AT&T and Sprint are offering buy one, get one free offers on a wide range of the latest smartphones to new and existing customers who add a new line of service.

AT&T's offer, which is good through June 30, includes buy one, get one (BOGO) free offers on Samsung Galaxy S7 Edge, Samsung Galaxy S7, Samsung Galaxy S6, Samsung Galaxy S6 Edge, Samsung Galaxy S6 Edge+, Samsung Galaxy S6 Active, Samsung Galaxy Note5, LG G5 (pictured), LG V10, Microsoft Lumia 950, HTC One A9 and Kyocera DuraForce smartphones. The purchased phone and the free phone must be from the same manufacturer.

Sprint's BOGO offer is for iPhone 6s and iPhone 6s Plus handsets and is for a limited time, as well, but no end date for the deal has been announced.

AT&T's smartphone deal for a free phone must be through any AT&T Next device payment plan, with the free device being purchased specifically through a 30-month AT&T Next 24 plan, according to the company. Business customers can also participate in the BOGO program through a business Equipment Installment Plan (EIP) under an EIP 24 plan.

In addition, AT&T customers who also are customers of the company's DirecTV satellite television services can get unlimited data for four smartphone lines for $180 a month, after a $40 per month credit, according to AT&T. New customers are also eligible to receive up to $650 in bill credits per line to pay to switch them from their former carriers when they also trade in their old smartphones through the BOGO offer.

Both new smartphones must be added to a qualifying AT&T Unlimited Plan or a Mobile Share Value plan, which start at $70 a month for two phones on a Mobile Share Value, according to AT&T. The bill credits for the transfer fees are spread out over 30 monthly bill cycles. Taxes for both phones must be paid at the time of sale. The free device credits will also be paid out over 30 months.

AT&T business customers are also eligible to get $250 off eligible tablets with a two-year contract under the latest promotion.

Under the Sprint BOGO offer, buyers can get a 16GB iPhone 6 or a 16GB iPhone 6S Plus as well as a free smartphone of either model when they sign up for at least one new line of service when they have an eligible upgrade. The new phones can be purchased with monthly installments over 24 months or leased through 18 monthly lease payments. Customers can also purchase one of the devices and lease the other one under the offer, according to Sprint.

The deal means that buyers will receive a monthly credit for the monthly price of the least expensive device. They can get two of the same devices, or one of each model. The first iPhone 6s (16GB) is $27.09 per month with 24 monthly installment bill payments with $0 down ($650.16 total price), while the second one is free after a $27.09 per month service credit. The first iPhone 6s Plus (16GB) costs $31.25 per month with 24 monthly payments with $0 down ($750 total price), while the second one is free after a $31.25 per month service credit.

Sprint also offers a 30-day satisfaction guarantee for its mobile services, as well as reimbursements for switching fees from another carrier up to $650 per line.

Buyers of the iPhone BOGO deals can also get $200 off on a new iPad when they purchase it with their new handsets. The offer is good on any iPhone color and storage configuration when it is purchased on a Sprint lease or 24-month installment plan. Eligible iPads include iPad Mini 4, iPad Air 2, iPad Pro 9.7 and iPad Pro 12.9 in any memory configuration when purchased in 24 monthly installment billing payments.
