Sprint is offering great iPhone 6s, iPhone 6s Plus and on iPads deals.

The U.S. carrier has started buy one get one (BOGO) deals on Apple's hottest smartphones and tablets. Current customers should be eligible for an upgrade and add one new line of service. New Sprint customers will have to add two lines of service.

"Buy one iPhone 6s or iPhone 6s Plus and get another one for free when you add a second line. Reqs installment billing for well-qualified customer with at least 1 new line. Service Credit applied monthly within 2 invoices," says Sprint.

Customers can purchase the 16 GB version of the iPhone 6s for $0 down and 24 monthly installments of $27.09. Customers will get the second iPhone 6s for free as Sprint will give $27.09 credit on the monthly bill.

Smartphone customers looking for a bigger phone can opt for the 16 GB iPhone 6s Plus for $0 down and then 24 equal installments of $31.25 per month. Customers will get a credit of $31.25 every month, which will make the second phone free. The Sprint BOGO offer is also valid if the handset is taken on a lease.

The iPhone 6s and iPhone 6s Plus sport top-end features, and they are still among one of the most popular mobile devices in the U.S. The latest offer from Sprint may tempt customers to purchase a new iPhone from the carrier.

Apart from the iPhone 6s and iPhone 6s Plus BOGO deal, Sprint is also knocking off $200 on the iPad Air 2, iPad mini 4, the 12.9-inch iPad Pro as well as the latest 9.7-inch iPad Pro.

"Get iPhone 6S or iPhone 6S Plus with lease or installment billing, and take $200 off iPads purchased with 24-mo. installment billing," says Sprint.

Customers who take advantage of the latest deal will have to pay $22.08 per month instead of $30.42 per month for the 9.7-inch iPad Pro. Similarly, the 12.9-inch iPad Pro will cost $28.33 per month instead of $36.67 each month.

This is not the first time Sprint has announced a BOGO deal on a top-end smartphone. The carrier also announced a BOGO deal for the Samsung Galaxy S7 in March this year.

Sprint is trying to entice smartphone enthusiasts with frequent handset deals. The carrier was also offering the new HTC 10 at a discount of $120, which reduced the price of the device from $624 to $504.

Sprint has not specified an end date for the iPhones and iPads deals. However, the carrier suggests that these are limited time offers.
