Neil traded up his iPhone 8 Plus to the iPhone X, and he wants to know if Wi-Fi calling is a good idea. Should he turn it on? Leo says that the cell carriers would like him to use it if they support it. It doesn't use their towers, eliminating congestion, and they can still charge him for usage. Would it be of any benefit to Neil? Leo says not really. Quality will vary and if he has a poor connection, that could be an issue.
