Have you tried going into settings - mobile networks - network operators - select automatically

Find your networks apn settings, save them in setting-mobile networks and reboot phone. And/or flash a new radio, theres several threads with archives/advice about which to use.

Wrong forum location buddie..Address it in here next time http://forum.xda-developers.com/forumdisplay.php?f=1148

probably you'll need the simunlock app if you don't have network
and check your IMEI
and provide more info how did it happen'? while flashing a new rom?

Here's a thought, what have you tried so far?

Sounds carrier side (& in the absence of any great amount of detail from you). Either coverage where you're using the phone isn't up to scratch...Or...Phone is IMEI blocked or some kind of block on the phone by the carrier. In the first instance, call them & ask if there's any issue from their end.
Edit - Speaking of the IMEI, check the IMEI in settings/about phone/status Vs the box/documentation that came with the phone. If you don't have it, if the IMEI in phone settings begins with 0049...., that's your problem. Whatever you do, do not post your actual IMEI here if it's OK, just confirm whether it begins with 0049...or not.

Hello there. I'm having this problem. No matter what ROM I flash, I get either mobile network not available or not registered on network. And I check what you said. The IMEI is different from as written on the phone and when I check it in about phone. And it starts with 0049. Can you tell me what's the actual problem here? and do you know how to fix it? Plz reply asap. Even flashing back the stock rom gives me the same problem.
