How to sell your old Windows Phone

While Microsoft hasn't been doing well on the phone market, it doesn't mean that the platform isn't any good. Windows phones are great devices with very capable software -- perhaps the platform just need the right push to get more developers and customers actually using the handsets.

And this "right push" might come sooner than we think as things may start to change on October 6th, during the company's huge hardware event in New York City. Microsoft is expected to launch some new handsets running Windows 10 Mobile.

After numerous rumors and information leaks, we know the software giant will be introducing new Lumia phones, including the Lumia 950, Lumia 950 XL, and a new low-end Lumia 550. From what we have seen this far, these new devices will look gorgeous.

Lumia 950

These new devices not only will feature great hardware, but will also support Windows Hello through iris scanner. Also, the Lumia 950 and Lumia 950 XL will include support for Continuum for Windows 10 Mobile, which basically turns a traditional smartphone into a desktop PC.

With a new operating system on the horizon packing a bunch of new features and new great hardware, perhaps you may want to upgrade your old phone.

We'll show the steps you can follow to prepare your Windows Phone for sale and help you get some money back after buying your brand new Windows 10 Mobile handset. We'll help you make sure you're not giving away any personal information.

What you need to do to get your Windows Phone ready for sale

Backing up your data is your priority number one

No matter what device you use – phone, tablet, laptop, or desktop --, the first thing you want to do is to make sure you have a backup of all your data.

When you're using a phone, the backup is a little different, as you can't do a system image backup like you can on pretty much any computer running Windows. You can sync your pictures, videos, music, and a few other files to your PC, but for apps, settings, contacts, SMS, etc., you need to use the cloud backup options within the operating system to upload all that content to your Microsoft account.

Ideally, you'll want to back up your data, apps, and settings to your Microsoft account as it's a more secure and convenient environment.

Creating a full backup of your Windows Phone 8.1

Just like other platforms, the Windows Phone operating system doesn't include a main button to create a full backup of your handset. You need to go throughout the settings and make sure to back up all the necessary data.

If you're on Windows Phone 8.1, do the following: Go to Settings > Backup, tap on Apps + settings, and make sure to turn on Settings backup and App backup.

To backup your SMS and MMS to OneDrive do the following: Go to Settings > Backup, tap on Text messages, and turn on Text message backup.

Make sure to backup your pictures and videos to your OneDrive account: Go to Settings > Backup, tap on Photos + videos, and select the upload quality. (You may want to consider using the best quality possible.)

Creating a full backup of your Windows 10 Mobile

If you're running Windows 10 Mobile, do the following: Go to Settings > Update & security > Backup, and make sure "Back up content from participating apps" and "Back up settings like my Start screen layout, accounts, and passwords" options are turned On.

Once you configure the backup, your phone will backup automatically. If you want the backup to happen immediately, click the More options link, and click the Back up now button.

Make sure to backup your pictures and videos to your OneDrive account: Open OneDrive, tap the hamburger (menu) button on the top-left corner of the app, and tap the gear button on the top-right to access Settings. Then tap on Camera upload, and make sure to turn On the backup settings and you include your videos in the process as well.

To keep a copy of your texts to your OneDrive account do the following: Settings > System > Messaging and make sure to enable Text backup.

Reset your old Windows Phone to the default factory settings

If you have stopped using your phone because you bought a new handset, you probably already went through the backup and restore process. However, you still need to go through an important step.

Now you need to make sure that when you're selling your old phone, you're not giving away personal information. As such, it's the time to reset your handset.

There are two ways to reset your phone to the factory default settings. The first option is by using the reset feature within the phone and the second option is by using "Windows Device Recovery Tool" to erase everything and reinstall the operating system.

Note: It's important to note that at the time of the writing, Windows 10 Mobile continues in its preview stage, and currently doesn't offer a recovery feature through the Settings app. Because the new operating system is not publicly available yet, make sure you restore the original operating system instead of selling it with a pre-release version of Windows 10.

Reseting your handset running Windows Phone 8.1

If you're running Windows Phone 8.1, you can reset your phone by doing the following: Go to Settings > about, scroll down and tap the reset your phone option.

Then tap yes to confirm that resetting your phone will delete all your personal content, apps, games, pictures, music, and videos.

