Default No Networks found

I just recently rooted my phone, and abit confused getting the cellular network to work. When I type in *#06# in the dialer my IMEI does show up as the sticker says behind the battery. I have also flashed all 4 radios provided here (http://forum.xda-developers.com/show....php?t=1982571)
Not sure what the next step would be. (Been searching the forums all day)

I would like to take the phone with me overseas and ny help would be much appreciated
Thanks in advance
