I signed up for T-Mobile 'cauz my hubby had it and they have some kind of T-mobile to T-mobile plan. and dang it if he didn't go a few months later and sign up for cingular. Anyway, T-Mobile is a pretty good company unless you go over your minutes and whew! they start charging you absurd amounts of dinero!! I paid my bill this month, checked my bank acct just to make sure but apparently t-mobile is saying i didn't pay. funny i'm still out over $87. tried calling customer service but they were unavailable. and i get charged for messages even they send me.
