About the 310-421 exchange
310-421 is an exchange (the first six digits of a phone number) in area code 310, which covers California. NANPA, which runs the North American Numbering Plan, assigned it to T-Mobile for the Redondo Beach, CA rate center. 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 310-421 numbers is usually Pacific time. Scammers can also fake (spoof) any number, so a call that shows a 310-421 number may not come from T-Mobile at all.
