Samsung's new phablets -- the Galaxy Note 5 and the S6 Edge Plus -- are now available for preorder. But unlike an iPhone, prices vary widely between carriers, ranging from $250 with a two-year commitment to more than $900 for an unlocked model.

Take a quick peek at a U.S. carrier's website and you'll find tons of plans and incentives to draw you in. Some offer trade-in credits and others throw in a free tablet -- making the decision process a little more complicated. So before you run out and preorder the Galaxy Note 5 or S6 Edge Plus, here's a look at the options available from major U.S. carriers.

If you're the customer who prefers to pay for their device in full, T-Mobile offers the lowest full retail price of the four major U.S. carriers. Alternatively, customers can also opt for the company's various installment plans, including its "Jump On Demand" service, which lets customers trade-in their smartphone and upgrade to a new device without a waiting period or additional fees.

As an extra incentive, customers that pre-register to purchase the Note 5 or S6 Edge+ via T-Mobile's website will also be eligible for a free one-year subscription to Netflix with purchase.

Under a two-year contract with AT&T, customers can purchase a 32GB Galaxy Note 5 starting at $249.99 or the S6 Edge+ at $299.99, one of the cheapest deals available for the phone. Alternatively, the carrier offers various payment plans, including AT&T Next, which allow customers to upgrade to a new device after a certain number of paid installments.

Verizon Wireless
With Verizon ditching two-year contract deals, its prices are fairly straight forward. Customers can either pay for their preferred Samsung device in one go, or hop on to a 24-month equal payment plan. For a little extra savings, the carrier is also offering $200 in the form of a Verizon Wireless gift card for trading in a smartphone.

If you're comfortable with not owning your device, Sprint offers a leasing plan where you return it after 24 months. The carrier is also offering $200 trade-in credit and a free Galaxy tablet with a new two-year contract.

The Samsung Galaxy Note 5 and S6 Edge Plus officially go on sale Aug. 21, following the preorder period.
