I have an issue with two of the above - wifi calling periodically turns itself off (the icon disappears from the status bar). Both phones are bang up to date. Vodafone SIM is in slot 1 and both have an EE SIM in slot 2. wifi calling on the EE SIM cards is fine. The problem persists across wifi networks so I'm confident it's not the devices or the wifi networks they are connected to.
Previous to the current setup (Voda in slot 1 and EE in slot 2), one device had two EE SIMs (one physical and one e-SIM) - no issues with wifi calling on either SIM. The other device had EE e-SIM as primary and an ASDA mobile SIM in slot 1 - no issues with wifi calling on either.
Any ideas?
