AT&T is currently accepting pre-orders for the device and customers who are interested in purchasing it can add another handset and get that device for free. Note that this device won’t be free per se, but rather it will be reimbursed to customers over a period of time ($689 over 30-months for those who are curious).
This means you’ll still be out the cost of two devices, but eventually you will get the second device’s money back. However just like with the other BOGO promotions, this one is contingent on users signing up for a new line and a new contract with AT&T for at least one of the devices, not to mention that there will still be activation fees and relevant sales taxes to deal with.
However if you’re fine with this and if you do need a second device, then head on over AT&T’s website to place your order.