If you have an SD card, you'll have the option to erase its content as well.

Resetting your old phone by restoring the original image

In addition to the reset feature within Windows Phone 8.1, you can use the "Windows Device Recovery Tool" to restore the original operating system. It brings your phone to the factory default settings and erases your personal data, apps, games, pictures, music, and videos. As I mentioned above, if you're running Windows 10 Mobile Preview, you can use this method to roll back your phone to the factory defaults.

Below are all the steps you need to follow to accomplish this task:

  1. Download and install the latest version of the Windows Device Recovery Tool (opens in new tab) to your PC.
  2. Open the recovery tool and connect your Windows Phone using a USB cable. If your phone is not being detected, it could be that you're not using a data cable, also click My phone was not detected to force the tool to try detecting your phone.
  3. On the next screen, click your phone, and after several seconds, you'll see your handset information and the image available for download to go back to the original operating system. Click Reinstall software to continue.
  4. The software will warn you that you need to make a backup of all your data, but we have already done that, so you can now safely click Continue to complete the rollback.

The time to complete the process will depend on your phone, but it shouldn't take long. During the process, the recovery tool will download the original image from Microsoft's servers, and it will replace any existing version of the operating system.

Once the rollback completes, you'll see the "Operation successfully completed" message on the recovery tool, and now your phone is ready to go up for sale.

Now it's the time to sell your old Windows Phone

So far, we went through the steps and scenarios to make a backup of your device. You have also securely erased your personal data and reset your phone to the default factory settings.

Now, if you're not planning to keep your phone for testing purposes or just to have an additional phone in case your new phone stops working, then you can make some money by finding a new owner.

Just like you would do with any other product, one of the first things you want to do before putting your old Windows Phone up for sale is to figure out how much the same or similar phone is selling for. Of course, pricing will always vary depending on the condition and demand for that particular device.

If you don't know where to start, check out the market for the phone you want to sell -- visit the Microsoft Store online (opens in new tab), Amazon (opens in new tab), cellular network stores, and other online retailers, and see how much your old phone costs brand new (if it's still available).

Next, you want to visit eBay (opens in new tab) and http://Amazon.com (opens in new tab) to understand how much the same used phone costs. If they offer pictures of the device, see its condition to compare with your device.

Now, you have a pretty good idea on the price. The next step is to actually decide the price you want to sell your smartphone – take your time a decide wisely.

There are many services you can use to sell your old Windows Phone. You can try Swappa, Craigslist, eBay, Gazelle, Nextworth, and more. However, before you put up your item for sale, you may also want to consider to offer your used phone to someone you already know, as this can save you time and possible hassles.

It doesn't matter if you use Craigslist, eBay, or any other online service to sell your device. You want to make sure you describe the product as much as possible and emphasize on detailing its condition, and be as crystal clear.

Another important information you want to include in your description is to clarify if the phone you are selling is locked or unlocked. In addition, you want to mention in which cellular network (e.g., Verizon, AT&T, T-Mobile, etc.) you've used the phone and if it supports any other network. (Keep this in mind: One thing that people find very frustrating when buying a phone from a third party is not to be able to identify if the phone will work in their network. As such, if you're very clear, you will have a good chance of selling your old phone quickly.)

If you're not familiar with this information, you want to carefully see if you can get this info from online stores, cellular network stores, or even from the phone manufacturer's support web page.

Depending when you decide to sell your Windows Phone, make sure to note if the phone is upgradable to Windows 10 Mobile. Also, take good pictures of the handset and the accessories you are including (if any). Max out the amount of pictures you're allowed to post and be sure those pictures are very clear, showing the condition of the phone.

If you choose an online company such as eBay to sell your old smartphone, it's a good practice to offer fast and free shipping.

At the time of sending your old phone away, you want to ensure not to forget to remove the SIM card and battery (if applicable). If you don't know how to do this, check your phone user manual or check your phone's manufacturer support web page for more information.

Use good packaging to avoid damages and use a shipping method that offers tracking and signature require on arrival.

