My son recently got a new Tracfone with the new phone number. Every time I attempt to send him a text via Messages on the OS X desktop, it automatically picks his old number. However, this number has been deleted from his information in Contacts. I’ve purged it from everywhere, yet it still shows up, along with his new number. How do I permanently delete the old number?
PS. To make matters worse, someone else now has that old Tracfone number and I keep texting them accidently. Oops!
