I have a 7th gen iPad that when trying to use data over T mobile network it says PDP authentication error and will not connect. It still works on WiFi. T mobile was no help but they did switch out the SIM card and Sid they checked network settings and everything is good. Anybody have any ideas? I would appreciate the help.
