Phone Stolen? What to Do Immediately in the UK (2026 Guide)

Phone theft is a serious problem in the UK

Mobile phone theft is not simply about someone taking an expensive piece of technology.

Modern smartphones can provide access to personal emails, payment services, photographs, documents and important account-recovery tools.

Consequently, a stolen phone can create financial and privacy risks even when the device itself remains locked.

In October 2026, the National Police Chiefs’ Council reported the results of a major operation targeting phone theft and the resale of stolen devices.

Stolen phones: what police reported in October 2026

Operation Reckoning involved 17 police forces across England and Wales.

During September, officers carried out more than 700 visits to second-hand mobile phone shops. The aim was to support legitimate businesses, identify suspicious activity and disrupt the market for stolen handsets.

Meanwhile, the Metropolitan Police recorded 705 arrests and recovered 281 suspected stolen phones during the operation.

Police also called for stronger measures to make stolen phones harder to use and resell.

These figures highlight why phone theft matters not only to individual victims but also to the wider mobile phone industry.

Why stolen phones remain attractive to criminals

Even older smartphones can retain significant resale value.

A thief may attempt to sell a handset directly, pass it through another person or move it into the wider second-hand market.

However, modern security features make unauthorised access and resale more difficult in many situations.

For example, Apple Activation Lock can prevent someone from activating an iPhone without the relevant owner’s credentials.

Similarly, network-level IMEI blocking can restrict a handset’s access to participating cellular networks.

Those protections serve different purposes. Therefore, owners and businesses should understand how they work together.

Phone stolen in the UK: what to do in the first few minutes

The first priority is your personal safety.

If someone snatches your phone, do not chase them into traffic or confront them over the handset.

Instead, move somewhere safe and ask for assistance if necessary.

The police specifically advise people not to put themselves at risk when a phone is stolen.

Try to locate your stolen phone safely

If you have access to another device, open the relevant phone-location service.

For iPhone users, that is Apple’s Find My system.

For Android users, Google’s Find Hub offers similar features on supported devices.

These services may show the phone’s location or last known position.

However, location information is not always exact, and the device may not currently be reachable.

If the location suggests that someone has stolen the handset, pass that information to the police rather than attempting to recover it yourself.

Lock the stolen handset remotely

Next, use the available remote-lock feature.

This can make it harder for someone to access the device while you investigate what happened.

Importantly, remote locking and network IMEI blocking are different actions.

Remote locking protects access to the handset. Meanwhile, IMEI blocking targets cellular-network use.

Stolen iPhone: how to find and lock it

Apple provides several tools for people who lose an iPhone.

If you previously enabled Find My, you can use another Apple device or sign in through the web.

Apple explains the process in its official lost iPhone guidance.

Step 1: Open Find My for your stolen iPhone

On another Apple device, open the Find My app.

Alternatively, visit:

Sign in using your Apple Account.

Apple allows access to Find Devices without the usual verification code through the appropriate web sign-in option, which can help if your missing phone was your trusted device.

Step 2: Select your missing iPhone

Choose the handset from the list of associated devices.

If Apple can determine its location, the service may display that information on a map.

However, the phone must meet the relevant location-service requirements.

If no current position is available, check whether the service shows a last known location.

Step 3: Activate Lost Mode

Next, select the option to mark the device as lost.

Apple’s Lost Mode locks the phone using its passcode and suspends the relevant Apple Pay cards and passes.

You can also display a message and contact details so someone who finds the handset can reach you.

Consequently, Lost Mode helps protect the device while providing a possible route for its return.

Step 4: Keep Activation Lock enabled

This step is particularly important.

Apple warns users not to remove a stolen iPhone from Find My simply because they can no longer locate it.

Removing the device from the account can also remove Activation Lock, making it easier for someone else to activate and resell the handset.

Furthermore, if you have AppleCare+ with Theft and Loss, Apple advises keeping the relevant account and Find My connection in place until the claim receives approval.

Step 5: Consider remote erasure

If you believe the device will not return, you may decide to erase it remotely.

