Hello can some one please help me with my phone...........
i travelled over to Thailand and got myself 3 cellphones, all 3 are quad band ( as so it said on the box) Now when i came back one phone works and the other 2 fail to register to a network;
when i go in to network settings and press search for networks it starts to search and then it just gives me this error message "request failed" or failed to connect
Can some one please tell me on how i can manually connect to a network? or to do something.,,,,
is there maybe an actual way to find out how many band the phone is or the frequency of the phone

Ill be very thankfull if someone can help me
