the ones ive got atm dont give any error messages and when i look in Settings>Usage menu it tells me the some small amounts of data have been sent and recieved but it just doesnt really work, nothing works on it at all...generally tells me it cant connect to server...settings i use atm are:
APN: payandgo.o2.co.uk
USER: payandgo
PASS: password
anyone know any settings that work properly???
