Introduction
Losing your mobile phone or having it stolen can be both stressful and disruptive, but acting quickly is essential to protect your personal information and finances. In the UK, a lost or stolen phone isn’t just an inconvenience – it can also put you at risk of fraud, identity theft, and unauthorised use of your accounts. Criminals may try to access your emails, banking apps, or other sensitive data stored on your device, so immediate action helps limit the potential damage.
This page will guide you step-by-step through what to do if your mobile phone goes missing. You’ll learn how to secure your data, report the loss to the right authorities, and manage your mobile service to prevent further misuse. We’ll also explain your legal rights and responsibilities as a UK mobile phone user, including how your phone, internet and TV service rights may affect what your provider can do to help.
Understanding your obligations – such as reporting the loss promptly and cooperating with your service provider – can make a significant difference in minimising financial loss and ensuring you get the right support. Whether you’re worried about unauthorised charges, protecting your personal data, or replacing your device, the following sections will provide clear, practical advice tailored for UK users.
Immediate Steps to Take When Your Phone is Lost or Stolen
Losing your mobile phone or having it stolen can be stressful, but acting quickly can help protect your personal information and reduce the risk of financial loss. Here are the immediate steps you should take if your phone goes missing in the UK:
1. Try to Locate Your Phone
Many smartphones come with built-in tracking features, such as Find My iPhone for Apple devices or Find My Device for Android phones. If you’ve enabled these services, log in from a computer or another device as soon as possible. You may be able to see your phone’s last known location, play a sound to help find it nearby, or display a message on the screen. If your phone is switched off or offline, you might still see its last recorded position.
2. Contact Your Mobile Network Provider
As soon as you realise your phone is lost or stolen, contact your mobile network provider. They can block your SIM card to prevent anyone else from making calls, sending texts, or using your data. This is essential for managing call costs and avoiding unexpected charges if your phone falls into the wrong hands.
3. Request to Block Your Phone
Ask your provider to block the handset itself, not just the SIM card. This is done using your device’s unique IMEI number (International Mobile Equipment Identity). Blocking the phone means it can’t be used on any UK network, making it less valuable to thieves. Your provider can advise you on how to do this and what information they need.
4. Change Passwords for Important Accounts
Your phone is likely linked to sensitive accounts, such as email, social media, and banking apps. Change your passwords as soon as possible, especially for accounts that could be used to access personal or financial information. This helps protect your identity and finances if someone tries to access your data.
5. Consider Remotely Wiping Your Phone
If you’re unable to recover your phone, consider using remote wipe features if your device supports them. This will erase all data from your phone, including contacts, messages, photos, and stored passwords. Check your device’s settings or your provider’s website for instructions on how to do this.
6. Keep a Record of Your IMEI Number
Your IMEI number is a 15-digit code unique to your device. You can usually find it on the original packaging, on your phone’s box, or by checking your account with your network provider. Having this number handy is crucial for reporting the loss to your provider and the police, and for blocking the device.
Additional Tips
Report the loss or theft to the police, especially if you need a crime reference number for insurance or if your phone has been stolen.
Check if you have mobile phone insurance that could help you recover the cost of your device or cover unauthorised usage.
Taking these immediate steps can help you stay in control after losing your phone and minimise the impact on your privacy and finances. For more advice on what to do next, explore related topics such as mobile phone insurance and managing call costs.
Reporting Your Lost or Stolen Phone
When your mobile phone is lost or stolen, reporting the incident quickly is crucial to protect your personal information, prevent unauthorised use, and support any insurance or contract claims. Here’s what you need to do:
1. Report to Your Mobile Network Provider
Contact your mobile network provider as soon as possible. They can block your SIM card and the phone itself, preventing anyone else from making calls, sending texts, or using your data. Most providers have a dedicated lost or stolen phone helpline, which you can find on their website or by calling customer services.
Reporting promptly helps limit your liability for any unauthorised charges. Under UK law, once you report your phone as lost or stolen, you should not be held responsible for charges run up after that point. However, you may still be liable for some charges made before you notify your provider, so acting fast is important. For more detail on your rights and what your provider must do, see your rights with phone services.
