iMessage Activation Unsuccessful

[clolord]

Hi. Since a transfer of ownership has happened where my old number has transferred to my new sim only account, I am unable to use iMessage and FaceTime without it saying there was an activation error. 

I have switched both off and restarted the device then switched back on but I get activation failure messages when I select my phone number. I have also reset network settings, changed the number on the phone section and I have taken the sim out, signed out of my Apple ID etc but nothing seems to have changed, and I am starting to get really annoyed.

I just wondered if anyone could help me, it seems to be as a result of the sim as iMessage worked fine prior to my old number being transferred. 

Many thanks

Hi - I’m having the same issue since porting from EE - have been without iMessage and FaceTime for 5 days now. Please can someone take a look? Thank you!

I've got the same issue tried all the steps Apple suggest and it doesn't work so clearly an issue with O2.

I ported into O2 yesterday and it just refuses to activate iMessage on the pay monthly esim in the phone. No other SIM I try (family SIMs on other networks) have this issue and bizarrely I have an old O2 PAYG SIM that works fine for activating iMessage on the same device so it is either a SIM issue or a problem with O2 porting the number in. If it isn't resolved this week I will have to cancel in the 14 days as I am not going without iMessage.
