Phone theft is becoming a worldwide issue. In London alone, a phone is reported stolen roughly every seven minutes, and snatch thefts on bikes and mopeds have very much contributed to these numbers. Theft is not just about losing the device. The criminals are after the contents: your banking applications, your accounts, and sufficient personal data to conduct identity theft. Securing your phone implies safeguarding the physical device as well as the data on it. Here is what you can do to secure both.

Why Phone Theft Is About More Than the Device

People usually think that losing a phone through theft just means the cost of buying a new one. However it may expose your bank accounts, emails, photos, and even lead to identity theft. Phone theft has escalated to a level where organized crime groups are involved in stealing devices in bulk and shipping them abroad; one unlocked phone can give access to multiple accounts.

The good news is that a brief preparation can make the thief's effort in utilizing your stolen phone almost useless. The actions described below are divided into two categories: preventing the theft from happening and lessening the harm if it does.

How Thieves Target You in Public

Most phone thefts happen because the thieves see an opportunity. By lowering how much you expose yourself, you can drastically reduce your risk.

It's best to keep your phone hidden when you're not using it. A phone left on a cafe table or one visible in the back pocket is the easiest possible target to a thief, who can snatch it in mere seconds.

Look out for who's nearby when you unlock your phone. "Shoulder surfing" is when a thief watches or records you while you type your PIN, then steals the phone knowing they can open it. To avoid this, use Face ID or fingerprint instead of typing PIN when you are in public where other people can see.

They say never to give your phone to a stranger. A popular ploy is to ask to borrow it for a call or to "add their number." Once it's in their hands, it's gone.

Lock Your Phone Properly

Your lock screen is the first line of defense.

Biometric authentication (Face ID or fingerprint) combined with a strong passcode is the recommended way. A short four-digit PIN isn't sufficient. A longer alphanumeric passcode is very difficult to shoulder-surf or guess.

Configure your auto-lock to the shortest time that you find comfortable so the phone locks itself quickly when you leave it.

Disable message previews on the lock screen. If previews are enabled, a thief will be able to see login codes, banking alerts and reset links without unlocking the phone. Changing this one setting will fix a major vulnerability.

Turn On Built-In Anti-Theft Protection

Both main platforms come equipped with standalone anti-theft features. Nearly all people never activate them.

iPhone: Enable the Stolen Device Protection feature. This prevents a thief from changing your main security settings, even if they have your passcode, when the phone is in an unfamiliar location. Also, you can make apps with sensitive information inaccessible without Face ID by simply pressing and holding the app, then selecting 'hide' and 'require Face ID'.

Android: Enable the Theft Detection Lock feature which relies on the phone's motion sensors to detect if the device has been snatched from your hand and automatically locks it. In addition, you may be able to place banking and wallet apps in a secure or private folder that is protected by a separate passcode.

Protect Your High-Value Apps

Locking the phone itself is not sufficient. Put a second level of security on whatever is really important.

Secure banking apps and digital wallets with biometrics or a strong unique password. Never use a password that you also use for other purposes, and never store passwords in a plain notes file on the phone - this is the first spot a thief will look at.

Think about if the most private apps should be on your regular phone at all. Banking apps which you do not use very often could better be kept on a tablet that stays at home.

Record Your IMEI Number Now

Every phone has a unique IMEI number that can identify it if lost or stolen. Find yours by typing *#06# into the phone's keypad. Write it down and store it somewhere that isn't your phone, because you'll need it when reporting the theft and asking your provider to block the device.

Keep Backups and Recovery Access

What if your phone disappears; how will you access your account?

First of all, do a complete backup of your phone at regular intervals to avoid losing your data with the device. Secondly, be sure you have alternate means to receive your two-step verification codes, not only on the very phone that could be stolen. Also, always keep essential telephone numbers and recovery information in a location different from your phone.

Should you have photographs of your ID documents like passport or driver's license, securing them by way of a password or keeping them in a safe folder is a must since thieves can use these documents fraudulently to get credit in your name.

Keep Your Software Updated

Security patches close the gaps thieves and fraudsters rely on. Turn on automatic updates for both your operating system and your apps so you're always on the latest protections.

What to Do If Your Phone Is Stolen

The sooner you respond, the better.

Make a police report. Dial your local emergency number if you are injured, feeling unsafe or the theft is still happening. If not, use your country's non-emergency police reporting line or online reporting service. Provide them your IMEI number and details of any unauthorized transactions.

From another device:

• Lock the phone remotely using Lost Mode (iPhone) or Find My Device / Remote Lock (Android), and locate it if you can before the thief disables tracking.
• Contact your bank and any financial providers to freeze the accounts and cards linked to the phone.
• Change passwords for your email first, then social media and banking, and force a logout of all sessions.
• Tell your mobile provider so they can block the device by IMEI and stop verification codes being sent to your number.

Watch for Fraud Afterwards

Keep an eye on your accounts for transactions you didn't make or sign-in alerts you don't recognize. Alert your bank immediately if anything looks wrong. Transactions made after you've reported the phone stolen may be covered by your bank.

Phone Theft Protection FAQ

How do I protect my phone from theft?

Keep it out of sight in public, lock it with biometrics and a strong passcode, turn off lock-screen message previews, and switch on your phone's built-in anti-theft protection. Then back up your data and note your IMEI number so you're prepared if it is taken.

What is the best way to protect my phone from thieves?

There's no single setting. The strongest protection combines physical awareness in public with software protection: Stolen Device Protection on iPhone or Theft Detection Lock on Android, biometric locks on sensitive apps, and message previews turned off.

How do I protect myself against smartphone theft and fraud?

Stop the data being useful. Lock high-value apps behind separate biometrics, never store passwords in plain notes, hide photos of ID documents, and turn off lock-screen previews so login codes can't be read. If the phone is stolen, lock it remotely and contact your bank fast.

What should I do first if my phone is stolen?

Lock it remotely from another device, then change your email password and contact your bank. Report it to the police with your IMEI number, and tell your mobile provider so they can block the device.

Can someone access my bank if they steal my phone?

Only if your banking apps aren't properly secured. With biometric locks, no stored passwords, and message previews off, a thief can't easily get in even with the device in hand.

How do I find my phone's IMEI number?

Type *#06# into your phone's keypad and it will display instantly. Save it somewhere other than the phone itself.
