Following up on its recent buy-one-get-one (BOGO) free offer for the Samsung Galaxy S7, T-Mobile has rolled out a fresh BOGO offer for the iPhone.

Starting tomorrow, T-Mobile said any customer who purchases a new iPhone will get a second one half off when they add a new line of service. Both devices must be activated on equipment installment plans and the new line must remain active until at least July 15, 2016 for the deal to be valid, T-Mobile said.

The Un-carrier said the deal applies to the new iPhone SE as well as the iPhone 6s, 6s Plus, 6, 6 Plus, 5s and 5c. Those who have already pre-ordered the iPhone SE are eligible to take advantage of the offer as well, T-Mobile said.

T-Mobile said the half off savings will be granted for the lower priced device and will be delivered through a rebate card.

As previously reported, T-Mobile is offering the new 16 GB iPhone SE for $16.67 per month for 24 months and the 64 GB version of the device for $20.84 per month for 24 months.

Unveiled at the start of last week, the iPhone SE marks Apple’s return to a 4-inch smartphone in what it said was response to consumer demand. While aesthetically similar to the iPhone 5S, the SE comes with the improved A9 processor and M9 motion co-processor featured in the iPhone 6S. The SE also comes with a 12 mp iSight camera, a front facing retina flash, and the ability to shoot 4K video and Live Photos.

Preorders for the iPhone SE opened on March 24. The device will ship and become available in stores tomorrow.
