bought the phone unlocked sim free.
was originally a 'three' branded 9700
anyways, i slot my vodafone sim in, and it keeps going in and out of service, 98% of the time i have SOS.....
what can i do to sort this problem out? im so freaking mad. in the same location i used to have full bars and 3g constantly on my HTC HERO but now with my 9700 i have nothing.
is there any tests i can do to make sure its properly unlocked?
please help
cheers
