Help with understanding TMobile cell phone rate plans

Re: Help with understanding TMobile cell phone rate plans

Would I be considered a traitor if I say that I am thinking about getting an iPhone? I just got iPad mini (was cheap and my sister got one before moving back to Pakistan and I needed to get in touch with her through facetime) and wanted to see how to the product integration works within apple. Anyone tried that with the exception of facetime and imessage?