2. Report to the Police
If your phone has been stolen, or if you need a crime reference number for insurance purposes, report the theft to your local police. You can usually do this online or by visiting a police station. Be prepared to provide:
The make, model, and colour of your phone
The phone’s IMEI number (usually found on the original box, receipt, or in your phone’s settings)
The approximate time and place where the phone was lost or stolen
Any distinguishing features or marks on your device
The police will give you a crime reference number, which is essential if you want to make an insurance claim or request a contract cancellation due to theft.
3. Insurance and Contract Considerations
Many insurance companies require a police report when you make a claim for a lost or stolen phone. Similarly, if you want to cancel your phone contract because your device was stolen, your provider may ask for evidence that you have reported the theft to the police.
4. Keep Records
Make sure to keep copies of all reports, reference numbers, and communications with your network provider and the police. These documents can be crucial if you need to follow up on your claim, dispute any charges, or provide proof of your actions.
By following these steps, you’ll help protect yourself from further loss and make the process of replacing your phone or making a claim as smooth as possible.
Protecting Yourself from Fraud and Unauthorised Charges
Losing your mobile phone puts you at risk of fraud and unauthorised charges. If someone gains access to your device, they may be able to make calls, send messages, or use your data, potentially racking up significant costs on your account. In some cases, criminals may also attempt to access your personal information or financial details stored on your phone.
Steps to Limit Your Liability
To reduce the risk of unauthorised use and limit your liability for any charges, act quickly:
Contact your mobile provider immediately – Report the loss or theft as soon as possible. Your provider can block your SIM card and device, stopping anyone else from making calls, sending texts, or using data on your account.
Request a block on your device using its IMEI number – The IMEI (International Mobile Equipment Identity) is a unique number for your phone. Blocking the IMEI will prevent your device from being used on any UK network, even with a different SIM card.
Change passwords for important accounts – If your phone had access to email, banking, or social media apps, change your passwords right away to prevent unauthorised access.
Most UK mobile providers have policies that limit your liability for unauthorised charges if you report the loss or theft promptly – usually within 24 hours. However, you may be liable for some charges incurred before you report the phone missing, so acting quickly is essential.
Monitor Your Bills and Spot Suspicious Activity
Keep a close eye on your phone bills and account statements after your phone goes missing. Look out for:
Unfamiliar calls or texts, especially to premium-rate or international numbers
Unusual data usage
Charges for services or purchases you didn’t authorise
If you notice anything suspicious, contact your provider immediately. You may also have the right to challenge any unauthorised or incorrect charges by disputing a phone bill.
Recognising and Avoiding Scams
Unfortunately, losing your phone can make you a target for scams. Fraudsters may try to contact you pretending to be your network provider or the police, asking for personal details or payment to “help” recover your phone. To protect yourself:
Never share your passwords, PINs, or bank details with anyone who contacts you unexpectedly.
Be wary of emails or texts that ask you to click on links or provide sensitive information.
Only use official contact details for your provider – never those sent in a suspicious message.

What to Do If You Suspect Fraud or Unauthorised Use
If you think someone has used your phone fraudulently or accessed your accounts:
Report it to your mobile provider straight away and ask them to investigate.
Change passwords for any accounts that may have been accessed.
Report the incident to your bank if you believe your financial information is at risk.
Consider reporting the fraud to Action Fraud, the UK’s national reporting centre for fraud and cybercrime.
If you have been affected by a scam or are struggling with the consequences, support is available. Find out more about getting help after scams.
By taking prompt action and staying vigilant, you can protect yourself from further harm and minimise the impact of losing your phone.
Understanding Your Rights and Responsibilities
When your mobile phone is lost or stolen, it’s important to understand both your rights and your responsibilities under UK law and your mobile contract. Acting quickly and knowing what you’re entitled to can help protect you from unnecessary charges and make the process smoother.
