If you’re planning to upgrade your smartphone but wary about a steep price tag, trade-ins are a great way to knock down the cost. Companies like Apple and Samsung can discount hundreds of dollars (depending on your phone model), and most importantly, save you the hassle of reselling by letting you exchange your phone toward a new one.

However, the process of trading a smartphone can be daunting, especially if it’s your first time. We’ve compiled a step-by-step guide to help you get the highest-value discount off your next smartphone.

Before you start packing your phone for shipment, it’s important to identify the condition that it’s in. Are there visible scratches? Does it turn on? Are there cracks? Depending on the condition, trade-in programs will offer you more or less of a discount — in some cases, nothing at all for ones that are just … unusable.

Here’s a checklist most companies require for trade-ins:

If you satisfy the requirements, inspect your device for cracks, scratches, and dings — the less there are, the more value you’ll get out of the phone. It helps to take pictures and videos of your phone with an emphasis on any wear and tear, in the case that there’s any unexpected damage during the shipping and handling process.

There are a ton of companies who are willing to offer you discounts or store credit for your phone, but choosing the right one is crucial if you want to get the most bang for your buck.

Here are the trade-in programs we recommend:

It should come as no surprise that Apple is the best place for trade-ins if you have an older iPhone, but it’s more than just a game of match. Apple’s trade-in program continues to expand and offer generous discounts for used iPhones, and it offers free consultations if you trade in directly at the store. If you decide to ship your phone instead, a prepaid shipping label is provided. The trade-in value of your device can go toward a future purchase or an Apple Store Gift Card, which never expires.

Samsung offers some of the best trade-in values for Android and iOS devices, especially if you’re eyeing a new Galaxy smartphone. In the past, trade-in values have gone up to $700 — one of the highest rates we’ve seen — and you’re able to apply the discount toward a new phone before you even ship out the old one. We also recommend Samsung for its occasional cracked-screen offers. While most trade-in programs don’t accept cracked screens as they’re deemed unusable, Samsung gives you a fixed quote no matter what device you’re sending in.

Perhaps you’re undecided on what device you want to upgrade to or just want some quick cash. Gazelle is a site that buys and sells phones, but unlike eBay and Craigslist, the company offers no-fuss transactions. All you need to do is state the condition of your phone (honestly) to receive a set quote, and ship it out to get paid.

Here are a few other options worth considering:

Once you’ve settled with a trade-in program and upgraded to a new phone, it’s time to back up and transfer your data. Below are some guides we’ve written to help you with the procedures.

To transfer your data from one phone to another, check out our guides below:

When all your files are backed up and transferred, turn your old phone off and remove any SIM and MicroSD cards from the device. Turn it back on and if it’s at 50% battery or higher, you’re ready to factory reset the phone.

Factory resetting can seem like a one-step process, but it’s vital that you fully clean out your device so there’s no personal information left once it’s out of your hands.

The steps will differ depending on which brand you have. However, there’s only a slight variation, and you should still be able to factory reset your device by following the instructions.

If you’ve successfully backed up and wiped your phone, it’s time to pack and ship it out for evaluation. Though the inspection is up to the trade-in program itself and may take a couple of business days or longer, there are some simple measures you can take to expedite the process.

It goes a long way if your phone is well charged and will save the inspector some time when examining it — anything higher than 75% will suffice. Make sure the device is powered off when packed as you don’t want it to run idle and slowly drain itself throughout the shipping process. Ideally, you’d want to ship your old phone in the box that it came with. Smartphone boxes are designed to keep the phone inside safe and protected from any damage during transit. If you can’t find it, sealing the device inside a padded envelope works as well. Since most trade-in programs only require you to submit the phone itself and not with the accessories, you shouldn’t have any trouble packing the phone nice and snug.

As for shipping carriers, the return label that trade-in programs provide for you should have one selected already. It’s best if you stick with it as the label most likely has a return merchandise authorization (RMA) attached. If you decide to ship with your own label, choose a carrier that offers tracking and insurance (if you want to be extra safe). Just make sure you leave a slip inside the box that states your name and order information, so the inspector knows who the phone is from.

Once the phone is delivered, it can take up to a month for the trade-in program to fully inspect it. Be patient, and enjoy your new upgrade.
