Having your phone stolen can be more serious than losing the device itself. A smartphone may contain your mobile-money account, banking apps, email, WhatsApp conversations, photographs, contacts, social-media accounts and other private information.

If your phone has been stolen in Kenya, act quickly. Blocking the SIM card, securing the device remotely and protecting your financial and online accounts can significantly reduce the risk of someone accessing your information or using your number.

This guide explains how to block a stolen phone in Kenya, how to use the phone’s IMEI number, how to secure a Safaricom or Airtel SIM, and what Android and iPhone users should do immediately after theft.

Important: Do not attempt to physically confront or track down a suspected thief yourself. If a tracking service shows the phone at an unfamiliar location, contact the police instead.

What to Do Immediately After Your Phone Is Stolen

Before worrying about recovering the handset, protect your accounts and personal information.

Follow these steps as soon as possible:

1. Lock or mark the phone as lost remotely.
2. Contact your mobile network provider and report the SIM as lost or stolen.
3. Request a replacement SIM if necessary.
4. Protect your mobile-money account.
5. Change important passwords if you believe the thief could access them.
6. Report the theft to the police.
7. Keep your phone’s IMEI and purchase information for identification and reporting.

The order can vary depending on your circumstances. If you believe someone knows your phone’s PIN or the phone was unlocked when stolen, prioritise securing your accounts immediately.

How to Block a Stolen Phone Using Its IMEI

The IMEI, or International Mobile Equipment Identity, is a unique number used to identify a mobile device. Most mobile phones have a 15-digit IMEI number.

The Communications Authority of Kenya (CA) provides an IMEI verification service through which consumers can check whether an IMEI is valid. The Authority says users can dial *#06# on a phone to display its IMEI and can also verify a 15-digit IMEI by sending it to 1555.

However, you should understand an important distinction:

You do not personally block a stolen phone by simply entering the IMEI somewhere online.

The IMEI is the device identifier that a mobile operator can use when dealing with device blocking. Google also notes that a mobile service provider can use the IMEI to disable an Android device.

What to do

If your phone has been stolen:

1. Find your phone’s IMEI number.
2. Contact your mobile network provider.
3. Report the phone as stolen.
4. Provide the IMEI if requested.
5. Follow the operator’s instructions regarding device and SIM blocking.
6. Keep any reference number you receive.

If you have difficulty resolving the issue with your provider, you can escalate an unresolved consumer complaint to the Communications Authority of Kenya after following the provider’s complaints process.

How to Find Your IMEI After Losing Your Phone

You do not necessarily need the physical phone to find its IMEI.

Android phones

Google’s Find Hub can display the IMEI associated with a supported Android device.

You can access Find Hub through Google’s lost-device service and select the device you want to manage. Google says the IMEI can be found under the device’s settings in Find Hub.

You may also find the IMEI on:

• The original phone box
• Your purchase receipt
• A device warranty document
• Your manufacturer’s account or device records
• Previous records where you wrote down the IMEI

iPhone

For an iPhone, check your Apple Account/device information, original packaging, purchase documentation or other records associated with the device.

Apple says law enforcement may request the serial number when you report a stolen iPhone.

Dual-SIM phones

Some phones have two IMEI numbers.

If your device had two IMEIs, keep both numbers and provide them to your network provider when reporting the theft.

How to Lock a Stolen Android Phone Remotely

Android users can use Google Find Hub to locate, secure or erase a lost device.

Google says a supported Android phone can be managed remotely when it has power, is connected to mobile data or Wi-Fi, is signed into a Google Account, has Find Hub enabled and is visible on Google Play.

Step-by-step

1. Use another phone, tablet or computer.
2. Open Google’s Find Hub service.
3. Sign in using the Google Account associated with the stolen phone.
4. Select the missing phone.
5. Check its available location information.
6. Select Mark as lost to lock the device.
7. Follow the instructions to display a message or contact information on the lock screen if appropriate.

Google says Find Hub can also provide the device’s last known location when its current location cannot be found.

Should you erase the Android phone?

If you believe you cannot recover the phone and your personal information is at risk, you can consider remotely erasing it.

But understand the consequence:

After an Android device is erased, its location will no longer be available through Find Hub. Google also warns that remote erasure permanently deletes data from the device, although it may not delete information stored on an SD card.

For that reason, consider locking and locating the phone first before choosing the erase option.

How to Lock a Stolen iPhone

If your iPhone has been stolen, Apple recommends marking it as lost as quickly as possible.

You can use the Find My app on another Apple device or visit Apple’s Find Devices service through iCloud.

Step-by-step

1. Go to Apple’s Find Devices service.
2. Sign in with your Apple Account.
3. Select the stolen iPhone.
4. Choose Mark as Lost.
5. Follow the instructions.

