One of the nicest things about Android is just how many upgrade options you have throughout the year. Whether you're ready to try out a folding phone or want some extra performance with a gaming phone, the only obstacle is the cost. Selling your old phone can help you get as much as possible for it while also giving you time to get your data off of it. Furthermore, it's better for the environment to use phones for as long as its still working fine.

We're going to show you some of the best practices for preparing your Android phone or tablet for sending off, as well as show you some of the best places to sell or trade in that old device.

Properly clean your phone

We carry our phones with us nearly everywhere and it's safe to say, just about every germ that has touched our hands has reached our phones. We recommend you keep up with good sanitation practices for your phone even when you aren't preparing to sell it, but as you're getting ready to move on to something else, it's especially important that you give your old phone a good and thorough cleaning. 

Germs and viruses are tricky little buggers, with some of them being able to live on certain surfaces (like your phone) for longer than you might expect. People take their phones with them nearly everywhere, making them a petri dish for all of the germs you encounter each day. If you haven't taken your case off in a while, you could be surprised how much stuff gets trapped under it.

Not only that, but you really shouldn't sell someone a phone with all of your fingerprints, smudges, and other gunk covering it — it's just gross. Even a used phone is a big purchase and the buyer deserves to feel like they're getting something that feels fresh, clean, and new.

When you buy a phone, even a used one, it's much nicer when it comes out of the box looking fresh and clean.

As such, we strongly encourage you to clean and disinfect your phone before shipping it out. You can go all out and buy a phone cleaning kit or keep things simple with disinfectant and screen wipes. Try to keep liquids out of the charging port and make sure the phone is dry before packing it up.

Remove SIM and SD card

While eSIM has been around for a few generations now, most phones from the last few years still use a physical SIM to get connected. A SIM is a small memory card that stores all of the information a phone needs to connect to your carrier's network.

If you're simply moving your service from your old phone to your new phone, you can swap the SIM directly into the new phone. Not everyone is excited for the move to esim, and carriers aren't making it any better. If you do decide to switch to eSIM, take your old SIM out of your phone before you send it off. The buyer will need to bring their own SIM anyways.

Often you'll need a SIM ejector tool to open the SIM tray; the exact method will vary by device, but you likely remember where it is from when you bought the phone. Your new phone will more than likely have one in the box as well.

Not every phone or tablet will have an SD memory card slot, but if it does, you'll often find it alongside your SIM. Memory cards can store your photos and music, though the device itself has its own storage too. Use either your phone's native file manager or a third-party one (we like Google's Files app) to look in the folder where downloads, music, and photos may have been saved. From there, you should be able to copy them to your SD card before removing it.

A lot of newer phones don't accept SD cards and there's a good chance your new phone will have plenty of onboard storage to transfer all of your data to it.

Back up data

Assuming your data is associated with your Google account, then your contacts, calendar, and email will already be fully backed up in the cloud. That means that when you fire up your new phone, that important information will be there as soon as you log into your Google account.

If you've already transferred most of your content to your new phone, you might not need much from your old phone. If you don't want to immediately bog down your gallery with your old photos, Google Photos can keep a copy on the cloud. You'll be able to access and download your pictures from the Google Photos app whenever you want.

If you'd rather not go through the cloud, your device manufacturer may have desktop software that would allow you to back up your data with a USB cable. But, again, that process will vary by who made your phone or tablet. Samsung's Smart Switch will even allow you to back up to external storage in addition to a transfer directly to your new phone, provided that the new phone is made by Samsung.

Passwords can (and should) be backed up using a centralized password manager, but Google also has a built-in password manager tied to your Google account that will auto-fill usernames and passwords both in apps and on the web in Chrome. Smart Lock goes a step further and saves all of that information on a per-app basis; this happens automatically whenever an app supports Smart Lock.

As for apps, this is a tricky one. A handful of apps use Google's backup service to keep everything synced to your Google account and will re-download with data intact on your new phone. Unfortunately, these are few and far between — but there's a larger group of apps that will keep things synced on their own cloud service based on your login.

If you're using an authenticator app, one of our preferred two-factor authentication methods, you should also makes sure to get it set up on your new phone before performing a factory reset. You'll need some of those codes when you're setting up your new phone, so it's good to keep them handy.

Unlock your phone

If you've paid off your phone, there's a good chance you don't need to do anything else to unlock your phone. Unlocking your phone means SIM cards other than those of the original carrier can be used. Increasingly, phones are unlocked by default if you buy them outright, but if you're financing your phone through your current carrier, you'll need to be careful and understand the terms and conditions of having it unlock your phone.

For example, a T-Mobile phone should be a good fit for Mint Mobile or another T-Mobile prepaid carrier. It's not guaranteed, especially with older phones, but sticking to the same core network is the best bet. In many places, carriers will use multiple different bands, so if your new phone doesn't support all of them, you may still get acceptable performance.

Unlocking your phone often adds value to your phone since it can work on other carriers around the world.

So, where do you go to unlock your phone? Most carriers in the U.S. should unlock your phone for you; assuming you bought the phone from that carrier, your account is in good standing, and you've had it for around 40-60 days (this varies from carrier to carrier). You may need to contact support or simply fill out an unlock request online. This should only take a few days at most to complete and should be done before you deactivate the phone.

If you still owe money on the phone, you have to pay it. Many people buy phones on 24 or 36-month payment plans so you may still owe some money on your current device. You may also have discounts associated with that payment plan, so find out just how much you'll need to pay from customer service before activated your new phone.