Removing your phone from your Microsoft account and disable Reset Protection

One additional step you want to do is to go to your Microsoft account (opens in new tab) and from the list of devices is to remove your phone. Simply click Remove phone, and on the next page check I'm ready to remove this device: Windows Phone and confirm the deletion. This is another important step as you are only allowed to install apps on up to 10 devices. Furthermore, you want to allow the person who buys your phone to be able to enable the "Find my phone" feature. (Thanks pmhgeneral for the tip!)

Finally, you want to double-check your handset doesn't have the Reset Protection enabled by going to your Microsoft account (opens in new tab). If you do, you will want to disable this feature so the new owner can reset the phone without problems. (Thanks micallan_17 for the tip!)

Wrapping things up

Although there are many users who will opt to keep their phone to continue testing the Windows 10 Mobile preview builds, new phones come and go very quickly. If you're already getting a new phone, you can always make a few extra bucks before the old device becomes obsolete.

Also note that we're not focusing on a single brand of phones in this guide, so you can use the steps mentioned above for other handsets as well.

During the Windows 10 devices event on October 6th, Microsoft is also expected to introduce the new Surface Pro 4. If you're a Surface Pro 3 owner and you're planning to get the new tablet, we go through the steps to sell your Surface Pro 3.

  • I have a crap load of Windows Phones dating from WP7.
  • this article = LOL whats the resell value of a WP phone? I tell you 0.00  
  • depending on the model, 1520's can be had for about $150-200, and 929/930s $100-175 unless in really poor shape... Now low end models that sell for $30-50 in the store new.... $10-30 if your lucky
  • That's because phones like the 1520, 1020, and 930 are still pretty damn awesome..
  • I went to where I always sell my phones and was flat out told he will not deal in trying to resell Windows Phone no matter what condition they are in - he said nobody will buy them from him
  • :)))) so much for the value...you get a WP, you end up with it forever. and we are speaking all over about marketshare? when no one wants to buy them, not even resale stores :)))
  • He's missing out on a market then. If you ask me he's stupid for turning down business. There's always avenues to sell something.
  • Lol❕❕❕❕❕❕
    ......
    How to sell your old WP?.... Step one, ask Cortana for the closest nursing home...
  • Nope, More than Zero. I sold my Old Lumia 520 with Great Price considering a Very Poor Battery Backup which last 5 hours.
  • So you gave somebody a bad deal?
  • i hope your right cause id love to buy a couple of 930s for very little money, hell that would be fantastic.
  • You = Lol. I've sold broken windows phones for more than $100. You're kind of an asshole, just saying.
  • Actually I just sold an HTC Windows Phone 8X in good working condition for almost $20. I know that isn't a significant amount of money, but considering it is a 3 years old phone that isn't supposed to get Windows 10 Mobile OS I was pretty happy with the offer. My old HTC One M8 for Windows is actually worth more, but unfortunately I had to send it back to Verizon as part of my upgrade. 
  • I sold my spare Lumia 635 new for $40. Good considering I bought it on a sale for $50/$60 during a short online promo.
  • Excellent write-up. I've never sold a device but either keep them for 3 years or they break. The kept ones are good spare cameras, music players or free phones for friends in need.
  • Yep, me too. Great handheld game machines for the kiddos too...
  • Same! Always a great feeling to help those in need, gave my friend my 8X.
  • Sound advice, but not sure that even the leaked renders have shown us new Microsoft phones that look gorgeous!!!!....opinion reserved until I hold one in my hand but still that's pushing it a bit ;) Subjective opinion I know.
  • :)) I was thinking this is new. Nobody yet called them gorgeous but ugly. And now with new leaks -a bit better
  • I've seen multiple sites calling them beautiful and good looking since the last leaks, and I agree. I think they are gorgeous. The first few renders weren't but the new ones, which are the only ones to actually be from Microsoft, are gorgeous in my opinion.
  • I think he meant gorgeous from a technical standpoint. The devices aren't the greatest beauties out there but I think they look decent, especially the 950 XL (I don't like the camera ring on the 950, at least on the renders).
  • I agree. "Decent" seems to be the new "gorgeous" as far as Lumia design is concerned. ;-)
  • mine wont back up on windows 10 latest build? it just hangs
