We are receiving texts from a random number, how can we stop it?

Your texting numbers are just mobile phone numbers, and anyone can text in, just like your number. If you see a strange text, it's likely spam, a mistyped number, or something else.  

How can we stop it?

You can deactivate the user to prevent future messages (do this under Contacts).

Can we turn off all incoming texts from unknown numbers?

Yes! Mosio support can enable this for you. Please submit a support ticket and mention that you would like to turn off incoming texts from unknown numbers, and list your project ID and texting number.
