The Galaxy S8 and S8+ will be available unlocked at $724.99 for the Galaxy S8 and $824.99 for the Galaxy S8+. Alternatively Microsoft’s online store will also allow customers to purchase either the AT&T or Verizon mode of the phone, where interestingly enough Verizon’s model will cost you slightly more.
It should be noted that if you were to purchase the unlocked models, you will be eligible for a $150 discount as part of Microsoft’s Black Friday promotion, so that’s something to consider, plus there’s also the fact that you will be free from any obligations to carriers and be free to pick any carrier of your liking.
However the Black Friday promotion only kicks off on the 23rd of November, so you’ll probably want to wait until then to take full advantage of it.
