"No service" after unlock

[Chaka1988]

Hey guys/ladies

I have an iphone 3g 8gb on 4.2.1 with ipad baseband. I jailbroke it with redsnow0.9.6rc8. I then used Ultrasn0w to unlock it. However, when i insert the simcard, it says "NO SERVICE".
What could be the problem?

thanks in advance and HAPPY NEW YEAR

Have you tried rebooting the phone?

Yep.

Make sure your sim card is good. If it is still no service, reflash the ipad baseband.
