No networking

Hello guys,Sorry for starting a new thread for this question.All the answers in the other threads didnt work for me.I have made a custom rom and I tested it on my device but I found that there is no network even if SIM card is inserted.My rom is based on CM7 and have to get rid of this bug. I can get network coverage when I use other custom roms.Is it because of any tweaks that I used? Or is it something else?


Please help!!!!!!!!!!!!!!!!
