You can get a free Samsung Galaxy S8 from T-Mobile, but you have to act fast

If you're looking to go above and beyond for Mother's Day this year (and maybe treat yourself while you're at it) then now's the time to grab Samsung's latest phone.

T-Mobile has announced a limited-time promotion where if you buy a shiny new Samsung Galaxy S8 or S8 Plus on their network, you get another Galaxy S8 for free.

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 via T-Mobile’s Equipment Installment Plan and add a line to qualify. Other fees like a $25 SIM starter kit or adding that extra line may also apply.

Should this sound like your kind of deal, you'll have to act fast. T-Mobile has stated that the 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 will 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.
