Who called from 4156898849

Got a text message "Lookout is sending this message to initiate an automatic connection. No action is required FLXHvoT25". I do not have the app on my phone so I blocked. Got same text from another number as well.

Lookout is sending this message to initiate an automatic connection. No action is required. LKO3omY29

What does this mean?
I've received similar texts that appear to be coming from my sons phone number, not this number
