pdp authentication failure

Here is a suggestion from another site -

1. Remove the SIM card from your iPad, then turn off your iPad, wait are few seconds, turn your iPad back on, then reinsert the sim card and wait a few seconds. See if this fixes the problem. If not:

2. Go to Settings -> General -> Reset -> Reset Network Settings on your iPad to reset the network setting on the iPad.

I am having the same problem and have tried all your suggestions - any idea on next steps? Thank you.

Two things. Try deleting your settings and then enter them again. Failing that ask for a replacement sim card!

Thank you.

I tried all solutions but the only one worked with me is :

Changed the SIM then return the original one back again & it worked fine with me.

Another solution. This worked for Vodafone in Australia.

1. go to settings/cellular data/apn settings

2. in the apn box, change to "vfinternet.au"

3. turn off ipad then turn back on

One more way is connect device to PC, and open itunes, > it will ask for upgrading network settings> download and upgrade.

wait for 5 mins,

On device you can see it searches for Network.

It will automatically connect to a Network.

> Now you will be able to browse.

This worked a treat

This was the only thing that worked for me on my iPad mini (Also on Vodaphone) Thanks for that 🙂

Thanks AussieRSW I followed your suggestion worked great thanks Oosht; Adelaide South Australia

In my situation that I faced in Finland with GSM operator dna, you have to make a phone call to activate sim card. If you directly put the sim card to the ipad it gives you this error. Hope this helps ;)

AuSisRWS ,thank you so much

It worked out for my iphone 5s !
