You are probably sick of hearing this problem but I have had it and I have tried to scour the internet and I cannot find a solution to my problem.
Basically I have not used my Samsung Galaxy note 2 GT-N7100 for 6 months or so and I decided to use it and to use a new rom. Now after I installed it I could not call anyone or text anyone nor could anyone else call me or text me. However, the internet was working which was strange but again I got the same error message "not registered on network. I tried to install another rom in the hope that the problem would be sorted out but this time I cannot get the mobile data or the wifi to work either. The main problem is the "not registered to network.
The first rom I installed was the latest Hawkish extreme rom and the second one was Android Revolution HD by Mike1986 if it makes it easier to help me. I will still be searching on the internet but if someone can help me that would be grateful and much appreciated.
Thanks in advance
