How to sell used phones online safely

You've got a phone worth about KSh 22,000, three people asking "is it still available", and one of them wants it delivered to Kayole with payment on delivery.

Say no to that one. For used phones specifically, the safe shape of a sale is: the buyer sees the IMEI before they commit, money confirmed in your own M-Pesa balance before the device leaves your hand, and a handover in a public place with cameras in daylight. Not a screenshot, not a rider, not the evening. Everything else in this article is detail around those three points, and the reason they matter more here than in any other kind of selling is that a phone is small, expensive, resaleable in ninety seconds, and identical in the dark to a broken one.

The good news is that the whole trade runs on a handful of checks that take four minutes and that most sellers skip.

Start with the IMEI, before you list

Dial *#06# on the phone. The IMEI appears on screen. It's the device's serial number and it's the single most useful thing in this business.

Three things to do with it:

1. Check it matches. The number on screen should match the one on the box, the one printed on the SIM tray or the back on some models, and the one in the settings under About. A mismatch means the phone has been opened and had a board swapped, or the box isn't the phone's box. Either way, walk away or price it as unknown.
2. Check it isn't blocked. Devices reported lost or stolen can be blocklisted, which means they will eventually stop working on networks, sometimes long after the sale. Ask your network operator what check they offer, and check whether your national telecoms regulator runs a device status lookup. This changes, and it has changed in Kenya more than once, so check what's current rather than what someone posted in a Facebook group two years ago.
3. Photograph it on screen before the device leaves your hands. This is your anti-swap evidence and I'll come back to it.

If you're buying stock to resell, do the IMEI check before money changes hands, in front of the person selling to you. Somebody who objects to you dialling six characters on a phone they claim is theirs is telling you something.

Proving condition, so the buyer doesn't have to trust you

Trust is expensive and evidence is cheap. Every listing should carry these, and almost none do.

Battery. On an iPhone, Settings, then Battery, then Battery Health, gives you a maximum capacity percentage. Screenshot it. Anything above 85% is genuinely fine, 80 to 85 is a conversation, below 80 should be priced as needing a battery. Most Android phones have no built-in figure at all, so say that plainly, give the phone's age and typical usage, and offer a charge test at handover instead of pretending you have a number you don't.

Screen, twice. One photo with the screen on, showing a plain white or light grey full-screen image, which is what reveals dead pixels, discolouration and burn-in. One photo with the screen off, held at an angle to a window, which is what reveals scratches. Sellers who only shoot the screen on are hiding scratches whether they mean to or not, and buyers know it.

A one-minute video. Phone in your hand, unbroken take: dial *#06# so the IMEI shows, open Settings and show the model and storage, open the camera and switch between lenses, play a sound through the speaker, plug in a charger so the charging icon appears. That video answers about fifteen chat messages and it makes you look like someone who has done this before.

The checklist, written out. Face ID or fingerprint working, all cameras, front and back, both speakers, microphone, charging port, wifi, Bluetooth, SIM tray and whether it's dual SIM, network bands, whether it's carrier-locked, and any repairs done with what parts.

Say what's wrong. A named scratch on the top left corner, a slightly loose volume button, a replaced screen that isn't original. Every disclosed flaw is a flaw that can never be a dispute. Every hidden one is a refund plus a public complaint.

A flaw in the listing costs you a few hundred shillings on the price. The same flaw discovered at handover costs you the whole sale and your reputation in that group.

Sign out before you reset, not after

This is the order of operations that ends more used-phone sales in an argument than anything else.

On an iPhone: sign out of iCloud first, in Settings, then erase all content and settings. If you factory reset a phone while the Apple account is still signed in, the activation lock stays on. The phone reboots into a setup screen asking for a password neither of you has, and it is a brick until the original owner signs in remotely. Neither party finds out until the buyer tries to set it up, usually after they've paid and gone home.

On Android: remove the Google account from Settings, then reset. Same problem, same result.

Do the sign-out and the reset in front of the buyer, at the handover, not the night before. It takes about six minutes on the mall wifi and it turns "trust me, it's clean" into something they watched happen. It also means you're not walking around with a wiped phone if the meeting falls through.

And take the SIM out. Yours, obviously, but check the tray again after the reset, because everyone forgets this once.

Meeting safely

Kenya-specific, and it applies in most cities.

• Daylight, always. Not 7pm, not "after work". If they can only do evenings, do the weekend.
• A mall, a bank forecourt, or a petrol station with cameras. Somewhere with a guard and CCTV. Inside, not the car park.
• Bring someone. A second person changes the dynamic entirely and costs you nothing.
• Never go to a residential address, and never let the deal move somewhere else at the last minute. "Come to my place, I'm at home" and "let's step outside, the light is better" are both the same request.
• Don't hand the phone over until the money is confirmed. Not confirmed in a message. Confirmed in your balance.
• Let them test it as long as they like, in front of you, in the open. A buyer who wants to take it out of sight to test it is not testing it.

If a buyer is being difficult about all of this, that's information. Real buyers are usually relieved that you're being careful, because they're worried about being scammed too.

The M-Pesa message is not the money

The most common scam against Kenyan sellers is a message that looks exactly like an M-Pesa confirmation. Correct sender name, correct format, correct amount, correct-looking transaction code. Some of them are forwarded, some are sent from a spoofed sender, some are just a screenshot.

Do not read the message. Check your balance.

Open the M-Pesa app or dial your balance check yourself, on your own phone, and confirm the money has actually landed and that the amount is right. If you use a till, check the till statement rather than the SMS. Do this while the buyer is standing there. It takes twenty seconds and it costs you nothing socially, because you can say "just checking, one second" and every Kenyan seller understands why.

