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.
Unfortunately, videos sent on iOS will not have audio.
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 firstname.lastname@example.org if you need any help!
