Random MMS messages from "Unknown Address"

[Duffin]

This is really getting on my nerves. I randomly have been getting MMS messages from "Unknown address" which results in an empty message. Does anyone have any idea what is causing this?

What phone/tablet are you using?

Use a white list so only messages from your contacts will be allowed through. I use afree app called Black List in the Play Store as a white list and have never had an issue

I've been experiencing this as well. It randomly happens. When someone sends me an MMS, I get a message from "Unknown sender" that reads "message not found" at the same time. I learned this because the third-party app I downloaded, Textra, actually receives the MMS from the original sender.
