I am moving an Sony Xperia E5 (2017) onto BT mobile from another network.
Sony tell me that it may need a BT firmware update to enable WiFi calling.
Does anyone know if that is a) necessary ; b) possible?
you will need to change your network settings to BT and then see if wifi calling activates and works for you
my question is really about what can be done, if anything, if WiFi calling doesnt present as an option if and when I plug in the new SIM.
Sony tell me that the phone itself is capeable of WiFi calling if the specialised network-specific phone firmware is fitted. They suggested that I contact my network of choice to see if any relevent firmware is necessary and if so can be retrofitted.
WiFi Calling is important to me as the BT/EE network signal is too weak for use in my house, whereas Vodaphone is fine. I would prefer to go with BT as I have BT Broadband and Halo so would like to maximise on the economy of scale.
Any advice gratefully received!
It's usually just a case of insert the sim, get connected to the network and then see if you can enable it via the handset menu.
I don't think there's a way to specifically download a BT firmware update onto the phone, so hopefully it will work for you straight away.
From the net:
you can switch Wi-Fi Calling off by switching the toggle to off.
This thread seems to confirm it is a "goer"
Because of the age of the phone (launched with Android 6) Wi-Fi calling was not baked in to Android at that point and was only present as a network specific addition to the OS.
