What To Do if Your Phone is Stolen? Here’s What I Learned (the Hard Way)

I’ll keep this short: a few weeks ago, I left my shiny S24 Ultra in a taxi. What followed was honestly one of the worst weeks I’ve had in a long time. Not because of the phone itself (although that stung), but because of everything attached to it. My emails, my bank, my photos, my work apps. All of it, suddenly in someone else’s pocket.

Calling support was the first battle, which I had to do though my laptop. After reaching support, they said that the taxi driver claimed he didn’t see anything (an outright lie). Within a week, I had verification codes coming to my WhatsApp account in Chinese. Thankfully, I’d already taken all of the necessary steps to protect myself.

I made a fair few mistakes along the way, so I wanted to write this up properly. If your phone’s ever stolen, or if you’ve just lost your phone and you’re scrambling to figure out what to do next, this should help.

First Things First: Try to Track It

Your best window is the first few minutes. Thieves know this too, which is why they tend to switch phones off or pull the SIM out pretty quickly.

If you’ve got access to another device (a mate’s phone, a laptop, whatever), try to locate your phone straight away.

• iPhone users: head to iCloud.com/find or open the Find My app on another Apple device.
• Android users: go to google.com/android/find and log into your Google account.

If the phone’s still on and connected to the internet, you might be able to see where it is. You can also lock it remotely or stick a message on the screen. One thing though: please don’t go chasing after it yourself. People have been hurt doing that. Note the location down and pass it on to the police.

Turn On Lost Mode

Both Apple and Google let you put your phone into a Lost Mode remotely. This locks the screen, kills Apple Pay or Google Pay, and blocks access to your data. I got mine into Lost Mode roughly 20 minutes after it was taken. Looking back, I wish I’d done it sooner. If you can do it within five minutes, do it within five minutes.

Report It!

Go to the Police

I went to my local station that evening. Honestly, I wasn’t expecting much, and they were upfront that recovery is unlikely. But filing a report gives you a crime reference number, and you’ll need that. Insurance companies ask for it, and some carriers want it too before they’ll block your device.

Ring Your Carrier and Get the IMEI Blocked

This is a big one. Ring your mobile provider as soon as you can and tell them your phone’s been stolen. Ask them to block the IMEI. For anyone who doesn’t know, the IMEI is basically your phone’s unique ID number. Once it’s blocked, the handset can’t connect to any mobile network, even if someone sticks a different SIM card in it.

Here’s something I didn’t know at the time: if your phone supports two SIM cards (and a lot of newer phones do), it’ll actually have two separate IMEI numbers. You need to give your carrier both of them. You can usually find your IMEIs on the original box, on your online account with your provider, or on a previous bill. Write them down somewhere safe that isn’t your phone. I’ve got mine saved in a note at home now.

While you’re on the phone to your carrier, get them to cancel your SIM card as well. That stops anyone making calls, sending texts, or burning through your data. Looking for a new SIM? Shop our selection of business SIM only plans here.

Secure Your Accounts

Right, this is where it gets tedious but it’s absolutely essential. Think about how many apps you were logged into on your phone. Email, social media, banking, shopping, cloud storage. Every one of those accounts is now at risk.

Change Your Passwords

Start with the important stuff and work down:

1. Email (Gmail, Outlook, whatever you use). This is the big one, because email is how you reset passwords on everything else.
2. Banking and finance apps.
3. Social media: Instagram, Facebook, X/Twitter, TikTok.
4. Shopping accounts like Amazon and eBay, especially if you’ve got card details saved.
5. Cloud storage: Google Drive, iCloud, Dropbox.
6. Anything work-related.

Do all of this from a computer or a borrowed device. And use proper strong passwords, not variations of your old ones.

Sign Out of Every Device

Here’s the bit that caught me out: changing your password doesn’t always boot someone off your account. Loads of services keep sessions active even after a password change. So you need to go in and manually kick out all devices. The main ones to sort out are:

Google (Gmail, YouTube, Drive, etc.):

Go to myaccount.google.com, then Security > Your devices > Manage all devices. Find the stolen phone and hit “Sign out.”

