Help please, 7230 network issue
hey guys, i'm new to the world of blackberry and i just got an unlocked one of eBay recently. My issue is that with my old phone, if i couldn't connect with my home network (tmobile) then I could connect with Unicel and AT&T if their service was better, but I can't do this with my new BB. I'm sure it is unlocked cause my girlfriend (unicel) put her SIM in and she could get Unicel. Pretty much m question is why can't I roam on other networks like I could with my old phone?
