Frequently Asked Questions
How do I know what my Galaxy S8 is worth?
We want you to be happy with your offer from GadgetGone. So before selling your Galaxy S8, it’s a good idea to get multiple price quotes to make sure you’re getting the best trade-in value for resale. Aside from getting your instant GadgetGone offer, a great way to assess the potential value of your used phone is by taking a look at your phone carrier’s trade-in program.
You can also look at other popular buyback programs like gazelle.com or buybackboss.com to get an idea of what your Galaxy S8 is worth. If you find a better price from any of these companies, GadgetGone will beat it with our PriceMatch+ Guarantee. Just message us to let us know the company you’d like to price match.
Remember that condition is very important when it comes to cell phone values—you’ll always get more money for a phone in excellent or good condition.
Can I sell my old Galaxy S8 even if it’s broken?
Yes! GadgetGone accepts phones in a variety of different conditions, from brand-new to broken. We’re the best place to sell your broken cell phone because unlike other trade-in sites, we’ll pay you a fair price.
Have a phone with a cracked or damaged screen (or even cracked backglass) that works perfectly otherwise? Don’t settle for lackluster offers from one of our competitors. Select our special “cracked” condition category and get paid more than with any other buyback program. You can even sell old cell phones that are water damaged or won’t turn on. No matter the issue, you’ll always get the most cash by trading in your cracked or broken phone with GadgetGone.
Can I sell a locked cell phone?
That depends on what you mean by “locked.” While you can sell your carrier-locked phone to GadgetGone, we do not accept used cell phones that have been reported as lost or stolen. You can trade in a phone that is still being financed to GadgetGone as well. Just make sure you select the “broken” condition category when getting your instant quote.
Can I sell more than one cell phone?
Definitely! Heck, you can sell devices of all kinds to GadgetGone, not just cell phones. Whether you have multiple phones of the same model or a bunch of different models, you can add any quantity necessary to your cart when getting your initial quote. We even accept bulk trade-ins from wholesale sellers or companies looking for IT asset recovery.
Does it matter who my carrier is?
Not at all! GadgetGone offers instant quotes for cell phones from major carriers like AT&T, Verizon, T-Mobile, and Sprint (and of course you can sell unlocked phones, as well). If you need to sell used cell phones from a lesser-known network carrier (like Xfinity, Cricket, Straight Talk, Tracfone, US Cellular, or others) just contact us for a custom quote.
Do I have to sell my cell phone after I get a quote?
Nope! All of our quotes are obligation-free. You don’t have to ship your phone unless you’re happy with the amount we’ve offered. And if for some reason you change your mind after sending it in, we’ll mail your used cell phone back to you for free—no questions asked.
How long do I have to ship my old cell phone?
Your quote is locked in for 14 days from the time you check out on our website. As long as the USPS tracking number shows you shipped your cell phone within those 14 days, your offer amount is guaranteed.
You can still ship your phone after the 14-day price-lock period (some of our customers wait 30 days or more); however, your phone will be subject to whatever our current pricing is at the time of evaluation. Earlier is always better, but feel free to ship your cell phone whenever you’re ready to sell!
What do I need to do before selling my Android phone?
Unsure of how to prepare your old Android phone for selling? Just follow these easy steps:
1. Back up your cell phone. Chances are that your Android phone is already set up to back up your phone’s data automatically using your Google account. However, it’s a good idea to back it up one final time before you sell it. Do this by going to Settings > System > Backup > Back up now > Continue. If you have a Samsung phone, back it up by going to Settings > Accounts and backup > Backup and restore > Google Account > Back up now.
2. Turn off Factory Reset Protection by going to Settings > Accounts/Accounts and backup > Accounts > find and tap on your Google account(s) that is tied to your phone > Remove account.
3. Factory reset your phone by going to Settings > System > Reset options > Erase all data (factory reset) > Reset phone > enter your device’s passcode if necessary and select Continue > Erase everything. If you have a Samsung phone, factory reset it by going to Settings > General management > Reset > Factory data reset > Reset > enter your device’s passcode and select Next > Delete all.
4. Make sure your cell phone has been paid off and removed from your carrier account if necessary.
5. Fully charge your phone, then turn it off.
6. Remove your SIM and SD cards if you’d like to keep them for another device.
