Hi there,
Since Monday 25/04 I have had an on-off message popping around 6 to 8 times a day saying "Could not activate mobile data network. PDP authentication failure".
It happens very randomly, like in waves. I have tried all support I have found online:
- turn the phone off/on
- reset network settings
- take SIM out and place it back in
- airplane mode on-off
- change network selection from automatic to manual selection and select EE.
Nothing seems to work and after a few hours (or minutes), I get the annoying message again.
Details of interest:
- my device is an iPhone 13 Pro Max - unlocked and bought at Apple. Bought it over a month ago and never had issues before.
- I am on a monthly contract with an unlimited data plan with less than 40GB usage per month.
- the phone has the latest IOS, and there have not been reports of mobile data connectivity issues after the latest update anyways.
- my partner has also an iPhone with an EE SIM card (also a monthly contract) and he's not having this issue.
- My iPhone doesn't seem to have 3G option, only 4G and 5G. I never have 5G on because it's not that good tbh and it slows down.
- the four connection bars are either full or at 3 which is the usual.
- I have never had a VPN installed and VPN is not active on the phone.
- No issues have been reported in the area where I am (east London), but last Thursday (21/04) EE had maintenance works in the area. The typical text message they send you with the update.
I tried contacting EE CS, but after literally hours first waiting on the chat, then trying to explain the issue I was cut off instead of moved to the tech team (as confirmed) so ....
Hopefully someone can help before I gain the strength to contact CS again.
Thank you!
