WAP - Esato archive

Posted by yomojo
i have GPRS or WAP on my samsung d510 and i have about 2 questions concerning it.

1.it's an unlocked phone, but the service provider is tmobile. if i use GPRS under my wireless internet connection, does it still cost money?

2.i finally found out how to connect by using my internet information, but what if i want to connect at some other place? do i use the same info. or must i update it?
