T-Mobile phone?
If yes then TMO rolled out an update for its messaging services so far as i know those features only work with tmo to tmo and the other tmo user has to have a phone that has the update and supports it.

the message in your screenshot says that video call can not be made to that number so the person you are calling does not have a video call capable device or their network does not allow it
