When cellular service is available, your iPhone uses it for emergency calls. If you turned on Wi-Fi Calling and cellular service isn't available, emergency calls might use Wi-Fi calling. Your device's location may be used to aid response efforts when you place an emergency call, regardless of whether you enable Location Services.

Now i've come offshore again and same issue again. WIFI calling not working. Vodafone say it is turned on, it works at home and in the hotel i stay at, but not here offshore.
Hello, I have the S21 Ultra on Vodafone (UK). I am using it with an eSIM and cannot get wifi calling to work. If I use a different vodafone sim in the device it works. however as soon as the physical sim is removed from the device the wifi calling option disappears.
Wi-Fi calling is especially useful when you're in an area with weak carrier coverage. For example, when you're traveling to the residential countryside, or you're in a building with spotty reception. You may already be familiar with using Wi-Fi to send messages when SMS texting is unavailable (iPhone users will be familiar with their native blue-colored texts from iMessage, and apps like Kik and Messenger also provide these services) -- and the same applies when you're trying to place a call. With Wi-Fi, you can call a friend up even if you're in a dingy, underground bar (assuming you can connect to the bar's Wi-Fi, that is).
As for Sprint, it offers Wi-Fi calling on several Android phones too, in addition to iPhones including the 5C and newer. But while Android and iOS after 2016 have no restrictions, phones that launched before that year may not be able to make outbound calls outside Sprint's coverage areas (incoming calls may still be available, however).

I had huge problems trying to get vodafone to give me wifi calling. Had been using a suresignal box for a while and eventually got them to set it up properly a month or so back after claiming it was for over a year.
It should just automatically turn off the mobile aerial when it has wifi! And some operators do indeed seem to do just that; not just EE in the UK but my pals in the USA get 2-3x their battery life on wifi calling.
Another great thing that works over EE (not sure about the others) is even when on Wi-Fi calling with no signal at all on the mobile network, it is still possible to use the options on the phone to set call forwarding or voice mail options, so essentially all functions of the mobile network are available over Wi-Fi.

I'm sorry, but this is a must (sucks for me because I have to walk about 100 feet from my home to get a T-Mobile signal). You can check your current connection on the Moto X4 with dialer code *#*#344636#*#* (sorry, I did not confirm this is the same on other approved Fi handsets...not sure if this is via SIM). You can temporarily force a connection to T-Mobile via dialer code *#*#34866#*#* on the Moto X4 (and I did ask if this is the same on all current Fi phones, yes was the answer, but not confirmed). Yes, if you reboot, no more wifi calling until after a TMO connection is established at least once. Please update below if you find otherwise on the dialer codes.
My wife is with Vodafone and her phone (Samsung Galaxy A40) also has wifi calling enabled on it. The Vodafone signal is also poor here. The same thing sometimes happens to calls received or made on her phone at home.
I put the S9 into flight mode and turned wifi on. I then attempted to make a call. There was no ringing sound in the earpiece so I assumed that the call had failed. The person I had called then rang me and asked me if I needed to speak to him as his phone had rung, showing me calling!
I also recall that, a few days ago, my wife called me from here using her A40 - also with wifi calling enabled and a poor Vodafone mobile signal. During the call, the same thing happened - she could no longer hear me but I could hear all that she was saying. From this, it would seem that the problem is not phone-specific. 2ff7e9595c
