Unlocked Samsung Galaxy S8 and S8+ will be launched on May 316
Apparently, the only authorized locations to sell unlocked S8 units are Best Buy stores and Best Buy's website - in addition to Samsung's own US website. This explains why you may be seeing unlocked S8 and S8+ phones offered by other retailers at higher prices.
Speaking of prices, an unlocked Galaxy S8 costs $724.99, while the unlocked Galaxy S8+ is offered for $824.99. Both smartphones are already available to pre-order from Best Buy and Samsung, coming with a free Entertainment Kit (including a Clear View cover, a 64 GB Samsung EVO+ microSD card, and six months of Netflix).
So, do you plan to get yourself an unlocked Samsung Galaxy S8 or Galaxy S8+?
