I m facing the same problem and I tried everything , I m from India and using carrier is Airtel, I talked to the customer care about it and they said no problem from there side,so I guess something wrong with my mobile, can anyone plz help me out here,, thanx

Try the Hard Reset (press the Home and Power button together for a few seconds) and it must work. If not and if u have a backup try to do restore. I had this problem several times, sometime the hard reset works sometimes not so i do restore.

Hope this helps u

I've got this iPhone 5 for Christmas last year. Works normally. I went to Singapore, turned on 3G with data roaming and finished up my phone credit. Came back home, [3G subscribed for my home country a few days before I went to Singapore] turned it on, got the PDP authentication failure. I've tried:

- Multiple hard resets
- Settings > General > Reset > Reset Network Settings
- unlockit.co.nz

- Removing sim card and hard reset
- Normal turning phone off and on

- Letting my phone run out of battery and charging it

- Switching airplane mode on and off

I don't want to let the 3G subscription go to waste because I haven't used it this month.

On a lighter note, do you think it's time for a new phone? ;D

Hi i also faced the same issue yesterday i.e. 18th Oct 2013 in India and service provider is AirTel as soon as i switched from 3G 1GB plan to 3G unlimited plan.

I've tried:

- Multiple hard resets
- Settings > General > Reset > Reset Network Settings
- unlockit.co.nz

- Removing sim card and hard reset
- Normal turning phone off and on

- Letting my phone run out of battery and charging it

- Switching airplane mode on and off

My Service Provider was helpless in solving this issue. I told them that i started to get this error message once switched plan but they couldnot do anything and told me that there is problem with your iPhone . So i asked my service provider that i again want to switch back to 3G 1GB plan from 3G unlimited plan. And luckily net started to work like previous once i switched back to 3G 1GB plan from 3G unlimited plan.

So I don't think this is iPhone Bug but yes there might be some techincal factor causing this problem.

I just got this problem fixed for Argentina calling t-mobile tech support. They were great.

Calling worked.

SMS worked.

Data - did not work. APN Authentication Failure

Tried before this

- airplane mode

- cell settings reset

- power cycle (turn off/on) phone

- hard reset

- network setting reset

- several APN profiles (only useful if you change to local SIM card)

The data roaming ON was set on my phone, but that wasn't working on movistar service. They had me dial a special code to turn that on on the network for my line.

#766#

And it turned data roaming on and instantly - data was back on.

The issue occurred for the second time on my iPhone 4S (7.0.4) today. I bought the device approximately a month ago. 'PDP Authentication failure' error happened to me after a week or two of using the phone when I was still using 7.0.3 iOS version. Update did not help as some users suggested it was old iOS issue. And aprooximately two weeks later I encounter the same issue. (Which was previously resolved by - as a last resort obviously - hard resetting the device).

SOLUTION: So far only hard reset helps!

Bug description:

When the user tries to connect to mobile data internet he encounters a 'PDP Authentication failure' prompt and he is no longer able establish mobile data connection 😟. Please note that the issue appeared randomly without meeting some extraordinary circumstances. Mobile internet connection worked perfectly to suddenly stop being functional without making any changes in the device settings/network settings.

Additional information:

Resetting only Network Settings did not help.

In general all the issue solutions provided by the user's here were fruitless 😟 (beside hard reset, obviously).

I do have and always have had the funds to use mobile internet (in case anyone asks).

Here's a short report of a fellow QA Tech for you guys. Make the best of it 😉.

Environment:

iPhone 4S (7.0.4)

iPhone 4S (7.0.3)

Reproducibility rate:

2/80 (number 80 is the result of multiplication of 14 days use of the device by the number of times [4-10] it switched between wi-fi and mobile internet each day)

Expected results:

Please ensure user is always able to connect to mobile internet connection when possible.

Steps to reproduce:

1. Connect to a wi-fi and have the network remembered so it joins it automatically

2. Have active mobile internet connection turned on as well when no wi-fi is available

3. Switch between wi-fi and mobile connections XXXX times in a relatively short period of time (in my case it was approximately 7-10 times during 5-8 hours)

4. Open Safari and a random site

Observed results:

The 'PDP Authentication failure' prompt appears and the user does not have mobile internet access anymore.

Point is, I prefer not to reset my phone the hard way each time the issue appears 😟.

pls fix thx 🙂

Had this problem for the first time today. So I went looking for a quick answer and stumbled across a hint in one of the fora: Make a phone call.

So I just called my landline from my iphone and hung up immediately after the connection was made.

Problem fixed! Data works normally.

I had the same issues using my US T-Mobile iPhome in India . The reason was it was connecting to a network which was not allowing authentication...

It was a easy fix - just select a different carrier and you will be all set .

Steps -

Settings -> carrier -> uncheck automatic selection - > select a carrier

you may have to hit n try which one works.

if you are in India, try Vodafone or airtel

Good Luck!

Agreed! Have a good day.

I have this problem too!! I've try all method but it doesn't work. I use iPhone 4s, my carrier is China Unicom and I use firmwere version 6.0.1 Please help me.

I have this problem too, just started this morning I'm in Italy using fastweb. I tried the hard reset nothing. Don't know what to do.

I had the same problem, and I did the Hard Reset (press the Home and Power button together for a few seconds) and it worked.
