What you need to know
T-Mobile is retiring Wi-Fi calling for select devices.
The devices affected are still using Wi-Fi Calling 1.0 from 2015.
Starting May 31st, devices using Wi-Fi Calling 1.0 will no longer be able to use the feature.
As technology progresses at the speed of light, that means carriers and phone makers can only do so much to continue supporting older devices. We've seen a renewed commitment by the likes of Samsung and Google to support phones for at least three years, which is a far cry from the days of only seeing one major software update and few security updates.
