iMessage and FaceTime not working

[Dave24]

Hello,
I have just ported my number over from Virgin to O2 and ever since that took place I cannot activate Facetime or iMessage on my iphone13.
I have carried out the following:
1) Switched off and on

2) reset all network settings

3) Restored phone completely

My Number is showing the correct number.

I have tried contacting o2 "customer service" but it is an absolute joke that starts off with an automated service that takes about 5 mins to get where you need to go and then gets out.
The chat is always busy.
As I am new to O2 I am in the calling off period, so I think I might just cancel my contract.

Try resetting your network connections.

I have the same issue. Ported the number from Three a month ago and I hadn’t managed to activate the iMessage since. It’s O2 issue, as no normal steps of resetting the iPhone would work.

If resetting the network settings doesn't work, you'll need to get a new blank sim from O2 and do a sim swap to activate it Guide: Sim Swap: a mini guide 2017 update 

This will resolve the conflict with the number embedded into the O2 sim card.

Ok, will try that, as after resetting the network, I’ve also lost the visual voicemail

When you speak to O2, ask them to enable iData on your account too.
