I have an At&t Blackberry Bold 9700. I want to take it from the USA and use it in Buenos Aires, Argentina. I sent away for a T-Mobile SIM card and the unlock code and was able to unlock the phone. I have read that since I had to unlock the phone myself, when I get to Buenos Aires and get a SIM from Movistar that I will have to change the APN information. I know how to get to the APN information on the Blackberry. Does anyone know what I will have to change the APN information to or how I can get that information once I get to Buenos Aires? Does changing the APN number affect calls, texts, data or all of them?
