Discussion from another board: HowardForums: Your Mobile Phone Community & Resource - tmoblie and uma questions for H@H?
I am a little confused.
1. If I am subscribed to h@h, then UMA (UPPER CAPS) means I'm tied into wifi and can make free unlimited calls to USA numbers without chewing up whenever minutes, right?
2. If I am not subscribed to h@h, then UMA means I'm tied into wifi but cannot make free unlimited calls to USA numbers and therefore eating away at my whenever minutes?
signal doesn't per se tell you - you must first have subscribed to h@h?
