Android Malicious Text Messages

[Mrsmart180]

Hi guys, tonight I got 3 of these messages from this unknown number, and I downloaded one out of curiosity but as soon as I downloaded it, it disappeared. I have a picture of the other 2 and I was wondering what it was. I ran 2 different antivirus scans and I'm pretty sure I'm safe because everything is up to date, but I really want to know what this is and how you can even send anonymous texts because I didn't think it was possible. Also is there any reason I specifically would receive these texts? When I got them it froze my entire texting app so my messages wouldnt send so that's mostly why I am so curious. Thanks.

Someone sent you voice messages nothing to be concerned about.
They could be from someone you know or not.
I'm leaning towards not, but if it came from an unknown number just delete them.

Possibly a scammer casting a net for victims, to see who responds. Don't respond. Delete, block... just don't reply or you may be deluged with spam texts.