However, Apple warns that this action cannot be undone.

Therefore, consider the implications for your data and recovery options before proceeding.

Even after remote erasure, follow Apple’s instructions for keeping the appropriate Activation Lock protection active.

Stolen Android phone: how to find and lock it

Android users can use Google’s Find Hub service to locate, secure or erase supported devices.

The service works through the Google Account associated with the handset.

However, the available actions depend on the device, its settings and connectivity.

Step 1: Open Google Find Hub

Use another device to visit:

Sign in with the Google Account associated with your missing phone.

Alternatively, use the Find Hub app on another compatible Android device.

Step 2: Select the stolen Android handset

Choose the relevant device.

Google may show its current or last known location, depending on the available information.

Some supported Android devices can also benefit from offline-finding features.

Nevertheless, there is no guarantee that every missing phone can be located after it loses connectivity.

Step 3: Mark the Android device as lost

Google’s Mark as lost feature helps secure the handset with its existing screen-lock credentials.

Where supported, you can display a contact message on the lock screen.

This can help someone return a genuinely misplaced phone without gaining access to personal applications.

Step 4: Erase the device if necessary

Find Hub also supports remote erasure where the device meets the applicable requirements.

However, Google warns that erasing a handset removes its data and ends normal Find Hub location availability for that device.

In addition, a factory reset may not erase removable SD storage.

Therefore, carefully consider whether remote erasure is appropriate.

Read Google’s official Find Hub instructions for the current procedure.

Phone stolen while unlocked: how to protect your accounts

This situation creates a more urgent account-security concern.

For example, someone could grab a handset while you are using an application or reading messages.

Alternatively, they may have watched you enter your passcode before taking the phone.

Police.uk specifically warns about criminals observing passcodes in public places, a tactic sometimes called shoulder surfing.

Secure your main email account

Your email account often provides access to password resets for other services.

Consequently, it deserves immediate attention if someone may have accessed your unlocked phone.

Use another trusted device to change the relevant password and review active sessions.

Where available, sign out unfamiliar devices and update account-recovery settings.

Protect banking apps after phone theft

Contact your bank immediately if someone could access banking applications, payment information or verification codes.

Explain that your handset was stolen and that you are concerned about unauthorised access.

Your bank can advise on appropriate security steps, account restrictions and any suspicious transactions.

Do not wait for money to disappear if you have credible reasons to believe the account is at risk.

Review other important accounts

Next, consider messaging services, social media, password managers and other applications linked to your phone.

Where appropriate, change passwords and revoke access from the missing device.

Also, check whether someone could receive SMS verification codes through the stolen SIM or eSIM.

For this reason, contacting your mobile network is an important part of the response.

How to block a stolen phone using its IMEI

Every cellular handset has an International Mobile Equipment Identity, commonly called an IMEI.

This identifier helps distinguish a handset from other devices.

According to Police.uk, UK mobile networks can use an IMEI to prevent a stolen handset from accessing their networks.

Where can you find a stolen phone’s IMEI?

If you still have the handset, dialling *#06# usually displays its IMEI information.

However, if someone has already stolen the phone, you may find the number elsewhere.

For example, check:

• The original phone packaging.
• Purchase invoices or device records.
• Your network account or relevant handset documentation.
• Apple or Google device information where available.
• Business asset registers if your employer owns the handset.

Some phones have more than one IMEI, so record the relevant identifiers where possible.

Contact your network to block the stolen phone

Tell the provider that someone has stolen your handset.

Ask it to suspend the relevant mobile service and explain the available IMEI-blocking process.

The operator may need to verify your identity and confirm the handset information.

Additionally, ask how to obtain a replacement SIM or eSIM when you are ready to use another device.

What happens when a stolen phone’s IMEI is blocked?

A network-level IMEI block aims to prevent the handset from connecting to participating cellular networks.

Consequently, a different SIM card does not automatically remove the restriction.

However, an IMEI block is not a complete device shutdown.

For example, the phone may still connect to Wi-Fi or perform other functions that do not require cellular service.

