It's time to save big on the new iPhone 14. Nearly all carriers offer the iPhone 14 for free with a qualifying trade-in and unlimited plan. Plus, Best Buy and Apple have some generous discounts if you hand over a newer device.

The iPhone 14 lineup officially went on sale on September 16th. Note that iPhone 14 Plus pre-orders don't open until October 7th.

Apple: Save Up to $720 Off With Trade-In

Apple offers a pretty straightforward iPhone 14 trade-in discount. If you give up an eligible device, you could save up to $720 on your order. That's nearly the full price of a base-model iPhone 14. (You also get 3% cash back if you buy the phone with an Apple Card.)

Unfortunately, Apple won't give Android users a big discount. If you can't trade in an old iPhone, you may be better off buying the iPhone 14 elsewhere.

Best Buy: Save Up to $1,000

If you don't have an Unlimited plan with your carrier, Best Buy might give you the biggest iPhone 14 discount. It's offering up to $1,000 off an iPhone 14 with eligible trade-in and activation.

And to our surprise, Best Buy has a full list of all eligible trade-in devices. You can check this list to see how much money you'll get with a trade-in. (Best Buy will give you $350 for some very old Galaxy phones, which is interesting.)

Verizon: Unlimited Customers Save Big

If you're a Verizon Unlimited customer, you could save up to $1,000 on an iPhone 14. That means you could get the base-model iPhone 14 Pro for free. Verizon even accepts damaged phones for trade ins, so minor cracks or scratches won't hold you back too much.

Those who switch to a Verizon Unlimited plan get an additional $200 in billing credits. Plus, Verizon offers $120 toward a smartwatch when you buy the iPhone 14.

I should also note that Verizon has a new plan called "One Unlimited for iPhone." This unique Unlimited plan comes with a free Apple One subscription. That's Apple Music, Apple TV+, Apple Arcade, and iCloud+ at no charge.

AT&T: It's All About the Unlimited Customers

Customers on an AT&T Unlimited plan could save up to $1,000 on the iPhone 14 with an eligible trade-in. That means you could score the base-model iPhone 14 Pro for free. (According to AT&T, you'll get the $1,000 discount if you trade in a device that's usually worth $230 or more.)

Unfortunately, AT&T isn't offering any perks for non-Unlimited customers.

T-Mobile: Save Money With or Without an Unlimited Plan

Of all the major carriers, T-Mobile has the most generous iPhone 14 discounts. Customers on Magenta MAX can save up to $1,000 with an eligible trade-in. And all other customers can save 50% on their new iPhone 14 when they trade in an older device.

Also, T-Mobile is offering a cool "BOGO $700 off" discount. If you buy an iPhone 14 or iPhone 13, you can get another for $700 off!
