T-Mobile plans to have three more devices available by the end of the year.

It’s also worth noting that T-Mo says that it’s “working with others so you can eventually enjoy built-in video calling across wireless networks”.

T-Mobile today announced video calling over LTE and Wi-Fi from the new Samsung Galaxy S6 Edge Plus and Galaxy Note 5, with more smartphone models that will support the feature lined up.

With T-Mobile Video Calling, the idea is to basically offer Android device owners something that feels more native to the user experience, in order to better compete with things like Apple’s FaceTime, for example. If the person a subscriber is calling can’t take video calls, the video call icon is grayed out. If you’ve got either device, you’ll get an update today to enable the feature.

Video calling works over LTE and Wi-Fi, and can move seamlessly between the two as T-Mobile’s HD Video calls do. T-Mobile wants to eliminate that requirement and simplify the video calling process by building the feature directly into the device’s dialer.

Contacts that can receive video calls will have a small camera icon on them. “If you move back to LTE or Wi-Fi, switch it back to video with a single tap”.

“Of course there are apps that do video calling”, he wrote. Advanced Messaging supports a number of services, including group messaging, message delivery and read-mail notices, and the ability to send high-resolution photos and videos up to 10 MB. It will be accessible via a button in the dialer app when you’re calling someone who also has a supported phone.
