PDP authentication failure

Hola y'all

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

-Switch on/off

-Sim in/out

-Update to latest OS

-Restore iPhone

-Hard reboot

-Switch roaming carrier

-Check APN

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?

please help.

  • Thanks for posting @piperoni‌!

    Gotta hand it to you, you've covered a lot of the bases needed to fix this yourself. Sorry calling hasn't fixed this but have you given our T-Force team a try? You can reach them on our Community-2153 page using social media. A trouble ticket may be needed now if this issue still continues and they can help file that for you.

    Good morning, bringing this thread back from the dead.  I too was having this issue initially on my iPhone 13 Pro Max while in DR a month ago… did the standard resettings to no avail.

    Yesterday we made it to Canada, upgraded to the iPhone 16 pro max a week ago and same thing…

    So thank I found this post as I did #766# then #763#, restarted phone and now that seemed to do get things to work!