Blocking also does not automatically erase personal photographs or reveal the device’s location.

Can you track a stolen phone using its IMEI?

Not through an ordinary public IMEI lookup.

An IMEI identifies cellular equipment, but it does not give consumers a public live-location service.

Therefore, be cautious about websites that promise to reveal a stolen phone’s precise location simply after you enter its IMEI.

Some services may charge fees without providing the recovery information they advertise.

Instead, use the manufacturer’s authorised location tools and provide the IMEI to the police and mobile operator where appropriate.

Does IMEI blocking help the police?

An accurate IMEI can help police identify a specific handset during a theft investigation.

For example, officers may need to establish whether a recovered device matches one reported stolen.

However, blocking the IMEI does not guarantee that police will locate or recover the phone.

The purpose of network blocking is primarily to restrict cellular use on participating networks.

How to report a stolen phone to UK police

Report the theft promptly through the appropriate police channel.

If the incident involves immediate danger, violence or an ongoing emergency, call 999.

For non-emergency theft, you can generally report the incident through your local police force’s website or by calling 101.

What information should you provide?

Include the handset’s make, model and IMEI where available.

Also explain when and where the theft happened, along with any useful witness or location information.

If someone has accessed bank accounts or made suspicious transactions, tell the police about those concerns too.

However, do not attempt to investigate a suspected thief yourself.

Why the crime reference number matters

Keep the crime reference number after reporting the incident.

Your insurer may request it when assessing a theft claim.

Furthermore, it creates a record that you reported the loss through the appropriate channel.

Police.uk provides further guidance in its official mobile phone security guide.

Can a stolen phone still be sold?

Unfortunately, stolen smartphones can still enter the second-hand market.

However, device-status checks, activation locks and accurate purchasing records can make that process harder.

The October 2026 police operation specifically focused on the movement of stolen devices through resale channels.

Officers also visited legitimate second-hand phone businesses to promote appropriate purchasing checks and responsible trading.

Why a stolen phone may look completely normal

A handset does not necessarily show visible signs of theft.

For example, an expensive smartphone may have a perfect screen, original packaging and excellent battery condition.

However, those details do not establish that the person offering it has the right to sell it.

Consequently, retailers should investigate relevant device-status information before purchasing valuable used stock.

How phone shops can check a stolen phone’s IMEI status

Professional buyers can use services such as MobiCHECK to investigate available IMEI and device-status information.

For example, a retailer may want to check for relevant loss, theft, network-block or finance indicators.

This helps staff identify reasons to pause a transaction or request further evidence.

However, a clear IMEI result does not guarantee that nobody will report new information later.

Therefore, professional due diligence should also include appropriate seller records and internal purchasing policies.

Why stolen phones create a bigger problem for businesses

For an individual, losing one valuable handset is stressful and potentially expensive.

However, a business may be responsible for hundreds or thousands of mobile devices.

Those devices might belong to employees, rental customers, contractors or other organisations.

Consequently, the financial exposure can increase considerably.

Stolen employee phones and corporate fleets

Imagine a company issues smartphones to 200 employees.

Each handset provides access to corporate email, work applications and customer information.

If an employee loses a device, the employer may need to protect both the physical asset and the information accessible through it.

For this reason, businesses should maintain accurate device records and clear incident-response procedures.

Lost or stolen rental phones

Rental providers face a different challenge.

They may retain ownership of a handset while the customer has permission to use it during the agreement.

Most customers return their devices correctly.

However, a small proportion may become lost, stolen or remain unreturned.

Consequently, the rental company needs an appropriate way to record its ongoing interest and investigate genuine loss or theft.

Phone finance providers

Some finance arrangements involve an ongoing financial or contractual interest in the handset.

However, a future buyer may not know that an agreement remains active.

For eligible organisations, recording the relevant status against the IMEI can improve visibility when the handset enters the used-device market.

Importantly, an active finance interest is not the same thing as a theft report or network block.

How MobiBLOCK helps protect stolen and at-risk business phones

MobiBLOCK is MobiCode’s IMEI-based device-blocking and asset-protection service for businesses.

