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.

I wasn´t placing any trust in Grok, I was just using it to support what for me is a fact (but what for you is only my claim) that I´ve been benefitting from Wifi Calling on my O2 PAYG SIM for the last six years. I´m in no position to hazard any guesses why this is the case, but I´m not complaining. Now my Nokia 8110 4G is showing its age and I feel it´s time to yield to the pressure to enter the modern era, so I´m on a quest to find the best way of getting Wifi Calling on a smartphone without taking on the worst consequences of having an applications layer. Thanks for the heads-up on Giffgaff -- I´ll investigate further.

Thanks for the feedback png. I hope I don´t come over as being abrasive (always a worry for me in this mode of communication) but I was a little confused by your reply... seeing the initial IF clause I was waiting for a subsequent THEN clause but didn´t find one. I infer, then, that you were just informing me that different providers operate differently in respect of Wifi Calling even when they use the same network. The Giffgaff thing looks worthy of further investigation.

Thanks Enlli, I´m beginning to understand what a complicated situation this is.

Thanks for the tag @pgn 

As our pages confirm WiFi and 4G Calling isn’t available on Pay As You Go at the moment.

@Andy_Kay1 It remains a mystery how you were able to access this service 🤔
