After purchasing more data from ATT, I have't been able to get my email or get on safari. I called ATT and they said because I used all of my data, but I don't think that was possible. I have had the $25.00 data plan from Att since I purchased the iPad. I just added the 14.99 plan because near the end of the first term I sometimes do run out. This time I purchased the 14.99 plan on Sept. 16th. My other plan starts on the 21st of each month. According to ATT I had no data left on the 22nd. They gave me a new password to enter at the time of the second plan purchased but see no place in settings to enter it. When I try to get my email or go on safari it says that there is no connection. Do I have to reset something? Was my first plan replaced by the second?
