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 406-405 numbers is usually Mountain time. Scammers can also fake (spoof) any number, so a call that shows a 406-405 number may not come from Onvoy (Sinch) at all.
