另外，我也找不到$50可以買到700分鐘的T-mobile prepaid deal

This is the best deal I can find online: 7% off.

Anyways, I got a T-Mobile prepaid for my father because he doesn't use much. But I still can figure out how to get free internet access. I am planning to upgrade his phone to one that has wifi, so that we can make free calls by using Skyape.
