Does tiktok really see your sim card info?

If they really do , what will they see? the location or the actually sim card numberr?

I feel like its a stupid rumor becasue i don’t use sim cards and im able to get any country i want .

They have access to your location and what country your card belongs to, yes.

lets say i faked the gps and didn’t have a sim card in. that means it will go based off the location gps?
