My data disappeared while I was asleep from 6% used to 6 % left. No answer except that's me using data. Be careful if they tell you you can save money by switching to an unlimited plan....they lied costs 11.00 more per month. And all they said was the system made an error when person ran numbers...this morning I haven't used any data and had turned on all apps etc....seems a new way to get more money. Don't trust the help you may get to be honest!
