About the Galaxy S21 Ultra

The Galaxy S21 Ultra was released in 2021 alongside the Galaxy S21 and S21+. It carries on the Samsung tradition of packing the most exciting and premium design innovations into its biggest (and most expensive) device. In this case, the Galaxy S22 Ultra features a large 6.8-inch Dynamic AMOLED display, a versatile quad-camera system, and a massive battery for long-lasting usage. All of this is powered by a Snapdragon 888 chip, delivering a fast and smooth premium smartphone experience.

Why you should trade in your Galaxy S21 Ultra

While impressive in its time, at four years on rhe S21 Ultra’s camera, battery, and AI capabilities can’t match what’s available now. Trading it in for a Galaxy S25, Pixel 9, or iPhone 17 will keep you on the cutting edge. Verizon, AT&T, and T-Mobile accept the S21 Ultra for trade-in.

Trade-In Process for Popular Devices

Trading in your phone for a new one is as easy as one-two-three. Whether you’re trading in an Apple iPhone, Samsung Galaxy, Google Pixel, or another kind of Android device, rest assured that there’s a trade-in program for you.

1. Calculate Your Phone’s Value

Calculating your phone’s value will help you determine its eligibility for various trade-in offers. Navi’s trade-in value calculator on this page can give you a ballpark of what your phone is worth to get started. Ultimately, you’ll also need to assess your device condition and have your IMEI number on hand, as all of these factors impact the value of your trade-in credit.

2. Choose an Offer

Once you’ve gotten a ballpark estimate of your phone’s trade-in value, the fun part begins: choosing the trade-in promotion that suits you best. Most phone trade-in deals provide bill credits spread out over 24 or 36 months. These credits are applied to your monthly bill, lowering the cost of a new phone over the installment period.

3. Prepare Your Device

Now that you’ve calculated your phone’s value and chosen a trade-in offer, it’s time to prepare your device. First, you’ll want to perform a factory reset of your phone. Next—assuming you’re mailing your device in as opposed to doing an in-store drop-off—you’ll need to prepare your phone for shipment. Print the shipping label, box your phone up, and send it off. You’ll have your new phone in no time.

Trade-In Requirements

In order to trade-in your phone for a new device, it has to meet certain requirements. These tend to be the same regardless of which carrier, third-party reseller, or retailer you go with. They include:

Ownership

You must own your phone outright in order to get the max trade-on value for it.

Functional Condition

While requirements can vary, generally speaking your phone should power on and hold a charge, have a crack-free, functioning screen, and be free of water damage.

Factory Reset

Make sure to erase your personal data and reset your phone to factory settings before trading it in.

Physical Condition

While many programs accept phones with slight cosmetic wear, just be aware that it may reduce its trade-in value. Major physical damage (cracked screen, missing buttons, bent chassis) may disqualify it or lower the offer.

Model Eligibility

The device you plan on trading in must be a model that the trade-in program accepts. Older models may not qualify.

While trade-in offers generally require the above, carriers occasionally run Any Phone, Any Condition promotions which waive many of the aforementioned requirements.

How to Find Your IMEI

In order to trade in your device, you’ll need to provide its IMEI number. There are a few ways to do this.

Dial *#06# on  your phone

The IMEI number will be displayed on screen.

Access the Settings menu on your phone

Pull out the SIM card tray

The IMEI code may be printed on the tray.

Look at your phone’s box

The IMEI number should be on a sticker attached to it.
