change a IMEI you need to check and make sure what ever IMEI is on your device passes cert of check and or isn't blacklisted
If imei change to 00000 and can't connect to network, means u lost it. Hope u had backup EFS.

Hey guys new problem
After flashing the stock Kitkat ROM I realised that the OTA updater doesn't work, so I googled around some more and found the latest (I think) Lollipop ROM (A7-30HC_S127_151125_ROW) and flashed that with the SP flash tool. Everything works fine except for 1 major issue.
The SIM doesn't work and I can't make or receive calls and messages. The SIM is fine, I tested it on another device and I can make and receive calls without any issues. But on the tab it detects the SIM, data works, but calls and messages do not. On the status bar it shows 3G and the little reception bars. When I check the SIM status in settings it shows the network, but the Signal strength is 0, Service state is Out of service but the Cellular network state is Connected.
Is this a problem with the ROM? Do Lollipop ROMs for this tab have any issues like this? Should I downgrade back to Kitkat or try an older Lollipop ROM (like this one A7-30HC_S126_150824_ROW)
Help would be much appreciated
Edit: I just realised that it's saying Invalid IMEI on the lock screen, and when I type *#06# on the dialer it says Invalid
Have I lost the IMEI now?? Is this going to be a permanent problem?
Okay guys I fixed it with the help of a little googling again! XD
Followed the instructions given by the first result when I searched for invalid IMEI
Thankfully the tab had a sticker with the IMEI pasted on the back, so it was easy enough to type the commands with it.
Restarted and now everything is back to normal
