Essential tips for selling your old smartphone

If you want to give away or sell your old smartphone or tablet, there are some important things you should do first. You don't want to accidentally pass on your personal information to someone else. We’ll explain how to clean up your device so it's good as new before it changes hands, and also suggest some places to donate or sell your device, if you are not sure what to do with your old phone.

1. Take out the SIM card

The first thing to do when preparing an old phone for a new home is to get your SIM card out. Even if you’re getting a new SIM with your new phone, your old one probably has lots of your contacts saved on it, so you don’t want to leave it.

You might need a SIM ejection tool to remove the card tray, but if you don’t have one, never fear, because we’ve already shown you how to open the SIM tray without it.

2. Unmount/remove the memory card

If you have a phone with a microSD card slot, then remove the SD card. Just look for the slot on the edge of your phone or behind the battery cover.

Before you remove the card, copy as many photos, apps, and documents as possible to it, so you can take them with you to your new phone easily.

3. Erase your data

The next thing to do is to wipe your data from the phone itself. There are two simple ways to do this: either go into Settings and look for the backup/restore section, or do it manually with hardware buttons. Make sure you have a full backup of all your data before you take this step!

Also, it is important to ensure you have signed out of your Google account (and Samsung, if applicable) before you wipe your phone. Otherwise, the person who receives your phone may not be able to activate it, since the device will be locked with your password.

How to backup your data on Android

The following data is deleted:

if you are getting rid of an iOS device, such as an iPhone, then the process is very similar. Again, make sure you have backed up your phone before you do this. Using iCloud is the easiest way.

Head over to your settings menu and follow these steps:

Navigate to General Settings.

Scroll down to the bottom and hit Reset.

At the top, you will see a couple of options. You want the one that says Erase All Content and Settings.

You will then need to tap on Erase iPhone twice to confirm.

Enter your Passcode followed by your Apple ID password to begin the erasing process.

4. Clean it

Once the insides of the phone are clean, the next thing you should do is clean the outside too. There might not be much you can do about scratches on the screen or general wear and tear, but you can sell it off without grubby fingerprint marks all over the display.

If you want to impress a potential buyer, you could apply a screen protector and replace the battery cover (if there is one).

5. Rebox it

If you’re a good Android owner, then you would have kept the box and bits and pieces that came with your old Android phone. Smartphones come with all kinds of goodies: from USB chargers and cables to headphones to SIM tools to spare earbud rubbers. The more of this stuff you can get back in the box (even if it’s not the original equipment) the more likely your old phone is to look well looked-after.

What to do with an old phone?

There are lots of different things you can do with an old phone:

Gift it to a friend or family member

Donate it to a worthwhile charity that breathes new life into old smartphones (such as Recycling for Charities, Cell Phones for Soldiers, or Green Citizen)

Recycle it (via your carrier, online, local agencies, or the EPA)

Sell it (either whole or for parts)

Trade it in for an upgrade 

Give it a new lease of life in one of these imaginative ways

Where to sell an old phone?

If you’ve decided to sell your phone, there are a few options: if the phone is in good condition (and you still have the box), the best place to sell anything secondhand is eBay. Get some nice pictures, fill in lots of details and upload that old Android or iPhone to the used marketplace. You also have the option of sites such as Swappa, Sell Cell, or Craigslist.

Beyond selling it online, there are also pawn shops, EcoATM, Cash Converters, electronics markets, garage sales, classifieds, and even the big retailers quite often have buy-back or trade-in offers.

The simplest thing to do is sell the phone back to the carrier you bought it from, but not all phones are accepted (especially very old or unpopular ones) and you aren’t likely to get top dollar that way.
