For the past few days I can't connect to data at all and get pop-up saying "PDP authentication failure" On my iPhone4.
I can still call and do sms.
I have North America plan and in Canada for couple of days. I come here quite often and there was no issue before until few days ago.
Ive done couple of thing trying to fix this including
-Update to latest OS
-Switch roaming carrier
I put my SIM card to other iphone and still getting PDP error so it's not a devise problem.
Called customer support but no solutions what's so ever. My account is in good shape.
One thing that comes to back of my mind is, I receive SMS from T-mobile saying they have implemented some extra fee
for Prepaid customer.... blah blah,,, and since I'm on monthly plan (I was with prepaid plan before) I thought it's weird and eraced the text.
So it could be technical glitch on account problem?
