About the 707-355 exchange

707-355 is an exchange (the first six digits of a phone number) in area code 707, which covers California. NANPA, which runs the North American Numbering Plan, assigned it to T-Mobile for the California 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 707-355 numbers is usually Pacific time. Scammers can also fake (spoof) any number, so a call that shows a 707-355 number may not come from T-Mobile at all.