Also worth checking Security > Recent security activity to see if anyone’s been poking around.

Meta (Facebook and Instagram):

On Facebook, go to Settings & Privacy > Settings > Security and Login > Where You’re Logged In. Hit “Log out of all sessions.”

For Instagram, it’s Settings > Security > Login Activity, then remove anything that looks wrong. Both can be done from a desktop browser.

Then go through everything else you can think of. X/Twitter, LinkedIn, Spotify, Netflix, Amazon. If you were logged in on your phone, assume you need to sign out remotely.

The 2FA Problem (This Was a Nightmare)

Alright, so this bit nearly broke me. Two-factor authentication, or 2FA, is brilliant for security. Until your phone gets nicked and you realise half your accounts rely on it to let you in.

Most of my accounts were set up to send a verification code by text. No phone, no SIM, no text. Which meant no code. Which meant I was completely locked out.

Google’s Verification Loop

Google was the worst by a mile. I tried logging into my account from my laptop, and it asked me to verify my identity. Fair enough. Except the only option it gave me was to send a code to my phone number. The phone number I no longer had access to.

There was no “try another method” button that actually worked. Every time I clicked it, all of the options were still mobile only. No prompt for a backup email. No recovery code option. Just the same screen, over and over, telling me to check my phone. I genuinely spent hours going round in circles trying to find another way in.

In the end? There wasn’t one. I had to wait for my carrier to send me a replacement SIM with my old number on it, which took the best part of a week. Nearly six full days without access to Gmail, Google Drive, Google Photos, or anything connected to my Google account. It was honestly maddening.

How to Stop This Happening to You

Please learn from my mistake here. Go and do this today:

• Switch your 2FA to an authenticator app (Google Authenticator, Microsoft Authenticator, or Authy all work) instead of relying on text messages.
• Print out or write down your backup recovery codes and keep them somewhere safe at home. Not on your phone. Not in your email.
• Add a backup email address to your accounts so you’ve got another way to verify yourself.
• If you want to go a step further, look into hardware security keys like a YubiKey for your most important accounts.
• Check your 2FA settings on all your main accounts. Seriously, do it now while you’re thinking about it.

Banking and Finances

My stomach dropped when I thought about my banking apps. If you’ve got any kind of financial app on your phone, or card details saved anywhere, you need to sort this out fast.

How to Block Your Bank Account When Your Phone Is Stolen

• Ring your bank’s fraud line straight away. Every major bank has a 24/7 number for this. Tell them your phone’s been stolen and ask them to freeze any cards that were connected to mobile payments or saved on the device.
• Apple Pay, Google Pay, and Samsung Pay should deactivate when you turn on Lost Mode or do a remote wipe. But don’t just assume this has worked. Call the bank and double-check.
• Go through your recent transactions carefully. Thieves can sometimes tap for contactless payments in the minutes before you manage to lock everything down.
• Don’t forget other financial apps either: PayPal, Revolut, Monzo, any investment apps, crypto wallets. Get in touch with each one and lock your account.

I got lucky. My banking app needed Face ID to open, so nobody got in. But I’ve heard plenty of stories where people weren’t so fortunate. Don’t leave it to chance.

Sensitive Data: What Else Was on There?

This is the one that really kept me up at night. Have a think about what photos you’ve got saved on your phone. Specifically: have you ever taken a picture of your bank card? Your passport? Your driving licence?

I had. There was a photo of my passport in my camera roll from when I’d booked a holiday, and a snap of my driving licence from a flat rental application a while back. Both now potentially sitting on a stolen phone.

If you’re in the same boat:

• Get on to your bank and ask for a new card with a new number.
• If your passport photo’s been compromised, ring the Passport Office and find out if you need a replacement.
• Report any compromised ID documents to Action Fraud (if you’re in the UK).
• Keep a close eye on your credit report for the next few months. Experian and ClearScore both let you do this for free and they’ll alert you to anything dodgy.

