I bought a blackberry 8900 off of someone, i didn't reset it or anything. I just put my simcard inside of it and thats it , my account is prepaid because i don't live in the U.S i live in the Dominican Republic and i'm leaving later on this week. I was wondering if when i go out there when i unlock my code, will the PIN work in that country? or do i have to call tmobile and tell them i'm using the phone out of the country. i've been serching on google and some people say the owner has too call and drop the pin from some server. but i'm not sure if when i go too D.R. since i unlock it it'll work automatically.
any help? please .. .
