TextMe users are able to send both pictures and videos to other TextMe users. However, some non-TextMe users may experience some issues with sending or receiving to/from a TextMe user. You should be able to receive most pictures and videos from Verizon, Sprint, and AT&T users.
Please invite your friends to try TextMe which will allow you to send pictures and videos without any issues. Feel free to send a message to support@go-text.me if you need any help!