It helps eligible organisations record device interests, request qualifying network blocks and maintain a clearer evidence trail.

For example, a company may want to record its ownership of rental handsets or respond to an eligible theft involving business property.

Unlike ordinary consumer phone-recovery services, MobiBLOCK is designed around business asset management and authorised device-status actions.

MobiBLOCK ownership and finance markers from 10p

MobiCode currently advertises General List markers from 10p per device.

These markers allow eligible organisations to record relevant ownership, finance, rental or lease interests against an IMEI.

Consequently, participating businesses checking the handset may identify that another organisation holds an active interest.

This can provide an opportunity to investigate before buying or processing the phone.

However, an interest marker does not itself disable the handset or guarantee its recovery.

MobiBLOCK UK network blocking for £1

MobiBLOCK also offers a separate network-blocking request service for £1 per eligible lost or stolen handset.

Where the request qualifies and the relevant networks apply the block, the device may lose cellular access on participating UK networks.

For an organisation that has suffered a genuine theft, this creates another potential device-protection measure alongside existing reporting and recovery procedures.

However, not every late rental return, disputed invoice or customer complaint qualifies for network blocking.

Businesses must establish the appropriate evidence, eligibility and authority first.

Remove a marker or block when the issue is resolved

MobiCode currently advertises free removal when the relevant marker or qualifying block no longer applies.

For example, a rental company may recover a missing handset and resolve the underlying issue.

In that situation, the organisation should ensure its device-status records reflect the new circumstances.

Accurate records are important because inappropriate or outdated restrictions can affect legitimate users.

How much could MobiBLOCK cost a business?

For businesses managing large fleets, device-level record costs can be relatively small compared with the value of the assets involved.

Consider a company that rents 1,000 smartphones.

If all 1,000 handsets qualify for a General List marker at MobiCode’s published starting price of 10p each, the calculation is straightforward.

Of course, that does not mean the company has insured every device against theft or guaranteed that missing stock will return.

Instead, it means the business has created eligible device-level interest records that participating trade organisations may see during checking.

What about stolen or lost devices?

Suppose the same company experiences five genuine theft incidents involving eligible handsets.

At the current advertised £1 request price, five qualifying network-blocking submissions would cost £5 before any applicable VAT or other terms.

However, successful blocking depends on the service’s eligibility and participating-network arrangements.

Therefore, the business should evaluate MobiBLOCK as one part of its wider asset-protection process, not as insurance or guaranteed recovery.

MobiBLOCK vs MobiCHECK: what’s the difference?

The two products help different organisations at different points in the device lifecycle.

MobiBLOCK helps an eligible business record an interest or request appropriate action against an at-risk device.

By contrast, MobiCHECK helps another business investigate available device-status information before buying, trading or processing a handset.

MobiBLOCK: record and act

For example, a rental company may want to record its legitimate interest in a handset that remains part of its fleet.

Where a device qualifies for blocking following a genuine theft or loss, the organisation can also explore the relevant request route.

MobiCHECK: investigate before buying

A second-hand retailer may encounter the same handset later.

By using MobiCHECK, staff can investigate whether available records indicate an active interest or relevant network block.

Consequently, the buyer may gain a reason to request further evidence before committing money.

MobiCode states that MobiCHECK can surface relevant MobiBLOCK flags and blocks.

However, the available data and timing of updates still matter. No checking service can guarantee that an IMEI’s status will never change.

IMEI blocking vs remote locking vs remote wiping

These protections solve different problems.

For example, a business might need to protect customer information, prevent unauthorised account access and respond to the loss of an expensive company handset.

No single security control necessarily addresses every concern.

Businesses should therefore apply controls based on the actual incident rather than assuming every missing device requires the same response.

Company phone stolen: protecting business data

Business-owned phones can create a separate information-security issue.

For example, a stolen handset might contain customer details, work messages or access to internal systems.

Consequently, the employer may need to investigate whether the theft created a personal data breach.

