MMS is not supported

Does EZSMS support MMS messages?

No, EZSMS can send SMS but not MMS.

By the way, what is the difference between SMS and MMS?

SMS - Send to a Mobile Phone Number - Send only text messages - As SMS stands for "Short Messaging Service", there is a limited number of the text per message

MMS - Send to an email address (of the mobile phone carriers) - Send text messages as well as images and emoji - Usually no limits on the message text length

About the text length limit for SMS messaging, please also refer to:
