Hello, I activated a metro pcs phone in California and then moved to New York city six months later. For some reason my phone works in New York City and Florida but NOT in Philadelphia. Can anyone give me any advice on how to unlock the phone so that it works in Philly? Metro PCS has a HUGE network in New York and Philadelphia so my phone should work there. Apparently I had to dial some sort of code BEFORE I left California in order for it to work out here and of course they don't tell you that. Can anyone help? Thanks!
