OK so I've had this phone for over a couple months now and still can't seem find out which service provider I can use to activate this wonderful Sony Xperia Z1 Compact phone of mine....when I first purchased this phone I fell in love with it an can't remember which service provider works for it, Im pretty sure there's only three different options I can choose from either AT&T or T-Mobile or something else and I'm not even a hundred percent sure on that if anyone can help please let me know ASAP
