I (and Customer Services) have a problem getting these services up and running on my new O2 Sim only contract (with ported in number from Vodafone). I've enabled the service in MyO2. All other services, including 4G (VoLTE Off) and Wifi work normally.
On my iPhone 11 Pro Max, when I attempt to select the "4G, VoLTE On" option I get the following error back "Cannot Activate 4G Calls, To enable 4G calls on this account, contact O2." When I attempt to enable Wif-Fi calling I get this message "Wi-Fi Calling, To allow Wi-Fi calling on this account, contact O2."
I have tried the usual rebooting of the phone, resetting network settings and checking the apn details are correct. I have also tried the sim in a Samsung Galaxy S8+, but the option to enable 4G calling is greyed out. I've also been on different cell sites and different Wi-fi networks.
An O2 Guru tried removing the service from my account and then adding it again, but again this didn't make the service available on either device. This has now exhausted the help O2 Customer Services can offer so I'm wondering if the wider community has any helpful ideas before I go grovelling back to Vodafone...
Solved! Go to Solution.
Having done my morning reboot of my phone, I can confirm that both elements are now correctly working! Whether time, the great healer, or Cust Services fixed it, I can't be sure.
I hope other customers experiencing this problem after a port-in have had their service fixed and get reassurance that they don't have a problem with their iPhones and that it can be resolved successfully.
However, @O2John , please send my apologies to your gut as it failed you on this one 😛
What device does it say you are using in your MtO2 http://www.o2.co.uk/myo2 ?

Sounds like the problem then in that no device has registered on the system yet @GMF
Sadly the SIM swap didn't work.
Do any of the O2 staff lurking here have any insight as to what's going wrong with 4G and Wifi calling at the moment? Surely they don't want to drive another customer away? Looks like @joenitro has already cut and run 😞
(sorry if i missed anyone)
There's a couple of things that spring to mind with this one.
We did have issues lingering around numbers porting in last month, but I'm not aware of anything in particular. The other common issue is on handsets not supplied directly by O2, there's sometimes a firmware issue that prevents WiFi calling from working - although I've yet to encounter this on an iPhone, it's always been Android devices I've seen this on in the past.
