Wifi Calling unavailable on Pixel 6a running GrapheneOS?

[Andy_Kay1]

I have had Wifi Calling using my O2 SIM in my Nokia 8110 4G on PAYG for years (because home network reception is non-existent).

I recently acquired a Google Pixel 6a phone, flashed it with GrapheneOS, and inserted a new EE SIM. Wifi Calling was available so I enabled it and all was well.

I moved my O2 SIM over to the Pixel in order to start using it as my principal phone, but I find that the Wifi Calling option does not appear. I have no home reception on the Pixel and so have had to move my O2 SIM back to the Nokia.

Can this be fixed?

Thanks.
