Calls Cutting Out/In

Same problem as the others in this thread,  However, I have found that if I have the phone charger plugged in during call, calls are substantially better.  Sending this phone to a subscriber is an insult to the subscriber and indicates the disdain Assurance Wireless has to it's customers.  I am presently in the process of transferring to Safe Link. I have a number of Trakfones of eminently greater quality.  Assurance Wireless, this is you Notice of Intent.
