I have a new phone and the phone number seems to have been used before, by someone who wanted a notification whenever they logged in to Facebook.
Note: I do not have the phone that person had, so I can't go into the Facebook app or anything like that. I don't know their name, either.
I am getting texts at all hours of the day and night telling me "Your Facebook account was accessed from an unknown browser" etc. I want these to stop, but obviously I can't contact the person and say "you forgot to turn off your login notifications". How can I make these texts stop?
