Why You Should Sell Your Mobile Sooner Rather than Later

If you’re on the fence as to whether or not you should keep your old phone around, we have a few reasons that might change your mind.

If you’re on the fence as to whether or not you should keep your old mobile around, we have a few reasons that might change your mind.

The biggest reason? Value.

Much like laptops, cars, or anything else with a hefty price tag, your mobile is bleeding value by the day.

What’s worth a nice price now could be essentially worthless in a few months.

Unless you have a major reason to keep hold of your old mobile, you’re probably better off getting rid of it while the price is good.

For many models, this is a window that lasts about two years.

After that, unless you have a rare variant or a super popular device, you’re looking at a fraction of what it would sell for today.

Next up is risk.

Condition is everything when it comes to fetching a good price for your gently used mobile.

Every day that your mobile sits in the closet, in a drawer in the kitchen, or hangs out in your purse is another day that the kids might decide to play £400 frisbee, a leak could give your mobile impromptu swimming lessons, or you just might drop the thing and shatter the screen.

Even small dings to the case or slight scuffs are slowly shaving money off the top of your potential pile of bills.

Finding the Timing Sweet Spot

So we know that sooner is better than later, but are there any major trends you can keep an eye on to know just when later is?

The biggest thing to keep in mind is release dates for upgrades to your current mobile.

If you’re an Apple fan, this means that September is the time to cut your mobile loose or lose value.

Android and Windows mobile users won’t have a firm date, but if you keep an eye on our mobile reviews, you’ll probably have enough notice of a new release to keep a fair portion of your resale value.

From the moment the next model is announced until release day, you can research your options and still make a considerable amount.

However, once the latest and greatest drops, you can kiss a portion of your profits goodbye.

Trade-in sites are one caveat this though. We'll cover those in greater detail in a moment.

Where to Sell Your Used Cell Mobile

So now that we’ve covered the why’s and when’s of reselling your used mobile, we can get into the finer points of milking the sale for the maximum profit.

Sometimes, where you sell your old phone or tablet can impact your earnings just as much as the condition of the mobile or timing.

In general, you can sort selling options into one of three categories:

1. Retail Trade-In Sites (£)

Major high street retailers and network stores will buy back used mobiles in decent condition.

You bring in your mobile, any accessories you might have, and (sometimes) proof of purchase. They’ll do a quick appraisal and offer you store credit in most cases.

Popular options include:






Carrier Stores (Including Three, EE, BT Mobile, and O2)

These options are certainly the easiest and fastest at your disposal.

Unfortunately, this convenience comes at a price. You’re likely to earn half what you might make going with an online auction or classified site and slightly less than many popular online trade in sites.

But if you need the money in a pinch or you’re itching to upgrade, instant store credit can go a long way.

2. Online Trade-In Sites (££)

These sites typically offer a few different guidelines for self-appraising your mobiel.

After listing your mobile model, condition, and answering a few questions, the site will give you a quote and send you a prepaid shipping container.

You drop your mobile in the post and, if they agree with your appraisal, the check is on the way.

Where things get tricky is if they don’t agree with your appraisal.

Always be sure to read the fine print before posting your mobile.

While many options will allow you to accept a lower offer or return your mobile for free, choosing a reputable site or service can help eliminate any risk or concerns.

Sites that buy used mobiles won’t quite hit the prices you’ll find selling your mobile yourself, but they’ll often beat their retail competitors by enough to make the wait worth it.

Popular options include:


Carrier Websites (Including Three, EE, BT Mobile, and O2)

3. Online Sales Sites (£££)

Online sales sites differ from trade in sites in that you’re making deals with private parties instead of receiving offers.

Whether you’re posting an auction on eBay or listing your phone on Craigslist, these sites require you to put in a little more effort.

However, you’ll get a better price most times as well.

Popular options include:



When using these sites, you’re responsible for shipping your mobile or arranging pick-up.

Payment methods vary from cash or cheque to PayPal.

Most major sites offer forms of buyer and seller protection taking the worry and risk out of the sales process.

These sites all offer excellent exposure -- often giving your ad a worldwide presence -- to ensure your ad is seen. They also offer some of the best chances of getting top prices for your device.

Of course, with that comes plenty of competition.

But don’t worry...

We’re about to explain how to make your ad stand out and fetch the best price for your mobile.

5 Tips to Help You Dominate the Sales Sites

While many of these tips also apply to trade ins, you’ll find them particularly effective on auction and private sales sites.

With so many ads out there and buyers looking to get the best deals possible, each of these tips will add a little something extra to your ad to help you rise above the rest of the sellers.

1. Keep Your Mobile in Good Condition and Be Honest About the Flaws

Even if you bought a case at the store, went through screen protectors like candy, and took great care of your mobile, there’s a good chance there are still a few scratches or the odd little quirk.

It still works great, but it’s not mint.

When creating your listing, be sure to outline how you took care of your mobile.

Provide pictures from as many angles as possible. Take pictures with the screen on and at maximum brightness. If it has a removable cover, pop that off and take a picture of the battery bay.

Snap a pic of everything you can think of... and a few more for safe measure.

