Why do I have unauthorized outbound SMS messages?

unauthorized outbound SMS messages

I'm having a strange problem with SMS on my M One 9. My phone suddenly started generating error messages about an outbound txt did not create. The message is:

122 Error Invalid Number

The number that the txt is trying to send to is +1121611611 (I believe country code 112 is Belarus).
I have no idea where this number came from nor did I create the message. Sounds like a hack. The message attempts to send itself periodically. I've tried deleting the whole thread but it comes back. Any suggestions?

unfortunately, it sounds like you should try a factory reset

You got it from some app (downloaded from untrusted site and sideload on your phone). Be careful with it. Did you check your bill now? Use sms blocker and let your carrier to know and block global that number. And sure factory reset.
