Our step-by-step guide for when your phone is lost or stolen.

Losing your phone feels like losing your lifeline. But knowing what to do next can make a massive difference. Whether it’s slipped out of your pocket on the bus or been swiped from a table at a café, the panic is real. Don’t worry though. There are clear steps you can take to protect your data, stop your phone being misused and get back up and running as fast as possible. 

 

Lock and locate your device immediately.

 

 

The first thing to do is to track your phone. Both Apple and Android devices come with built-in tools that’ll help you locate, lock or even erase your phone remotely. If you’re using an iPhone, head to Find My iPhone. For Android users, Find My Device is your go-to. 

These features let you see your phone’s location on a map, lock it down and display a message on screen – like a contact number or ‘this phone is lost’. If things look serious you could also wipe your data remotely to protect your privacy. 

If you didn’t have location tracking turned on, don’t panic. You can still secure your accounts and contact your network provider. And for the future, make sure you switch these features on and keep your location services enabled too. You’ll appreciate it later on if something bad happens. 

 

Report the loss to iD Mobile.

 

 

Once you’ve tried to locate your phone, your next move is to secure your SIM card with us. This is a crucial step. By suspending your SIM, you instantly block anyone from making calls, sending texts, or using your data. It’s the single best way to protect yourself from unexpected charges, especially if you think your phone has been stolen.

We can also get a replacement SIM sent out to you, and don’t worry – you’ll keep your existing number, making it much easier to get back online. The quickest and simplest way to do all of this is through the iD Mobile app. Acting fast here will minimise any disruption and keep your account secure while you take the next steps.

 

Report the theft to the police.

 

 

If you’re confident your phone was stolen, you need to report it to the police. You’ll be given a crime reference number – which might be needed later for any insurance claims or if your network provider asks for proof of theft. You can usually file a report online or by calling 101, the non-emergency police number. 

Even if you’re not sure whether it was stolen or just lost, reporting it can be helpful. Especially if you find out fraudulent activity has been linked to your device. 

 

Secure your online accounts.

 

 

Your phone is more than just a gadget. Most of us have our whole digital life on there. That’s why it’s crucial to secure your online accounts as soon as possible. Start by changing the passwords on your email, banking apps, social media, and any other sites or services you use on the reg.

Switch on two-factor authentication (2FA) when you can as well. This adds an extra layer of protection by requiring a second form of verification, like a code sent to your email or another device. If your phone supports biometric login (like fingerprint or face recognition), that’s great – but don’t rely on it alone. Oh, and avoid reusing passwords too. If someone guesses it, they could get access to all your other accounts too!

 

Check your insurance or protection plan.

 

 

If you’ve got phone insurance, now’s the time to dig out the details. You might also be covered through your bank, network provider, or the retailer where you bought your phone – like Currys. Check what’s included in your policy too. Does it cover theft, loss or accidental damage? What’s the process like for making a claim? It’s all worth finding out. 

You’ll likely need your crime reference number and proof of purchase, so get those docs together early. If you’re not covered, think about getting protection for the future. It can save you a lot of stress – and money – if something goes wrong again. 

 

Prevent future issues.

 

 

Once you’ve dealt with the immediate situation, you’ll want to take some steps to protect yourself going forward. Start by using biometric security features like fingerprint or face recognition and make sure your PIN is strong and not easy to guess. It almost goes without saying, but don’t use 1, 2, 3, 4, 5 or your birthday! 

Avoid storing sensitive info, like banking details or passwords, in plain text on your phone’s notes app. Instead, use secure apps or password managers. And keep a record of your phone’s IMEI number (you’ll find it on the box or in your device settings), as this’ll help with tracking and reporting. Finally, don’t forget to back up your data regularly to the cloud. That way, you can restore it easily if your phone gets lost again. 

 

Restore and reconnect.

 

 

Once you’ve secured your accounts and sorted your SIM, it’s time to get back online. Order a replacement SIM or device through iD Mobile and restore any important data from your cloud backups. Whether you use Google Drive or iCloud, having your photos, contacts and apps backed up means you won’t lose everything. 

Then reinstall your apps, log back in securely and take a few minutes to go over your security settings. If you need some help, head to the iD Mobile Help Hub – it’s packed with handy guides and support.

Too many of your suggestions for after losing the phone, need the phone to sort e.g. Banking apps, iD mobile app. That is the trickiest part, especially when away from home. Any workarounds?

Agree with Sally question.  How do you do these steps without a phone

Log into ID with a browser either on a computer or someone else's phone.

