This is the common problem in some Galaxy S3, and there are 2 options to solve this:

  1. Turn off your phone, Remove SIM card, turn on your phone and again turn off, insert SIM card and now turn on your handset.
  2. Change the Mobile network mode to GSM/WCDMA (Auto) - Go to settings > more settings > mobile networks > network mode and make changes. I mean make it to automatic. (You may also try changing to other option and after few seconds change back to automatic mode.

I have the same issue. But I've done that countless times, also flashed new roms clean install and all. Still don't have network. Only WiFi works. Any help please?
In your Phone: Go to settings<more settings<mobile networks- then touch the option network operators to scan the available networks in your area, wait for some moment, let your phone scan, a list of available networks in your area will appear then, select the network name of your service provider to register it and you are done. You can restart fore more efficient use then.
