Hi. Did the mobile chat team confirm if your sim had been migrated yet for the services? If not you really need check  before anything else  

The handset settings may be enabled but it won’t work without the sim updates. Some users are experiencing a small wait in getting their sim updated  

BT only officially support handsets purchased from them, but if your sim has been enabled and it’s still not working, try changing the APN setting to EE and see if that works  if not if maybe a case of the firmware variant not being the correct version for BT to work and may need to be flashed

Re: Wifi and 4G calling setup

Im having exactly the same issue, so do I need a brand new SIM to make this wifi calling work? I'm using a supported handset based on BT's own list and have wifi calling switched no but no bueno so far.

Hi @Gavlar_oosh

As your handset didn’t come from BT the firmware version on the handset won’t be compatable. 

It seems the only handsets with an EVR variant work regardless of them being sim free or unlocked.  You can flash the handset to an EVR firmware but do so st your own risk 

BT will only officially support the S9 if it was purchased from them I’m afraid.

Re: Wifi and 4G calling setup

Do neither work? Or is it just 4G calling that's not working? 

 

If you're definitely on EVR and your SIM has been enabled, there's no reason it shouldn't work. 

 

Did you flash your phone to EVR? If so, did you factory reset afterwards?
