Does the AT&T Samsung Galaxy S8 have dual sim capability?

[AC Question]

I just got the new Samsung Galaxy S8 on the AT&T network in the US and was wondering if it would have dual SIM capability, and if it would work overseas in Europe?

Thank you to all that answer, this is very important as I do not like to have two phones when i travel back and forth from Europe.

It will work with a Europe sim once unlocked but you can't have both at once.
