Both the S8 and S8 Plus are available in three colors — Midnight Black, Orchid Gray or Arctic Silver — and can be paid off through a 24-month installment plan for $30 down and $30/month for the S8, or $130 down and $30/month if you go for the S8 Plus.
From there, the magenta-tinted carrier will supply a rebate via prepaid card worth $750 to cover the cost of the extra S8 — essentially scoring you a free phone and potential high-end gift in time for Mother's Day (trust us, she'd appreciate the call.)
It's worth noting, however, that you need to purchase both phones at once on T-Mobile’s Equipment Installment Plan and add a line to qualify. Other fees like a $25 SIM starter kit or the cost of adding that extra line may also apply.
Should this sound like your kind of deal, you'll have to make haste. T-Mobile states that its buy-one-get-one-free deal on the Samsung Galaxy S8 is for a limited time only and subject to change.
We've asked T-Mobile to clarify exactly when its promotion might end, and will update this story as we learn more. In the meantime, you can visit T-Mobile's website, call at 1-800-T-MOBILE, or check an in-store location to learn more.
