Can You Track a Phone with an eSIM if it’s Turned Off? Reality vs. Current Technology

Losing or having a smartphone stolen is one of the biggest concerns for mobile users. With the advent of eSIM technology, a recurring question has emerged: is it possible to track a phone with an eSIM if it is turned off?

Unlike physical cards that can be removed to disconnect the terminal from the network, the eSIM remains integrated. However, the device’s power state plays a crucial role. In this article, we analyze current localization capabilities and how eSIM technology improves your chances of recovery alongside MyRoamUp experts.

The Myth and Reality of Geolocation Without Power

Traditionally, if a mobile phone was turned off, the GPS signal and data connection were interrupted, making real-time tracking impossible. However, the architecture of modern devices has changed the rules.

• The Role of the eSIM in Tracking: The eSIM is fundamental here for one physical security reason: it cannot be removed. While a thief usually extracts a physical SIM immediately to prevent tracking via cell towers, a MyRoamUp eSIM remains tied to the hardware. This forces the attacker to keep the device in a state where, if it turns on or enters reserve mode, the terminal’s identity remains traceable.

• “Find My” Technology and Power Reserve: Both Apple and Google have implemented systems that allow certain hardware components to remain in a low-power state even when the phone appears to be off. This allows the device to emit secure Bluetooth signals that can be detected by other nearby devices in the same network (Apple’s “Find My” or Google’s “Find My Device”).

How to Track a Device by Operating System

The ability to track a phone with an eSIM turned off depends directly on the model and the installed software.

• Android: Google has updated its “Find My Device” network. On recent models (like the Pixel series or high-end Samsung Galaxy), it is possible to locate the terminal while off because the radio frequency chip keeps a beacon active. eSIM integration makes it easier for the operator and the user to maintain control of the ICCID at all times.

• iPhone (iOS): Since iOS 15, iPhones can be located for up to 24 hours after running out of battery or even if they have been manually turned off. The eSIM ensures that as soon as the device receives a minimal signal, security protocols activate without the risk of the line being physically tampered with.

Anti-Theft Security (SIM vs. eSIM)

Current Limitations of “Off” Tracking

It is important to be realistic. Although technology has advanced, barriers still exist:

• Total Battery Depletion: Once the critical power reserve is exhausted (after several days), the hardware will not be able to emit any signal.
• Faraday Cages: If the mobile is kept in a metal box that blocks electromagnetic waves, tracking will be impossible.
• Zero-Coverage Zones: The system relies on other mobiles passing nearby to anonymously report the location.

MyRoamUp Tips to Maximize Security

To ensure you can track your phone with an eSIM under any circumstance, we recommend:

1. Always activate the offline search network: Check your iPhone or Android settings to ensure the “Participate in the Find My network” option is active.
2. Maintain a robust screen PIN: This prevents a thief from accessing settings to disable Bluetooth or Airplane Mode.
3. Register your IMEI and eID: Always have the identifiers for your MyRoamUp eSIM handy. In case of a police report, this data is vital for authorities.
