Saulcr you may have to do a manual network selection. Go to phone settings, network settings, prefered network, and keep searching and trying each network in the area until it works. Be forewarned that roaming charges may apply.

Pda p168


i think the phone is network locked and thus not detecting any other networks

try and check with the network that you have found signal if its on network lock with them

try and get it unlocked either outside or in the network shop and you will be able to use any sim after that