When an iPhone is marked as lost, it is locked with the device passcode. Apple says payment cards and passes used with Apple Pay are also suspended when the device is placed in Lost Mode.

If you later determine that the phone cannot be recovered, you can remotely erase it.

Do not remove a stolen iPhone from Find My

This is extremely important.

Apple warns that removing a stolen iPhone from Find My removes Activation Lock, making it easier for a thief to erase and resell the device. Even after remotely erasing the phone, Apple recommends keeping it in Find My.

How to Block a Stolen Safaricom SIM Card

If your stolen phone contains your Safaricom SIM, act quickly.

A stolen SIM can potentially expose you to account takeover, fraudulent transactions and attempts to access services connected to your mobile number.

Safaricom’s prepaid terms specifically address lost or stolen SIM cards and provide for SIM replacement, with applicable replacement conditions or fees.

What you should do

Contact Safaricom through its official customer-care channels and report the SIM as lost or stolen.

You should then ask about:

• Blocking the lost SIM
• Replacing the SIM
• Protecting your M-PESA account
• Securing other services linked to the number

When replacing a SIM, you may be required to go through identity verification.

Do not give your M-PESA PIN, passwords or verification codes to someone claiming to be helping you recover the phone.

How to Block a Stolen Airtel SIM in Kenya

Airtel Kenya also provides procedures for customers whose SIM cards are lost or stolen.

Airtel’s published information says customers can report a lost or stolen phone through its customer-care channels. Its listed contact number for this service is +254 733 100 100.

Airtel’s prepaid terms also provide for replacement of a lost or stolen SIM at the customer’s request, subject to the operator’s requirements.

If you use Airtel Money, tell customer care that the stolen phone contained your mobile-money-enabled SIM so they can advise you on securing the account.

Protect Your M-PESA Account After Phone Theft

This should be one of your highest priorities if your stolen phone had a Safaricom line.

Do not assume that having a SIM PIN or phone lock automatically makes your M-PESA account completely safe.

Contact your mobile operator immediately and report the theft.

Also consider:

• Blocking the stolen SIM
• Getting a replacement SIM
• Checking recent transactions
• Reporting transactions you do not recognise
• Changing relevant passwords
• Securing your email account
• Monitoring your bank accounts and other financial services

Kenya’s Communications Authority reported in August 2026 that telecommunications and digital financial services were among the largest categories of consumer complaints, with concerns including SIM replacement fraud, identity theft and unauthorised access to consumer accounts.

That makes fast action particularly important after losing a phone that is connected to financial services.

Secure Your Gmail and Google Account

Your phone may contain a logged-in Google Account.

If you have lost control of the device, review your Google Account security from another device.

Pay particular attention to:

• Recent sign-ins
• Devices connected to your account
• Recovery phone numbers
• Recovery email addresses
• Two-step verification
• Saved passwords
• Suspicious activity

If you believe someone knows your Google password, change it immediately.

For Android users, Google also recommends having account and device recovery arrangements in place before a phone is lost.

Secure Your Apple Account

If an iPhone has been stolen, check your Apple Account from another trusted device.

Apple recommends reviewing account information, associated devices, phone numbers and recovery methods after a theft. If you see changes you did not make, update your information and change your Apple Account password.

Apple also warns users to be careful about phishing messages and fake support calls following an iPhone theft.

A particularly dangerous scam is a message claiming:

“Your iPhone has been found. Click here to see its location.”

Never enter your Apple Account password or verification code into an unfamiliar website.

What About WhatsApp?

If your stolen phone was logged into WhatsApp, protect your phone number and account as quickly as possible.

Once you regain control of your mobile number through your network provider, sign into WhatsApp on your replacement phone using the same number.

Also review:

• Linked devices
• Two-step verification
• Recovery email
• Suspicious activity

Do not share WhatsApp verification codes with anyone.

Report the Stolen Phone to the Police

You should also report the theft to the police, particularly if the device was stolen during a robbery or other crime.

Keep as much information as possible, including:

• Phone make and model
• Colour
• IMEI number
• Serial number
• Phone number
• Purchase receipt, if available
• Date and approximate location of theft
• Any identifying marks
• Tracking information, if available

If a tracking service shows the phone at a location you do not recognise, do not go there yourself.

Apple specifically advises users not to attempt to recover a stolen device themselves when its location appears at an unfamiliar place. Instead, contact law enforcement.

Can an IMEI Block Make a Stolen Phone Completely Useless?

Not necessarily.

IMEI blocking and remote device locking are different layers of protection.

An IMEI is used to identify the mobile device, while Android’s Find Hub and Apple’s Find My provide device-specific security and recovery features.