Your Responsibilities
You are responsible for reporting the loss or theft of your phone to your network provider as soon as possible. Prompt reporting limits your liability for any unauthorised use of your phone. Most providers have a dedicated line for lost or stolen phones, and you should also report the incident to the police to obtain a crime reference number. This is especially important if you need to make an insurance claim.
If you delay reporting, you could be held responsible for any charges made on your phone until the point you notify your provider. In some cases, failing to report the loss promptly may also affect your rights to claim back unauthorised charges or to make an insurance claim.
Your Rights Regarding Unauthorised Charges
Under UK law, you are protected against unauthorised charges made after you report your phone as lost or stolen. Once you notify your provider, you should not be liable for any further charges, except in cases where you have acted negligently (for example, by sharing your PIN or password). Before you report the loss, you may be responsible for charges up to a certain limit – often capped at £100 for unauthorised calls or data usage, depending on your provider’s policy.
If you believe you have been unfairly charged, you have the right to dispute these charges with your provider. For a broader overview of your rights and what your provider must do, see our guide to phone, internet and TV service rights.
Contractual Obligations and Ongoing Charges
Losing your phone does not automatically end your contract or your obligation to pay your monthly fees. You are still responsible for any outstanding charges, including your monthly line rental, until you formally end or change your contract. Check your contract for details about early termination fees or device repayment plans, as you may still owe money on the handset or service.
Some providers offer options such as pausing your contract, providing a replacement SIM, or allowing you to transfer your number to a new device. If you’re considering changing your provider after a loss, our page on switching your phone provider explains your options and what to expect during the process.
Cancelling or Switching Your Contract
If you decide you no longer want to continue with your current provider after your phone is lost or stolen, you may have the right to cancel your contract. However, you should review your contract terms carefully, as cancellation may involve fees or notice periods. For step-by-step advice on how to end your agreement, visit our guide on cancelling your phone contract.
Importance of Reviewing Your Contract and Provider Policies
Every mobile contract is different, and service providers may have specific rules about lost or stolen phones. Take time to read your contract and your provider’s policies so you understand your obligations, any limits on liability, and what support is available. Knowing these details can help you make informed decisions and avoid unexpected costs.
If you’re unsure about your rights or need more information, our resources on phone, internet and TV service rights provide further guidance on how to protect yourself and what to expect from your provider.
Managing Your Mobile Service After Loss or Theft
After your mobile phone is lost or stolen, it’s important to take control of your mobile service to avoid unwanted charges and protect your finances. Here’s what you need to know about managing your account, switching providers, handling outstanding bills, and updating your services.
Continue, Suspend, or Cancel Your Mobile Service
First, contact your network provider as soon as possible. They can suspend your service to stop anyone else using your phone and running up charges. You’ll still be liable for any charges made before you report the loss, but most providers will not hold you responsible for unauthorised usage after you’ve notified them.
If you decide not to replace your phone immediately, you might want to cancel your contract altogether. Be aware that ending a contract early may involve cancellation fees, depending on your agreement’s terms. If you’re on a pay-as-you-go plan, you can simply stop topping up your account.
Switching Providers or Changing Your Contract
Losing your phone is a good opportunity to review your current deal. You may want to consider switching phone providers if you’re unhappy with your current service or want a better deal. You can keep your existing number by requesting a PAC (Porting Authorisation Code) from your provider.
If you have broadband or TV services bundled with your mobile, exploring bundle switching to save costs could help you find a more affordable package or improved service.
Dealing with Outstanding Bills and Charges
You’re generally responsible for any charges made on your phone until you report it lost or stolen, so act quickly. If you find yourself struggling to pay your phone bill as a result of unexpected costs, there are steps you can take to get help and manage your payments. Providers are required under Ofcom guidelines to support customers facing financial difficulty, so don’t hesitate to reach out.
Replacing Your Phone and Updating Your Service
Once you’re ready to replace your phone, contact your provider to activate a new SIM card and transfer your number and remaining balance (if applicable). If you had insurance, check your policy to see if you’re entitled to a replacement device.