Identity theft is one of those things you think won’t happen to you. But all it takes is a photo of the right document in the wrong hands.

What Do Thieves Do With Stolen Phones?

I spent a lot of time wondering about this afterwards. It actually helped me understand why each step above matters so much.

Most phone thieves aren’t criminal masterminds sitting in a dark room trying to hack your email. The reality is a bit more mundane:

• Quick resale is the most common one. Stolen phones get sold within hours, either to dodgy second-hand shops, through online marketplaces, or shipped abroad to countries where the IMEI blocklist doesn’t reach.
• Parts. Even a locked phone has a screen, a battery, camera modules, and other bits that are worth money individually.
• Some will try a factory reset to wipe the phone and set it up fresh. iPhones with Activation Lock make this really difficult, but older phones or Android devices without proper security features can be more vulnerable.
• In some cases, especially more targeted thefts, criminals will try to get into your accounts, intercept 2FA codes (particularly if they’ve kept your SIM), make purchases, or steal personal information for identity fraud.
• For most models, a skilled thief can replace the motherboard of your device and gain full access to your phone, whilst keeping the existing data.

That’s why blocking the IMEI and wiping the phone remotely matters so much. And it’s why locking down your accounts isn’t optional. You’re not just protecting a handset. You’re protecting everything that’s connected to it.

What I’m Doing Differently Now

Going through all of this has properly changed how I think about my phone. Here’s what I’ve sorted out since:

Offline Tracking

This is the single biggest thing I’d recommend. On iPhone, it’s part of Apple’s Find My network. It uses Bluetooth signals from other nearby Apple devices to locate your phone even when it’s not connected to Wi-Fi or mobile data. Android has something similar through Google’s Find My Device network. So even if a thief turns the data off, there’s still a decent chance of tracking the phone.

Everything Else I’ve Changed

• Both my IMEI numbers are written down and stored at home, nowhere near my phone.
• All my 2FA is now through an authenticator app, and the backup codes are printed out and kept in a drawer.
• I’ve deleted every photo of a sensitive document from my phone and my cloud storage.
• My passcode is now a proper alphanumeric one, not a four-digit PIN.
• Every banking and finance app on my phone requires Face ID or fingerprint to open.
• I’ve finally got mobile phone insurance that actually covers theft.
• I’ve turned on Stolen Device Protection (it’s available on newer iPhones) which adds extra security when your phone’s in an unfamiliar location.

Get Insurance. Seriously.

I’ll hold my hands up: I didn’t have insurance when this happened. Replacing the phone cost me a painful amount of money and the whole thing could’ve been so much easier if I’d been covered. If you’re reading this without insurance, sort it out. It’s only a few quid a month and most policies cover theft, accidental damage, and loss. Some business mobile contracts come with insurance included, so it’s worth checking with your provider.

Quick Checklist: What to Do If Your Phone Is Stolen

• Track your phone using Find My iPhone or Google Find My Device. Turn on Lost Mode immediately.
• Report it to the police and get yourself a crime reference number.
• Call your carrier. Get both IMEIs blocked (if it’s a dual SIM phone) and cancel your SIM card.
• Change all your passwords. Email and banking first, then everything else.
• Sign out of all devices and end active sessions on Google, Meta, and every other platform.
• Sort out 2FA. If you’re locked out, contact providers directly. Get a replacement SIM with your old number as fast as you can.
• Ring your bank. Freeze cards, check for dodgy transactions, and make sure mobile payments are disabled.
• Think about sensitive data. Replace any cards, documents, or IDs that might be compromised.
• Tighten up your security going forward. Enable offline tracking, switch to an authenticator app, delete sensitive photos, and get yourself insured.

Look, having my phone stolen was rubbish. There’s no sugarcoating it. But it did force me to actually sit down and think about how much of my life runs through that one little device, and how completely unprepared I was to deal with losing it.

If this article helps even one person avoid the panic and scramble I went through, then it was worth writing. And if nothing else, please just take five minutes today to check your security settings. Future you will be grateful.