Factory reset

Once you're sure your data is safe and secure, you're ready to wipe it clean by performing a factory reset. The first thing you'll want to do is turn off Factory Reset Protection (FRP), which is an extra security measure in case your phone or tablet gets stolen and the thief simply does a factory reset on it.

FRP can be disabled by removing your Google accounts from the phone or tablet. Jump into Settings and find Accounts. You'll see a list of various accounts you've set up on the device, but you want to tap on Google. Here, you'll see your Google account(s), where you can tap on them and see more settings to remove them permanently.

In the Settings section for most phones, you'll find an option for Backup and Reset under System Settings. If it's not immediately visible, the settings menu should have a search bar to help you. You'll want to double and triple-check to make sure all of your important information has been recovered from the phone because, after this, there's no going back.

Gather accessories

With your phone storage wiped clean, you'll want to gather all of the miscellaneous odds and ends you have sitting around. If you still have the original box, receipt, and warranty, those are all good to include. The original USB cable, wall charger, SIM ejector tool, and headphones (particularly unused ones) are nice bonuses. If you want to put the real icing on the cake and increase your chance of sales, include any relevant third-party accessories. The case, in particular, as you won't have much use for it after it's gone anyway.

Clean device and take pictures

Give your phone or tablet a good wipe down with a microfiber cloth, and get ready to take some pictures. Use a proper camera (i.e., not another phone) with a tripod if you have one. Your top priority for taking pictures is good lighting. A lamp will cast a lot of shadows, but if you have a cool-toned halogen overhead light in the house somewhere, that should provide a nice even look.

Keep the background clean. Even if you're just putting the phone on a white piece of paper, that's fine. Get multiple angles, and if there are any particular scuffs or shows of wear, photograph them.

The buyer will want to check for scratches or blemishes and avoiding showing off your phone could push people away from your listing. It could also lead to a customer requesting a refund if they feel the condition of the phone was misrepresented.

Sell your device

With your phone wiped and cleaned, and the accessories all boxed up, you've got to figure out where to sell. Your venue of choice will often decide how much of a return you'll get.

Carrier trade-in

Finding a buyer can be a hassle, but all major U.S. carriers (Verizon, AT&T, and T-Mobile) will generally offer you some credit for your old phone. A resurgence in many guaranteed upgrade plans requires you to hand your old phone back before being able to snag a new one. Though this is a pretty convenient solution, especially if you intend on sticking with your carrier for your next phone, the actual return on your phone will likely be less than through other venues for sale.

You can also skip the cleaning and photography steps by going to a carrier. The carrier employees could even help you with data tranfers.


Most major mobile carriers give customers the option to trade in their old phone and receive a credit that can be put toward the purchase of a new phone.

Amazon trade-in

Amazon's trade-in service applies to just about every type of phone, tablet, and electronic product. Amazon will pay for shipping your device out to them, but you'll get paid with an Amazon gift card rather than proper cash. This can work out in the long run as many of the best Android phones are available at Amazon. However, if you just want some cold, hard cash or already have your next device ready to go, this route might not be for you.


Amazon's Trade-In program provides customers with an Gift Card in exchange for trading in a variety of gently used devices, including cell phones.

eBay is a massively popular way to sell your stuff. A rating system vets sellers and you can pay in several secure ways. You'll need to deal with additional fees and the hassle of shipping, but a much wider audience will see your device for sale here than just about anywhere. There are a few things to keep in mind before jumping onto eBay:

  • Only ship to the confirmed PayPal address if that's how you're getting paid. This ensures you keep PayPal Seller Protection.
  • Price competitively. It's easy to check other sales of the same item and see how much they've sold for. With a larger seller pool, it's easy for buyers to find cheaper options.
  • Be honest about the condition of your Android device. If the phone arrives in worse condition than the listing suggested, the buyer can get their money back.
  • Use accurate keywords in the title and description. That means full market name, model number, carrier branding, memory denomination, and a mention of accessories included.
  • Mention shipping details in your description. Usually, the faster the shipping, the better, even if it bumps up the cost of the device, and insurance isn't a bad idea. Communicate regularly with your eventual buyer about the shipping status of the device.
  • Avoid low-feedback buyers. Odds are it's for a reason, and you can often drill down into their feedback profile to see any previous altercations a buyer has had on eBay.

eBay's mobile resale section includes a rating system that vets sellers and allows customers to pay for devices in several secure ways.

Craigslist or Facebook

Use Craigslist or Facebook to sell your Android device locally, which cuts out the issue of shipping. Of course, any potential buyer will want to check out the condition of your phone in person before handing over any money. Some sellers might not be comfortable meeting strangers and taking their money, but it's a fairly common occurrence. So long as you follow some simple guidelines, everything should go fine.

  • It should go without saying but don't post your home address or phone number in the public Craigslist ad.
  • Price competitively by monitoring how much similar devices are selling for. You'll have a hard time moving yours if potential buyers know they can get a better deal.
  • If interested buyers want to call on the phone, consider using Skype or a temporary phone number to maintain privacy.
  • Meet in a public place during the daytime. Most buyers are going to be perfectly normal and friendly, but better safe than sorry. Some local police departments have set up monitored Craigslist exchange spots. If this is an idea, you can search for a safe deal zone near you.
  • Shipping internationally or getting offers that are absurdly higher than your asking price are signs of a scam. Hold off for a legit offer and only make cash deals.

Craigslist users can buy or sell gently used phones within their region via the cell/mobile tab, which is located under Services.

If you're a Facebook user, Facebook Marketplace is another good pick. Its massive user base can put a lot of eyes on your product making for a quicker sale. It's also nice that you can handle all messaging through Facebooks's messenger which can block messages about the listing as soon as your mark it sold.