You should therefore use multiple protections:

SIM protection + IMEI reporting + remote device lock + account security + police report.

Do not rely on only one of them.

What If the Thief Removes the SIM Card?

Removing the SIM does not automatically remove all of the phone’s security protections.

A smartphone may still be protected by its screen lock and manufacturer account.

For example, an Android device can be managed through Find Hub when its required conditions are met, while an iPhone can remain associated with Find My and Activation Lock.

This is one reason you should secure the device remotely as soon as possible.

What If the Phone Is Switched Off?

Don’t panic.

A switched-off phone may not immediately provide a current location.

Depending on the device and settings, however, you may still see a last known location or be able to issue security commands that take effect when the phone reconnects.

Google says Find Hub can show a last known location when a current location cannot be found.

Apple similarly says Lost Mode becomes active when the device is turned on and connected to Wi-Fi or cellular service.

How to Prevent Problems If Your Phone Is Stolen Again

The best time to prepare for phone theft is before it happens.

1. Use a strong screen lock

Avoid simple PINs such as:

• 1234
• 0000
• Your birth year
• Your phone number

Use a strong PIN, password or biometric protection.

2. Turn on device tracking

Android users should ensure Find Hub is configured.

iPhone users should enable Find My.

3. Enable two-factor authentication

Use two-factor authentication on important accounts such as:

• Google
• Apple
• Email
• Social media
• Banking services

4. Keep your IMEI somewhere safe

Do not wait until the phone disappears to look for its IMEI.

Save it somewhere secure.

You can also keep the original phone box and purchase receipt.

5. Back up important information

A stolen phone should not also mean losing all your photographs, contacts and documents.

Use reputable cloud backup services.

6. Don’t store sensitive information in plain sight

Avoid keeping passwords, PINs, ID numbers or banking information in an unprotected notes application.

7. Protect your SIM

Make sure your mobile registration information is accurate and understand your operator’s procedures for replacing a lost SIM.

What Should You Do If You Recover the Phone?

If you recover the phone after reporting it stolen, contact your mobile provider and explain the situation.

If the device was remotely erased, you may need to set it up again.

For an Android device, Google says you will need your Google Account password after a factory reset performed through Find Hub.

For an iPhone, do not remove the device from Find My simply because you have recovered it. First make sure the device and your Apple Account are secure.

Frequently Asked Questions

Can I block my stolen phone using the IMEI number?

The IMEI identifies the mobile device. In Kenya, you should provide the IMEI to your mobile network operator when reporting a stolen device and ask about the applicable blocking process. Google also confirms that mobile providers can use the IMEI to disable supported Android devices.

How do I find my IMEI without the phone?

For Android, Google says the IMEI can be viewed through Find Hub for supported devices. You can also check the original box, receipt or other device records.

Can I track a stolen phone using the IMEI?

The IMEI is primarily a device identifier. It is not the same thing as a consumer-facing GPS tracking service. Use Android Find Hub or Apple’s Find My to locate your device where available, and involve law enforcement if the location indicates a stolen device.

Should I erase my stolen phone?

Consider remote erasure if you believe you cannot recover the phone and your personal information is at risk. But understand that Android’s Find Hub will no longer provide location information after the device has been erased.

For an iPhone, Apple also warns that remote erasure cannot be undone, so consider your recovery options first.

What should I do if someone calls saying they found my phone?

Be careful. Do not disclose your phone passcode, Apple Account password, Google password, M-PESA PIN or verification codes.

If someone claims to have found the device, arrange any recovery through a safe and appropriate channel rather than meeting a suspected thief alone.

Can a thief access my M-PESA if they steal my phone?

It depends on the security controls in place and what the thief can access. Treat a stolen phone connected to mobile money as an urgent security incident. Contact your mobile operator immediately and protect the account.

What if my phone was stolen while it was unlocked?

Treat this as particularly urgent.

Immediately:

1. Lock the device remotely.
2. Contact your mobile provider.
3. Protect your mobile-money account.
4. Change important account passwords.
5. Review banking and financial activity.
6. Report the theft.

Can I recover my stolen phone?

Possibly, but there is no guarantee.

Use the official tracking tools available for your device and report the theft to the police. If a location appears, don’t attempt a confrontation yourself.

Final Advice: Act Fast, But Don’t Put Yourself at Risk

A stolen smartphone is more than a lost piece of hardware. For many Kenyans, the phone is also the gateway to M-PESA, banking, email, social media, work documents, photographs and personal information.

The safest response is therefore to treat phone theft as both a device-security problem and an account-security problem.

Lock the phone. Block the SIM. Protect your money. Secure your accounts. Report the theft. Keep your IMEI.

And most importantly, never risk your personal safety trying to recover a phone yourself.
