Does anyone know of an equivalent Wi-Fi handover service that will work with a Pay As You Go SIMM? Preferably without requiring an expensive phone.”
I was in the same situation, not quite zero-coverage village but the same end result. And indeed, UMA gave the same end-user experience as WiFi calling but using a "legacy" technology. For the same experience, as others have pointed out, you'll need to start using WiFi calling "proper" i.e. on a 4G-enabled device.
You may also be able get an EE Signal Box which I've had installed in one of my problem locations and works a treat, with the only caveat being handovers to the mobile network not being as seamless as with UMA.