Secure business accounts and access

First, follow the organisation’s incident-response procedure.

IT staff should consider revoking relevant sessions, changing compromised credentials and applying appropriate mobile-device-management controls.

Where supported and necessary, the organisation may be able to remotely lock or wipe the device.

The National Cyber Security Centre provides guidance on managing and erasing deployed devices.

Does every stolen work phone need reporting to the ICO?

No. The theft of a company phone does not automatically mean the organisation must notify the Information Commissioner’s Office.

Instead, the organisation must assess whether a personal data breach occurred and the likely risk to individuals.

Under UK GDPR, organisations must report a notifiable personal data breach without undue delay and, where feasible, within 72 hours of becoming aware of it.

If the breach is unlikely to create a risk to people’s rights and freedoms, an ICO notification may not be necessary. However, the organisation must still document the breach and its assessment.

See the ICO’s personal data breach guidance for the relevant requirements.

Where MobiBLOCK fits

Remote locking and data erasure focus on information security.

MobiBLOCK provides a separate device-status control for eligible business assets.

Consequently, an organisation may use several measures when responding to a stolen company handset.

However, an IMEI block does not replace the need to protect accounts, assess data exposure or meet relevant legal obligations.

How to prevent your phone from being stolen

Although nobody can guarantee that a phone will never be stolen, simple precautions can reduce certain risks.

Police.uk recommends several practical security measures.

Keep your phone secure in public

Be aware of your surroundings when using a phone near roads, stations and busy public areas.

For example, criminals on bicycles or mopeds may attempt to snatch devices from people who are distracted.

When possible, avoid standing close to the roadside while looking down at your screen.

Use a strong screen lock

Choose a strong passcode or password and use supported biometric security.

Additionally, configure the handset to lock automatically after a short period.

A stronger screen lock can make casual unauthorised access more difficult.

Enable manufacturer theft protection

On supported iPhones, Apple’s Stolen Device Protection adds safeguards around certain sensitive actions.

Meanwhile, supported Android phones offer theft-protection features such as Theft Detection Lock.

However, availability varies by device and software version.

Therefore, review the manufacturer’s current guidance for your handset.

Save your IMEI somewhere safe

Record the IMEI in a secure place separate from the device itself.

You may need this information when contacting the police, insurer or mobile operator.

For businesses, keeping an accurate inventory of device identifiers also makes loss investigations easier.

How phone shops can avoid buying stolen phones

Professional buyers need a clear process for dealing with devices that raise concerns.

For example, the seller may be unable to explain the phone’s ownership or the IMEI check may return a relevant warning.

However, a warning does not automatically prove that the person committed a crime.

Instead, businesses should pause the transaction and follow their internal due-diligence and escalation procedures.

Check the IMEI before paying

First, identify the handset and confirm its IMEI.

Next, carry out appropriate device-status checks and review the seller’s information.

For example, MobiCHECK can help professional businesses investigate relevant status records before committing to a purchase.

Keep appropriate transaction records

Record the information necessary for the transaction and the business’s legal obligations.

However, collect and retain personal information proportionately and securely.

Clear records can support investigations if a device later develops a relevant status problem.

Escalate suspicious cases properly

If the evidence raises serious concerns, follow the organisation’s policy and the appropriate reporting route.

Do not accuse someone of theft merely because a handset is inexpensive or a status check requires further investigation.

Instead, base decisions on verifiable information.

Phone stolen? Protect the device and the information inside it

If someone steals your phone, acting quickly can reduce the risk of further harm.

Start with personal safety. Then use the relevant manufacturer tools to secure the handset, protect important accounts and contact your mobile operator.

Afterwards, report the theft to the police and contact your insurer if appropriate.

For businesses, the response may require additional measures.

Accurate device inventories, appropriate tracking, account-security controls and documented incidents all help organisations manage mobile assets.

MobiBLOCK adds another layer by allowing eligible businesses to record ownership or financial interests and request qualifying UK network blocking.

However, the objective should always be proportionate, evidence-led device protection rather than automatically blocking every disputed handset.