The same principle applies to bank transfers, which are the other rail people will offer for a larger device: a screenshot proves a screen existed, nothing more. There's a longer treatment of the whole problem in how to take payment as a small seller, and the specific business of matching incoming payments to orders is in proving you are a real seller, which is the flip side of this and worth reading if buyers keep ghosting you.

Why cash on delivery is the wrong rail for this specifically

COD is normal in Kenya and it works well for a lot of goods. For used electronics it's genuinely dangerous, and for four distinct reasons.

The swap. The buyer inspects the phone at the door, hands back a device that looks the same, and refuses the order. The rider brings you back a phone. It is not your phone. It's a broken unit, or a display dummy, or a different phone entirely, and you find out when you check the IMEI that evening. You have no proof of what went out unless you photographed the IMEI on screen before dispatch, which is exactly why you photograph the IMEI on screen before dispatch.

The value. You are asking a boda rider to carry KSh 22,000 of easily-resold goods and then carry KSh 22,000 of cash back. That is a real risk to a real person, and most riders are not insured for anything near that.

The refusal. On COD, a buyer can change their mind for free. On a phone, where the buyer has spent three days comparing prices, refusals are common, and you've paid the rider both ways for nothing.

The reconciliation. COD money reaches you days later, in a lump, and matching it to orders is its own weekly chore. That's true of all COD and it's covered in cash on delivery for small sellers and in rider handovers and cash reconciliation.

What to do instead, in order of preference:

1. Meet in person, in a mall, in daylight, money confirmed first.
2. Full payment before dispatch for out-of-town buyers, with the IMEI photographed, the box sealed with tape you've signed across, and a tracked courier. Send the buyer the IMEI photo and the tracking number at the same moment.
3. A deposit that covers the round trip, if you're going to allow inspection on delivery at all. Say clearly that the deposit isn't refunded if the device comes back and the IMEI matches what went out.

Never do full COD on a device above your own pain threshold. Whatever number makes your stomach turn, that's the ceiling.

Pricing used devices without guessing

Three inputs, checked the week you list:

• What the same model, storage and condition is actually listed at right now on the marketplaces your buyers use. Not what it cost new, and not what you paid.
• The condition discount. A cracked back, a replaced screen, a battery under 85%, or no box each knocks a real amount off. Be honest with yourself about it, because the buyer will be.
• What it costs you to make it sellable. A battery replacement, a screen, a deep clean, a charging port.

Then a fourth thing that nobody counts: how long it will sit. Phones lose value continuously, and a device priced 8% above market that takes six weeks to sell has cost you more than one priced at market that goes in four days. Speed is worth money in this trade.

Include the accessories you actually have, and say which are original. "Original box, original cable, third-party charger" is a sentence that earns trust and adds a few hundred shillings.

Worked example: Brian, Nairobi

Brian buys used iPhones, refurbishes what needs it, and sells 10 to 14 a month. He sources from walk-in sellers and from the shops around Luthuli Avenue.

A recent one: bought an iPhone 12, 128GB, at KSh 24,000, with a battery at 78% and a scuffed frame. Battery replacement KSh 3,800. A protective case and a screen protector to go with it, KSh 700. Total in at KSh 28,500. Listed at KSh 34,500 with photos of the new battery health reading at 100%, the screen on and off, the IMEI, and a one-minute video. Sold in nine days at KSh 33,000 after a negotiation, so about KSh 4,500 on the deal.

His rules, learned expensively: every device gets its IMEI photographed on screen before it leaves the shop, every handover is at a mall between 10am and 4pm, every payment is confirmed in the M-Pesa app rather than by SMS, and he offers a 7-day return for hidden faults with no return for anything cosmetic that was in the photos. The 7-day return costs him roughly one device in twenty and it's the reason half his sales come from referrals.

He lost KSh 31,000 once, in his first year, to a delivery where the buyer inspected the phone at the gate and sent a different one back with the rider. He'd taken no IMEI photo. There was nothing to argue with.

The honest limitation

Nothing in a shop platform makes a used-phone deal safe. Sailo holds your listing, your photos, your prices and your orders. It has no escrow, it can't verify a device, it can't check an IMEI, and it can't hold a buyer's money until they confirm the phone is genuine. Any platform claiming otherwise on this category is worth reading very carefully.

It also has no M-Pesa rail. The complete list of payment rails is card, WhatsApp, Telegram, Instagram, email, phone, bank transfer and cash on delivery. What you can do is put your till number and your registered business name into the bank transfer instructions, which is a real advantage in Kenya because the buyer sees the registered name before they confirm, and that's a trust signal a bare account number can't match. But the money moves through Safaricom and your own phone, not through Sailo, and Sailo cannot tell you it arrived. You check that yourself, every time, before the device leaves your hand.

Card payments, if you want them, cost 3% of the goods on the free plan and 1% on Business. There's a further wrinkle worth checking before you plan around them at all: Sailo's card rail runs on Stripe and only Stripe, with no Paystack support, and Stripe isn't available to sellers in every country. Check whether you can actually open a Stripe account where you are before you upgrade, because if you can't, no plan will produce a card button.

What to do next

Take the device you're selling now and do the four-minute pass: dial *#06# and photograph the IMEI, check it against the box, screenshot the battery figure if the phone gives you one, and shoot the screen on and off.

Then write your handover rule into your listing in one line, so it's a policy rather than an awkward negotiation: payment confirmed in my M-Pesa before handover, meetings at [your mall] between 10am and 4pm. Buyers who don't like it were going to be a problem, and the ones who message you next are the ones worth serving. If you're already fielding a lot of enquiries that go nowhere, dealing with fake orders and time wasters covers how to filter them before they cost you a Saturday.