  • I had/have this issue, as well. What works for me is to ensure the screen stays on the entire time (it takes about 10 - 15 minutes, usually). If the screen turns off, it will either hang indefinitely, stop, or close itself. Hope this helps!
  • thanks for this i will give it a go later when on a good WIFI network :)   as long as i dont loose the back up i have :)
  • This is how to prepare your old phone for sale :) Of old ones I have 710, dont think I going to sell it
  • Great advice. Unfortunately i lost my 920 in Mexico so cant sell that. I worked over the summer (I'm 16 btw) and earned enough to buy myself an unlocked 930, three weeks later it was stolen out of my bag at school. Sad day.  
  • I'm kinda glad it was stolen, no offense but at least windows phone is desirable among thieves. :P
  • I don't think the thief would have known that it is a windows phone while stealing it.  LOL.
  • I gave my girl a 822, when her Droid suddenly death. She have it ( and like it, but she's a teenager in the snap chat era and couldn't stand the lack of some apps and a crazy need for customize the look of the OS to match her colors likes including the keyboard ) for about 4 months until a couple of thieves stoles it. She didn't like soo much the replacement 521 ( lacks of front facing camera, NFC, LED flash, and better camera too. ) She when back to Android now :'(
  • We need SNAPCHAT.
  • Indeed we do..... But your comment is a long way from home. I'd direct you to the forums, but I don't know if people still spend time discussing it. Not heard much from the community about it.
  • Why?  What's so special about it??  Use Whatsapp
  • What's special about is is that 18 million females, and ⬆his guy, want it.....
    .......
    Females have mucho $$$$$$$$
  • Don't worry, it, along with any other Android application will soon be available on W10 Mobile.......
  • I wouldn't say soon, but highly possible...
  • Any idea how soon the phones will be available for purchase after the official announcement?
  • I suspect the earliest the 950 & 950XL will be available from cellular carriers is in late November.
  • Um.... on some that are on Windows 8.1 Update 2, don't you need to disable reset protection online? if not, on the next reset it'll ask you to log into your ms account.
  • Good point!
  • Now, this is a comment that belongs to this article.
  • I have an old Lumia 900 in perfect condition!  anyone interested?  Actually, I like keeping it around as a spare in case of emergency.  And it works great as a music player at parties.
  • You forgot to mention to turn off reset protection for those devices that support it
  • As far as I know and through the Microsoft documentation, reset protection gets turned off after you reset your phone. But you can always turn it off manually. That's the reason why I didn't include that step. Thanks,
  • It will get turned off but when the other user wants to set it up it wont as it will be locked. It happened to me when i did a reset on my lumia 830 :)
  • Post updated thanks,
  • Back up doesn't work for windows 8.1
  • Mine is gonna be given to my son. He is itching for a phone. Also need a UK pay as you go sim that "rolls over".
  • Step 1 Craigslist (no fees). Step 2 eBay (10-13% fee).
  • Step 2 swappa step 3 eBay
  • I hear you, but I would be hesitant to buy a phone on Craigslist. I have bought a few phones on eBay and had to return a couple. Got refunded with no problem. Not sure I would have been so lucky on Craigslist.
  • Selling is less risky even better, lol
  • Swappa and ebay, your safe for the most part besides the hassle, Craigslist you need to do your homework and fully test it right away (never mind checking ESN Pre-purchace) Buying one, questionable, Selling one, just be preped to be on point...the phone is XX, no less. Every meet for creigslist when I was selling stuff (about 20 tranactions so far), everyone accept for 1 tried to mooch me down when I showed up. And every time, I said, no and walked away. Be ready to walk... The only one who DIDN"T try to mooch me down was on something I was trying to get rid of and my price was really good (cheap because I wanted it gone)
  • I really hope that these phones are released on t-mobile day 1! I really want them but I am not switching carriers!  
  • Hopefully the phones are unlocked and have universal chips, then we can use them on any carrier.
  • Keep wishing.... T-mobile seems to be late to the party with windows phones.
  • Don't get your hopes up, lol...
  • Still got my 900 that I replaced the screen on but it's it for music. Always good to have an extra one even if it's not activated but it still dials 9-1-1 in case your actual phone goes dead for whatever reason.
  • I've already bought a Lumia 640 and I'll sell my Lumia 520. Thanks for the advices!
  • Might as well keep the 520 as a backup. Not worth much anyway.
