Can't receive certain texts (2FA etc) when using Wi-Fi Calling

[CorrectHorseBat]

I have an iPhone 12 Pro on O2 and using Wi-Fi Calling.

I can receive most texts but 2FA codes, e.g. from eBay don't come through when using Wi-Fi Calling, I have to wait to get mobile reception back. As far as I understand it Wi-Fi Calling on O2 should now support SMS.

Please can somebody from O2 help? O2Sarah-?

Many thanks.

Evening, 

Is this still the case? I have an iPhone 15 Pro Max having the same issues.

Thanks.

@CorrectHorseBat I see you directed your question at O2 Sarah. All agents were removed from here last July so only Customers here now.
