I’m running e on a Poco F1 with dual SIMs (one work, one personal) on the Three UK network.
Three supports wifi calling/vowifi, as does the PocoF1.
Vowifi seems to work on SIM slot1 but not SIM slot 2, even when enabled under ‘wifi calling’.
Swapping the SIMs, vowifi is always possible from slot 1, but not 2.
If I only put a SIM in slot 2, no wifi calling.
Does anyone have any more info on this? Is it by design? Or, as the software implies (vowifi switch for both sims), should it work on both?
