Where to Trade In Samsung Galaxy S21, S22, and S23 Phones

If you’ve upgraded your Samsung phone in the last couple of years, there’s a good chance you’ve got an old Galaxy S21, S22, or S23 collecting dust in a drawer.

You’ve thought about selling it… But when you look around online, it feels like you’ve opened a can of worms.

Should you trade it in with your mobile carrier? Does Samsung offer a good deal? What about those marketplace sites or instant-cash kiosks? The promises of “top dollar” and “best value” are everywhere, but it’s becoming clear that many come with restrictive terms or disappointingly low payouts.

So to help you make the right call when you go to trade in a Samsung Galaxy S21-S23, we’re breaking down the best places to sell your old Samsung Galaxy and what you can realistically expect to get paid.

Why Your Old Samsung Galaxy Is Still a Hot Commodity

It’s easy to assume a phone that’s a few generations old has lost most of its worth, but the secondary market for premium Android devices is booming. In fact, high-end Samsung models (like the Galaxy S21, S22, and S23) are particularly sought after and continue to stay relevant long after launch.

This sustained demand is a core driver of the refurbished smartphone market, a sector valued in the tens of billions. These “old” phones are valuable pieces of technology that offer a premium experience at a budget-friendly price for their next owner, which means your device still holds real resale value if you choose the right place to sell it.

Trading in a Samsung Galaxy S21: Your Selling Options

When you do decide to sell your old Samsung phone, you’ll find four main pathways.

The most visible are the major mobile carriers like AT&T and Verizon, which advertise aggressive trade-in promotions. Then there’s the manufacturer itself, with Samsung’s own trade-in program. You also have do-it-yourself marketplaces (like Swappa and eBay), where you sell directly to another person. Finally, there are online buyback companies that specialize in purchasing used electronics for cash.

Each route offers a different balance of payout value, convenience, payment method, and security.

Here’s a closer look at how each option works.

The Carrier Trade-In: A Path of Hidden Costs

Trading in your old Galaxy S21 or S22 with a carrier like AT&T, Verizon, or T-Mobile is often pitched as the easiest option, especially when you’re already upgrading in-store. They roll out tempting promotions promising hundreds of dollars off a new phone when you trade in your old one.

However, this convenience is usually an illusion. Those high-value offers are almost always tied to signing up for their most expensive unlimited plans, locking you into a 24 or 36-month contract. The “value” you receive isn’t cash; it’s delivered as monthly bill credits. And if you want to switch carriers before your contract is up, you typically forfeit any remaining credits.

While it’s a simple process, it’s not the way to go if you want cash and if you want the very best deal.

Samsung’s Official Trade-In Program: A Closed Loop

Going straight to the source and using Samsung’s trade-in program is another option. The process is integrated into their online store, allowing you to get a credit toward a new Galaxy phone, tablet, or watch. It’s a trustworthy system backed by the manufacturer, so you can be confident your old device is handled securely.

But this route has two major drawbacks. First, the values for trade in Samsung Galaxy S21 phones are often conservative. Samsung’s primary business is selling new products, not buying used ones, so their offers are rarely the highest available.

Second, and more importantly, the payout is only issued as store credit. This locks you into their ecosystem, preventing you from using the money for anything else. It’s a decent choice if you’re a dedicated Samsung loyalist, but it offers zero flexibility.

Marketplaces Like Swappa and eBay: The DIY Route

If you’re willing to put in the work, selling your phone on a peer-to-peer marketplace like Swappa or eBay can yield a decent payout. On these platforms, you set the price, create the listing, and interact directly with potential buyers. This gives you full control over the sale.

However, that control comes with significant effort and risk. You are responsible for taking high-quality photos, writing a compelling description, answering buyers’ questions, and managing packing and shipping. You also have to factor in marketplace fees, which can take a sizable cut of your final sale price.

And even then, there’s no guarantee of a quick sale, plus you open yourself up to the risk of fraudulent buyers or disputes. This path requires time, effort, and a bit of luck.

Online Buyback Companies: The Smartest Way to Sell Samsung Phones for Cash

If your main goal is getting the most cash for your phone as possible (with the least hassle), using an online phone buyback company is the smartest option. These services specialize exclusively in buying, refurbishing, and reselling used electronics. And because this is their entire business model, they are structured to offer more competitive cash prices than carriers, manufacturers, or retailers.

Higher Payouts and Flexible Cash Payments

The single biggest advantage of using an online buyback service is the payout. Companies that specialize in the secondary market consistently offer more money when you trade in Samsung Galaxy S21 or newer models. Instead of restrictive bill credits or store credit, they pay you in actual cash via flexible methods like PayPal, Venmo, or a direct check. This gives you the freedom to use your money however you want.

A Secure and Streamlined Process

Online buyback companies also tend to follow a simple process that’s a lot less stressful than trying to sell your phone on a marketplace.

Here’s what that process typically looks like:

1. Get an Instant Quote: Answer a few questions about your phone’s model, storage, and condition to get an immediate offer.
2. Ship It for Free: If you accept the offer, you’ll receive a prepaid shipping label. You can then box up your phone and send it in without any cost.
3. Get Paid Quickly: Once the device is received and inspected, you’ll receive your payment.

The entire process is designed to be transparent and safe, with most buyback companies also performing professional data wiping to protect your personal information.

Making the Right Choice for Your Samsung Galaxy

Ultimately, deciding where to sell your old Samsung Galaxy depends on your priorities. If you value convenience above all and are already locked into a long-term contract, a carrier trade-in might be the easiest option. Or, if you’re a die-hard Samsung fan, their store credit might be appealing, too.

However, if your goal is to get the highest possible cash value, an online buyback company is the best way to trade in Samsung Galaxy S21, S22, and S23 phones. These services provide the best balance of high payouts, payment flexibility, and a secure, hassle-free process.

FAQs About Selling Your Samsung Galaxy

How much can I get if I trade in my Samsung Galaxy S21?

The value of a Samsung Galaxy S21 depends on its condition, storage size, and where you sell it. While carriers may offer promotional credits, online buyback companies often provide higher cash offers, sometimes up to $150 or more for a device in good condition.

Is it better to trade in my Galaxy S22 or sell it myself?

Selling your Galaxy S22 yourself on a marketplace might get you a slightly higher price, but it requires significant effort and comes with risks. For most people, using a reputable online buyback service offers the best balance, providing a high cash payout without the hassle of creating listings, dealing with buyers, or paying platform fees.

What is the best way to sell my Samsung phone for cash?

The best way to sell your Samsung phone for cash is to use a trusted online buyback company. These services specialize in the electronics market and consistently offer higher cash payouts than carriers, manufacturers, or instant-cash kiosks. They also provide flexible payment options like PayPal or direct deposit.

Do I need to wipe my phone before selling it?

Yes, you should always back up your data and perform a factory reset to wipe your personal information before selling your phone. However, most buyback companies will also perform a certified data wipe on all devices they receive to protect your privacy.

Can I sell a broken or damaged Samsung phone?

Yes, many online buyback companies, including SmartphonesPLUS, will buy broken or damaged phones. A cracked screen, broken camera, or other functional issues will lower the payout value, but the device is still worth something. It’s always worth getting a quote to see what you can get.
