Can't get wifi calling working

[StephenW]

Have a new O2 sim for my iPhone 11 and have activated 4G & wifi calling on the website but just get the 'to allow wi-fi calling on this account, contact O2' message.

Have reset my network settings several times, have waited over 24 hours, have had a call with customer services (the call handler seemed to have no idea how to resolve the problem), have checked that I'm running the latest iOS version ... but still it won't activate.

Does anyone have any ideas on how to resolve this?

@StephenW 

@O2Lisa will message you in the morning.

Also just noticed that visual voicemail isn't working either!

That's also because you don't have iData enabled @StephenW

Morning all, thanks for the tag @MI5 

I'll message you privately @StephenW and we'll get this sorted for you

Hi MI5.

Just wanted to give you an update after all the help you provided yesterday and, of course, to thank you for that.

Lisa at O2 has been on the case throughout the day today but has not been able to fix the problem - so neither 4G nor wifi calling are working.  Apparently iData was activated on the account.  The tarriff was fine, as was the handset (iPhone 11 running 14.6). Very annoyingly, it remains a mystery.

So I have cancelled the contract as the next step would have been a referral to the engineering team which would have taken up to 5 working days!

Oh, and the customer services guy that I spent an hour on the phone to yesterday and promised to call me today when he's had a chance to get further advice from his team ... guess what ... no call!

All in all, a really frustrating experience and a massive waste of time.

But thanks again for your very positive part in this.

Best wishes.

Sorry to hear that mate and good luck with your next network.

It's a shame we have to suffer from such poor systems with O2.