This includes the little chip in the bezel that happened before you bought your case or that slight haze from spending a year in the pocket of your jeans with your car keys.

Being honest about the small flaws will create trust and inspire confidence for bidders.

2. Save Your Original Boxes and Accessories

The closer you can get your phone to the retail package, the more money you’ll make reselling down the road.

From the little key used to pop out your SIM card to the manuals and crappy earbuds that your phone shipped with, each of these items is a piece of the puzzle.

Keeping track of them all not only makes buyers happy but shows you cared about your device. Take pictures of everything and be sure to list it in your product descriptions.

If you don’t have the original chargers or cables, picking up a cheap replacement from Amazon can more than pay for the replacement cost in your final sales price.

Just be sure to mention they are third-party accessories in the listing.

3. Unlock Your Phone and Expand Your Market

Locked mobiles will only work with a specific network.

While this might not be a problem for you, it immediately limits potential buyers unless they know how to unlock the mobile.

Regulations in many countries now require networks to unlock mobiles upon request as long as you have met the conditions of your contract.

Checking your network’s website or calling customer service is the quickest way to find out your official options.

Depending on your network, you might run into limitations on the number of devices you can unlock at once or find that they ask for a small fee.

You should have no problem recouping the cost of unlocking in the sale price of your phone.

If you don’t have any luck with your network, you can check local mobile shops or even your online classifieds.

Unlocking services are increasingly common as the second-hand mobile market continues to expand.

Just be sure to research any option you find thoroughly before spending any money.

4. Sweeten the Deal by Including Your Accessories

If you have any of the official accessories for your device, such as dashboard mounts, desk charging docks, or flip cases, consider including them with your listing.

Depending on the design, they might be collecting dust as well.

By including them with your listing, you’re offering convenience to buyers.

Instead of having to order all their own accessories, pay additional shipping, and wait for them to arrive, they can look forward to one quick and easy bundle.

This can add quite a premium to your listing and help it stand out from other listings.

5. Hold Firm on Your Price

If you’re posting on classified sites, such as Craigslist, you’ll inevitably find yourself inundated with low-ball offers looking to whittle you down to nothing for your mobile.

If you’ve done your research, you know what your phone is worth.

Don’t give in.

Even if you don’t eventually sell at the price you want, you can always go the trade in route for guaranteed cash or credit.

Adding a little padding to your price will allow for a bit of haggling if needed, but stick to your ground and know your absolute minimum.

You’ve Sold Your Mobile… Now What?

After you’ve raked in the chips for your mobile, you’re still not quite done.

There are a few steps that you should ALWAYS perform prior to posting your mobile on its merry way.

The first is to give it a thorough cleaning and to double check that everything mentioned in your listing is included in your box.

No one wants a smudgy mobile or weird mystery crumbs lurking in the battery slot. More importantly, presenting a pristine mobile reduces the chances of the seller disputing the condition of your mobile.

The second step is to document your mobile’s ESN or IMEI.

This is often found on the rear of the device, on the retail box label or inside the battery bay.

Take a picture and keep it somewhere safe. This number is unique to your mobile. Should you encounter any issues with scammers or disputes, this information is one of the only ways to verify the device.

Finally, clear any personal data off your mobile, remove your SIM card and any additional storage cards you might have installed.

While the manual might make it sound like this is as simple as a factory reset, clever users can still harvest a variety of information from your mobile even after a basic formatting.

Android users can use the free Avast Anti-Theft App.

You can initiate a full wipe of an iOS device using your iCloud account.

You should also be sure to remove your mobile from your Apple accounts as well to ensure that any access to iTunes data and purchases is prevented when the buyer connects your mobile to activate it.

So there you have it!

All that’s left is to break out the cleaning wipes, shine up that old mobile or tablet, and start figuring out how to spend your new pile of cash!

Common Questions

Is it better to sell privately or sell my mobile to a store or service?

This all depends on how much work you want to put into selling your mobile and what type of protections you're looking for in the sales process.

Selling your mobile to a store or service often means you'll receive a bit less than if you'd have sold the mobile to a private party.

But you don't need to worry about haggling, meeting up in a shady location, or someone contesting the sale.

It's the easier, faster way to go -- but you earn less.

On the other hand, selling to a private party through online classifieds or a similar arrangement might allow you to pocket more money.

But it comes with risks, including having to deal with random people from the Internet, contested payments, dealing with low-ball offers and spam, and waiting for a buyer who is serious.


Selling your used mobile is a simple way to add some funds to your financial situation and keep a useful mobile from gathering dust.

Keep the following in mind to ensure you get maximum value for your old mobile:


Try to avoid selling your mobile right when a new model drops


Network and retail buyback programs are easy but offer less money than other methods


Sites that buy used mobiles or allow you to sell your used mobile are often a good balance of risk and rewards


Using an online classified is likely to net you the most for your used mobile, but it's the most work and comes with increased risks


Take the time to clean up your mobile before selling -- no one wants a dirty mobile


If selling online, take pictures of everything


Unlocked mobiles sell better than locked ones


Sweeten the deal by including accessories


Always factory reset your mobile before selling it
