How to Wipe Your Android or iPhone Before Selling (Kenya Guide)

Selling a used phone in Kenya is one of the easiest ways to free up cash before an upgrade. But before you hand your device to a buyer in Nairobi CBD, post it on a marketplace, or drop it off at a shop in Mombasa, there is one step you must never skip: wiping it properly.

A quick "Delete All" or pulling out the SIM card is not enough. Your phone holds your M-Pesa PIN history, banking apps, WhatsApp chats, photos, saved passwords and your Google or Apple account. If you sell it without a proper wipe, a dishonest buyer could access your money or your private life. Worse, if you forget to remove your account, the new owner may be locked out and demand a refund.

This guide walks you through exactly how to back up and securely wipe both Android phones and iPhones before selling, using steps that work for any phone sold in Kenya, from a Tecno Spark to an iPhone 15.

Why a Factory Reset Alone Is Not Enough

Many Kenyans assume that tapping "Factory Reset" deletes everything. It mostly does, but there are two big traps:

  1. Account locks (FRP and Activation Lock). If you reset an Android phone without first removing your Google account, Factory Reset Protection (FRP) kicks in. The next person must enter your old Google details to use the phone, making it almost worthless. On iPhone, the same thing happens with Activation Lock if Find My iPhone is still on.
  2. Recoverable data. On older Android phones without encryption, deleted files can sometimes be recovered with software. Modern phones encrypt storage by default, so a reset is usually safe, but you should still follow the full process below.

The golden rule: sign out and turn off Find My BEFORE you reset. Do it in the wrong order and you will have to factory reset twice.

Step 1: Back Up Everything You Want to Keep

Once you wipe the phone, your data is gone. Save what matters first.

Photos and videos

  • Android: Open Google Photos, tap your profile picture, and confirm "Backup complete." A free Google account gives you 15GB shared across Gmail, Drive and Photos.
  • iPhone: Settings > [Your Name] > iCloud > Photos, and turn on sync. The free iCloud tier is only 5GB, so you may need to copy photos to a laptop instead.

Contacts

  • Make sure contacts are synced to your Google or iCloud account, not just saved on the SIM or phone storage. On Android: Settings > Google > Backup. On iPhone: Settings > [Your Name] > iCloud > Contacts (on).

WhatsApp (almost everyone in Kenya uses it)

  • Open WhatsApp > Settings > Chats > Chat backup, and tap "Back up now." On Android this goes to Google Drive; on iPhone to iCloud. You will restore it on your new phone using the same number.

M-Pesa and banking apps

  • You do not back up these. Just make sure you remember your PINs and that the apps are linked to your SIM and ID, not the device. After the wipe you will reinstall them on your new phone.

Files and documents

  • Copy anything important (KRA PIN certificates, payslips, school documents) to Google Drive, email it to yourself, or move it to a laptop or flash disk.

Step 2: Sign Out of All Your Accounts

This is the step most people forget. Sign out of:

  • WhatsApp is tied to your number, so you do not need to "log out," but do the backup above first.
  • Email apps (Gmail, Outlook), social apps (Facebook, Instagram, TikTok, X).
  • M-Pesa app, bank apps (Equity, KCB, Co-op, Absa), and betting or wallet apps. Log out and, where possible, remove the device from the app's trusted devices.
  • Streaming and shopping (Netflix, Showmax, Jumia) so the buyer cannot use your subscription or saved cards.

Step 3: How to Wipe an Android Phone

Most phones in Kenya run Android (Samsung, Tecno, Infinix, Xiaomi, Oppo, itel). The menus differ slightly by brand, but the path is similar.

3a. Remove your Google account

Go to Settings > Accounts (or Passwords & accounts), tap your Google account, and choose Remove account. This disables Factory Reset Protection so the buyer can set up the phone freely.

3b. Remove screen lock and SIM

Turn off any PIN, pattern or fingerprint lock under Settings > Security. Then physically remove your SIM card and any microSD memory card.

3c. Factory reset

  • On most phones: Settings > System > Reset options > Erase all data (factory reset).
  • On Samsung: Settings > General management > Reset > Factory data reset.
  • On Tecno, Infinix and itel: Settings > System > Reset > Erase all data.

Confirm with your PIN. The phone will erase everything and restart to the welcome screen. This can take a few minutes.

3d. For older phones, encrypt first

If your phone is several years old and you are worried about data recovery, you can fill the storage with junk before resetting: copy large video files until the phone is nearly full, then factory reset again. On encrypted modern phones this is unnecessary.

When the phone reboots to the "Welcome / Choose language" screen with no account prompt, it is ready to sell.

Step 4: How to Wipe an iPhone or iPad

iPhones are popular for resale in Kenya because they hold value well. The process is built in and very secure.

4a. Turn off Find My iPhone

Go to Settings > [Your Name] > Find My > Find My iPhone and toggle it off. Enter your Apple ID password. This removes Activation Lock. If you skip this, the buyer cannot use the phone at all.

4b. Sign out of your Apple ID

Still in Settings > [Your Name], scroll to the bottom and tap Sign Out. Enter your Apple ID password.

4c. Erase the iPhone

Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Enter your passcode and Apple ID password to confirm. The iPhone wipes itself and restarts to the "Hello" setup screen.

4d. Remove your SIM

Eject the physical SIM tray with the pin tool (or a paperclip). If you use an eSIM with Safaricom or Airtel, the erase process handles it, but confirm there is no eSIM profile left.

When it shows the "Hello" screen and does not ask for an Apple ID, the iPhone is clean and safe to sell.

Step 5: Confirm It Is Truly Wiped

Before you meet a buyer:

  • Power the phone on and check it boots to the fresh setup screen with no account prompt.
  • Confirm there is no SIM or memory card inside.
  • Have your original box, receipt, or charger ready, as these raise resale value and build buyer trust.
  • Dial *#06# to note the IMEI. A genuine, unblocked IMEI reassures buyers, and the buyer can SMS the IMEI to 1555 to check it is not flagged by the Communications Authority of Kenya (CA).

A Quick Word on Safety When Meeting Buyers

A clean phone protects your data, but you also need to protect yourself during the sale. Meet in a busy, well-lit place such as a mall or bank entrance, confirm M-Pesa payment has actually reflected (check your own SMS, never trust a screenshot), and bring someone along if you can.

Frequently Asked Questions

Does a factory reset remove my M-Pesa? Yes, it removes the M-Pesa app and any saved data from the phone. Your actual M-Pesa account stays with your SIM and ID, so you simply reinstall the app on your new phone. Still, log out before resetting and remove your SIM.

Can the buyer recover my photos after I wipe the phone? On modern encrypted Android phones and all iPhones, a proper factory reset makes recovery practically impossible. For very old phones, fill the storage with junk files and reset twice to be safe.

What happens if I forget to remove my Google or Apple account? The phone will lock the buyer out (FRP on Android, Activation Lock on iPhone) and demand your account details. You will likely have to take it back and sign in remotely to release it, so always sign out before selling.

Do I need to remove my SIM card before selling? Yes. Your SIM holds your number, M-Pesa line and sometimes contacts. Never sell a phone with your SIM inside.

Should I wipe the phone myself or let the shop do it? Always wipe it yourself before handing it over. Never give anyone your unlocked phone to "reset for you," as they could copy your data or access your money first.