This is NOT helpful.   How can you access “find my iphone” if you don’t have another device with you?   How can you log on to the ID app if you no longer have a phone and are travelling alone?    How do you manage when all your finance products etc insist on using 2 factor authentication via your phone and the phone has gone?  
A list of phone numbers or emails to contact would be much more useful.

“A list of phone numbers or emails to contact would be much more useful.”, And please, pray tell me how you’re going to use this information if you, quote, “ How can you access “find my iphone” if you don’t have another device with you? “. I really hope you do not lose your device, as I'm sure you might possibly explode.

Rusto, my comment related to the main article, not your comment.  I apologise if you thought otherwise, but there was no need for you to be so rude.  I stand by my original statement that the article is unhelpful.  For example rather than suggesting to use an app you won’t be able to access it could have said “make sure you know your ID password so you can log on to your ID account from any device” and “make sure you still know how to log on to your other accounts without relying on using face id on your phone”.


  • August 29, 2025

This is all very useful if you have a family member you can share ‘find my devices’ with. Otherwise I agree with the comments, you will have difficulty. Otherwise the article is useful

If your phone is lost or stolen how can you use Find my Phone?  The same goes for using the ID Mobile app as I would need my phone to use it.  Have you thought your solutions through or am I missing something?

It seems the ID adviser is ignorant of SIM Pins.  Set a SIM pin on your phone and if it’s stolen they can’t put it in another phone and access your data.

Apologies ​@Digger Dogs, you’re correct a SIM pin is a great security measure. We have a dedicated article here:

With more information. Thanks!

It seems the ID adviser is ignorant of SIM Pins.  Set a SIM pin on your phone and if it’s stolen they can’t put it in another phone and access your data.

As long as you have good controls on your plan I would actually recommend not using a SIM PIN. 

The remote lock and remote erase features on an iPhone are only successful with an internet connection, if the phone loses its battery or is turned off and back on then it can’t connect to the internet without the PIN which means there is no chance of a remote erase.

You want the best chance for a remote erase if the phone is turned back on so I wouldn’t use a SIM PIN. Not all thieves will use a cage to block the phone’s signal. Also what if your phone is just lost and it has no battery, if a nice stranger tries to help and turn it on they won’t be able to see the “lost message” you can set up or receive any calls on it from you. Another tip is to use eSIMs only where possible, then it cannot even be removed.

With that in my mind I would not cancel that mobile number/ID connection for a day or two at least.

You should already keep the default setting enabled that ensures the contents of your notifications/messages are not shown when your phone is locked to avoid the thief viewing One-Time-Passcodes.

Using a strong passcode to unlock your device not a 6 digit number, an actual password, to avoid anyone memorising it when they are watching you. It’s not a hassle as we should all be using biometrics to unlock our phones in public anyway, but for the times we don’t then a 6 digit number is just not good enough. FaceID can be enabled to unlock any apps that contain sensitive information because who wants a thief to know your address - all photos have a location attached  for example. So enable FaceID to access apps such as email, messages, notes, photos, Uber, bike rental apps, Google maps - likely contains your home address and search history but you can turn that off.

Hi Sally I had this situation in Brazil. It’s important to have one bank account with money in that you can access without that mobile number and that still offers online banking without an app. You also need a way to contact organisations, banks and people back at home in an emergency and relying on a hotel or strangers to use their phones is not straightforward - both of these options didn’t work for me as they couldn’t make calls abroad to the UK. Luckily I had some credit on Skype to make the necessary calls from a laptop, Skype doesn’t offer this any more but there are alternatives. Just imagine you are stranded with no phone and no contact numbers - you need to have these saved securely somewhere online so that you can access them when you have found another computer/phone to use safely and if it’s not yours then always use private browsing and close it when you’re finished.

Yes and having emergency funds in a bank that uses your voice as a password for telephone banking is useful in emergency as you may not remember all your passwords.

The article about losing your ‘phone is interesting. But, if you lose your ‘phone how do you locate it?  Will an Apple ‘phone locate an Android ‘phone and vice versa? I am not being stupid, or am I. I only have one ‘phone and it is stolen I am stuck unless I buy a new ‘phone and then use that to disconnect my ‘phone.

You can use any make of phone or computer that has internet. It could belong to you, someone you know or a stranger. Then you can attempt to locate, remote lock and remote erase the iPhone or Android. You just need your Apple or Google login details the lost/stolen device was registered with.

Thanks for this info.

How do we go about getting the IMEI number from Customer Service? I have a SIM only plan for you. my Insurance is asking for the IMEI but we no longer have the box.
I have spoke with Customer Service, first guy ended the chat as he couldn't process what I was asking for. 2nd Rep a little better but no idea if i am actually going to get it or not, she has requested the back office help.
