so basically i got given a
8520 for free off a mate, and when he had it, it worked fine. the mobile was locked to T mobile and i have an o2 sim.
i used some website to get a code to unlock my phone and now my phone reads my o2 sim
but the thing is i cant send,revives texts nor can i call anyone and i don't get calls
seriously what is up with my phone? i have plugged it into my computer and factory restored it, but that didnt help
i always have "gprs" next to my single strength and some times " edge " what do these mean? :S
its not my sim card that is broken because it works in other phones
is there something seriously wrong with my phone or is it a simple fix?
Thanks for the help <3
EDIT: when i go into advance options and go onto sim card and type in MEPD it shows everything disabled which means my sim should work fine with it?
