PSA: The cheapest Samsung Galaxy S8 can be found at Boost and Virgin Mobile
Both Boost and Virgin Mobile are offering the Samsung Galaxy S8 only in black, with no carrier branding to be found anywhere on the phone. It appears that the handset can be unlocked for free, but only after using it for at least 12 months on Boost or Virgin. You'll have to pay $649.99 for the phone, wait for it to arrive to your house (if you're not getting it from a brick and mortar store), then activate it online and choose a pre-paid monthly plan starting at $35 per month. More details can be found at the source links below.
So, is anyone willing to buy the Samsung Galaxy S8 from Boost Mobile or Virgin Mobile?
P.S.: In case you are wondering, Boost and Virgin Mobile do not sell the larger Galaxy S8+ (which would have been more expensive anyway).
