make sure you have inserted the sim card in properly as shown in the sim slot at the back of the phone above the processor

[Guest bamsisgod]

i have done that before and it has done the same thing or if that doesn't work try another SIM from the same network or a different network if it is unlocked. if none of those work turn the phone off. then hold the blue button and turn on the phone.

It will come up with "Master Reset Y/N" click Y if you see no other option and leave the phone for 5-10 minutes to restore itself to factory settings then try

thats alright mate just doin my bit

[Guest bamsisgod]

make sure you renew your mms settings and data connection settings, because the hard reset restores your phone to factory settings other wise you will have trouble with getting online and sending mms messages
