T-Mobile is currently running a promotion that lets you purchase a qualified Apple, Samsung, or LG smartphone and get 50% off the second device. Appropriately dubbed Buy One Smartphone, Get One Half-Off, the promo can only be availed by making a call or heading to a local T-Mobile store.
Eligible devices include the Apple iPhone 6 and above, the Samsung Galaxy S6, S6 edge, Note5, S6 edge+, as well as the LG G4 and V10. An important thing worth mentioning here is that the second device being purchased should be of equal or lesser value and from the same manufacturer as the first one.
The Magenta carrier notes that it's a limited time offer, although it doesn't exactly specify when the promotion ends. Also, the deal is subject to the availability of devices.
