I just switched my plan from an old $64 1gb unlimited plan to a new $55 1gb + 2gb unlimited plan. I just received my bill and it has a $20 airtime bill on there. Sounds to me like a mistake. My plan was unlimited why would they charge me $20.
My plan is unlimited. But i notice at the bottom it said 883 minutes. That's not unlimited. I had 844 minutes so for some reason I was charged for 40 minutes. Sounds like a system issue to me. Besides since when does unlimited have limits?
