Problems with Sony Ericsson Z525a Cellular Phone

I got this phone from AT&T

got it unlocked

and took it to DR as a gift. However, they are not able to use the phone with the local service providers, the phone seems to recognize the sim card but loses signal right away... Do i have to change some setting like frequency or ports in the phone? maybe a factory reset? if so, how do i do that?

any suggestion would be appreciated.

Thank you!

First open your phone and be sure it is on. Next select Menu. Press the joystick right 1 time then down 2 times to get to "Settings". Press Select. Joystick up 1 time to get "Master Reset" & select. Joystick down 1 time to get "Reset Device" press select. Press "Yes" and the phone will be reset and restarted. Hope this helps. -Mike
