Hi Kath, thanks for sending the link to the page. 4G calling will work great if you have a 4G signal.
The problem is when you do not have any signal hence need wifi calling to make/receive calls. It is so frustrating that other network providers wifi calling works perfectly. I am sure you can appreciate having 3 out of 4 incoming calls fail to connect is unacceptable.
If you have any other advice that would be appreciated.
Thank you.
