    Which phone?
    Which version of android?
    Which carrier?
    Which app is showing you the error/warning?

    Welcome to Android Central! More details always help, and that doesn't mean repeating yourself.

    Is this in a messaging app?

    So: a triangle with an exclamation mark inside it; and a triangle with an exclamation mark, presumably inside it, and ’MM’ under either the exclamation mark or the triangle.

    Both triangles and exclamation marks are conventionally used as warning symbols. So something - you haven’t said what - is trying to warn you of something.
