About the 636-331 exchange
636-331 is an exchange (the first six digits of a phone number) in area code 636, which covers Missouri. NANPA, which runs the North American Numbering Plan, assigned it to T-Mobile for the Missouri rate center in 2017. Numbers from this carrier are usually wireless (cell phone) lines.
People keep their number when they move or switch carrier, so this is where the number was first assigned, not where the caller is today. Local time for 636-331 numbers is usually Central time. Scammers can also fake (spoof) any number, so a call that shows a 636-331 number may not come from T-Mobile at all.
