AT&T's got a new iPhone X Buy One, Get One deal, but it'll only be available for a limited time.

Starting today, June 15th, you can get an iPhone X for free from AT&T when you buy an iPhone X. This offer is available to new and existing customers and will end on  June 19th.

To qualify for this deal, you'll need to buy both iPhone X models on AT&T Next or AT&T Next Every Year. The first phone can be purchased as a new line or an upgrade, but the second phone must be a new line. Also of note is that you'll need to pay the tax on both phones at the time of sale.

Once you meet all of these requirements, you'll get $999.99 spread out over 30 monthly bill credits to cover the cost of the second iPhone X. The credits will begin in three billing cycles or less.

The iPhone X is one of the best smartphones on the market, but it's also one of the priciest devices. That makes this AT&T deal pretty great if you and your partner, family member, or friend both have your eyes on a new iPhone X. Just keep in mind that because the credits for the second phone are spread out over 30 months, you will need to remain with AT&T for that entire time if you want that second iPhone X for free.
