AT&T is offering a holiday deal, where you can get two smartphones for the price of one. That does sound too good to be true, and it's mostly because it is, though there likely are those that can take advantage.
The offer extends to popular models like the Samsung Galaxy S6, as well as the carrier exclusive Galaxy S6 active, but also the current iPhone 6s. For a precise list of participating models, you'd best contact AT&T, but from what we gather, you can't pick up one iPhone and one Samsung, the two smartphones need to be the same brand.
Either way, the terms and conditions are pretty complex, but the essence is that both devices need to be on a Next 24 plan upwards of $70/month (which in fact means a 30-month subscription). Then after three bills, AT&T will start waiving the monthly payments for the phone for the next 30 months for a total of $650 (or $21.67/month). The free device needs to be a new line, and the other one can be a new line or an upgrade.
The offer expires on December 31, so if you happen to be eligible and are at all interested make sure you act by the end of the month.
