You might be lucky indeed. If they have set up their android phones to use WiFi calling somewhere else AND you in the past have given them your WiFi password to log on their phones the reset would be automatic. That is whenever they walk through the door and their mobile signal deteriorates their phones will automatically switch to WiFi calling through your network. All you will have to do once you get the Vodafone sim is switch on your phone to WiFi calling (a simple toggle) and you are up and away!
