my friends dad isn't using his t-mobile phone anymore and his contract doesn't expire until January so my friend says i can have the phone but she said i need to buy a sim card for it first and then she will give me her dads phone for free. i dont get it, shouldnt her dads phone already have a sim card in it? why do i have to buy one?
and how much does a sim card cost?
