The overseas customer service is terrible, and they don't know to $#*! anything—lots of idiots working in Asia. Between 0-10 scale, I give -100. If you don't want to run crazy, don't set up a T-Mobile account. Regarding service, bad. I don't have benefits in my area. I contact cust. Svc. Mail me a signal booster. Still no service. I returned the device to the store but forgot to refund the deposit. When you call, these overseas Asian idiots answer the phone and don't know anything. I was on the line for about 27 minutes talking to the rep, and she asked me why I was calling today. I told her, I have some time and I am so lonely you dump idiots. Stay away from T-Mobile. Anyway, over two weeks T-Mobile unbales to fix the technical issue.