You may need to update your contract, especially if you’re upgrading or switching to a different handset. Always review the terms before agreeing to a new plan.
Handling Apps, Software, and Downloads
Losing your phone can affect access to apps, subscriptions, or purchased downloads. If you experience problems with apps or software after setting up your new device, there are steps you can take to recover access or troubleshoot issues. Remember to sign out of your accounts on the lost device remotely if possible, and change passwords to keep your information secure.
Protecting Your Data on a New Device
When you get a new phone, take steps to protect your personal data. Set up a strong PIN or biometric security, enable remote tracking and wiping, and regularly back up your data. If you use apps for banking or payments, ensure they’re set up securely and monitor your accounts for any unusual activity.
By managing your mobile service promptly and carefully, you can minimise disruption and protect yourself from further inconvenience or financial loss.
How Mobile Phone Insurance Can Help
Having mobile phone insurance can offer valuable peace of mind if your device is lost or stolen. Insurance is designed to help cover the financial cost of replacing your phone and, in some cases, any unauthorised use. This protection can be especially helpful given the high price of modern smartphones and the inconvenience of being left without a working device.
What Does Mobile Phone Insurance Typically Cover?
Most mobile phone insurance policies cover loss, theft, and accidental damage. If your phone is stolen or goes missing, your insurer may provide a replacement device or reimburse you for its value, up to certain limits. Some policies also include cover for unauthorised calls or data usage made after the phone is lost or stolen, though there is often a cap on the amount paid out.
It’s important to note that insurance policies vary, so always check what is included. Some only cover theft if there are signs of forced entry or violence, while others may require you to report the loss to the police and your network provider within a set timeframe.
How to Check Your Policy and Make a Claim
If your phone is lost or stolen, review your insurance documents carefully to understand your coverage and the claims process. Policies are often provided through your mobile network, a standalone insurer, or as part of a bank account package. Look for details on:
What is covered (loss, theft, accidental damage)
Any excess you need to pay
Claim limits or exclusions
Required documentation, such as a police crime reference number or proof of purchase
To make a claim, contact your insurer as soon as possible. You’ll usually need to provide evidence of the loss or theft, such as a police report, and may be asked for your phone’s IMEI number. Follow the insurer’s instructions closely, as missing deadlines or paperwork could affect your claim.
Common Exclusions and Important Considerations
There are often exclusions in mobile phone insurance policies. Common exclusions include:
Not reporting the loss or theft to the police or your network provider quickly enough (often within 24-48 hours)
Leaving your phone unattended in public places
Not taking reasonable care to prevent loss or theft
Claims for older devices or those not registered on the policy
Before purchasing insurance, read the terms and conditions thoroughly. The Financial Conduct Authority (FCA) has reviewed mobile phone insurance products and found that some policies have unclear terms or do not handle claims and complaints well. If you have concerns about your insurer or the claims process, you can start by making a complaint directly to the company named on your policy documents. If you’re not satisfied with their response, you can escalate the matter as outlined by the FCA.
Should You Consider Mobile Phone Insurance?
While mobile phone insurance isn’t a legal requirement, it can be a worthwhile part of your phone protection strategy, especially if you rely on your device for work or personal use. Weigh up the cost of insurance against the potential cost of replacing your phone. Also, check whether your home insurance, bank account, or credit card already provides some level of cover, as you may not need a separate policy.

By understanding your policy and knowing how to make a claim, you can act quickly and confidently if your phone is ever lost or stolen.
Additional Resources and Support
If your mobile phone has been lost or stolen, knowing where to turn for help and advice can make a stressful situation easier to manage. Here are some useful contacts and resources to support you through the process:
Useful Contacts
Your Network Provider: Contact your mobile network provider as soon as possible to report the loss or theft. They can block your SIM card, prevent unauthorised use, and may help you track or lock your device remotely.

Further Help and Information
Losing your phone may also mean you need to manage or cancel related services – such as subscriptions or contracts.
