Preventing Mobile Phone Theft – Essential Steps

To block your mobile device through the provider in case of an emergency, you’ll need the following information:

  • Mobile phone number.
  • SIM card number.
  • Customer number/password.

Note down your card number by removing the SIM card from the phone—ideally before first use. Keeping this information readily accessible will prepare you for emergencies.

Additionally, if you’ve noted your landline number or email address on your mobile phone and it gets lost, an honest finder might contact you. Many smartphones allow you to save a message via settings, which is displayed even when the screen is locked.

Find out and note the IMEI number

Every mobile phone can be identified by its 15-digit IMEI (International Mobile Station Equipment Identity) number. If your smartphone is reported stolen to the police, they’ll need this IMEI number. You can find your mobile phone’s IMEI number by dialing *#06# on your phone. The IMEI will then appear on your screen. Note this number down and keep it safe. For some devices, the IMEI number is also found on the packaging or in the mobile phone contract.

Lock and Track Smartphones

Almost all smartphones can be located remotely and allow you to send messages to the device, erase data, or lock the device itself. Providers like Apple, Google, and Microsoft offer these options for their iOS, Android, and Windows operating systems, respectively, and often mobile phone manufacturers do as well. There are also additional apps from various providers that can perform these tasks and offer extra features, such as taking photos of the thief attempting to unlock the screen. It’s best to familiarize yourself with these options immediately after starting up your new device.

Regularly Back Up Data

Your smartphone stores a lot of personal data, from photos to contacts. To prevent loss if your mobile phone is stolen, regularly back up your data. Both operating systems and anti-theft apps can perform this function.

Use the Display Lock Function

Secure your smartphone with a PIN or pattern lock. Without this, if your smartphone is turned on, a thief can instantly access all your data and functions. The PIN or display lock also prevents the thief from using the device with a new SIM card.

Contact Information on the Cell Phone

Having a sticker with contact information inside the cell phone case or on the cell phone itself can be helpful.

Get a Replacement Cell Phone and Replacement Card

If your cell phone is gone, you can either buy a new device or use a used one. A subsidized device is typically only available if you sign a two-year contract when purchasing it. To be able to make calls again, you also need a new SIM card, which can be ordered from your network operator or provider. The costs for the replacement card vary depending on the provider. The term of an existing contract is not changed by purchasing a replacement card, and the telephone number remains the same.


Even prepaid cell phones should be blocked. With some providers, you might end up in debt.

Is Cell Phone Insurance Worth It?

Regular household insurance only covers if your cell phone is stolen during a break-in or robbery. If such an event occurs, it must always be reported to the police (with the IMEI number). Special cell phone insurance is usually only worthwhile for very high-quality devices. Ensure that the insurance cover is also valid abroad.
