Frequently Asked Questions

eSIM technology is a modern digital alternative to traditional SIM cards. Instead of inserting a physical SIM card into your device, a mobile network profile can be installed digitally.

An eSIM profile is the digital equivalent of a SIM card. It contains the information needed to connect your device to a mobile network and can be downloaded to your device over the internet.

• Multiple profiles on one device.

  A device can store many eSIM profiles (often dozens), instead of being limited to one or two physical SIM cards.

• Instant activation.

  eSIM profiles can be downloaded directly to your device via the internet, so there’s no need for shipping or physical delivery.

• Global carrier support.

  A large number of mobile operators around the world now provide voice and data services using eSIM technology.

• High level of security.

  The global infrastructure certified by GSMA provides a very high level of security for eSIM connectivity.

The eSIM.box card is a special SIM card that enables your mobile device to work with eSIM technology.

• Android

  Full compatibility. You can install new eSIM profiles and manage them directly on the device.

• iOS

  Partial compatibility. You cannot install new eSIM profiles using QR codes, but you can manage preinstalled eSIM profiles through SIM Applications / SIM menu and use them like a regular SIM card.

• Other devices (including M2M and IoT)

  Devices such as M2M and IoT equipment can use the eSIM.box card with preinstalled eSIM profiles in the same way they would use a regular SIM card.

• PRO version

  The memory capacity for profiles is approximately 460 KB. Depending on the size of each profile, the card can store around 10–30 eSIM profiles.

• LITE version

  Supports up to 2 eSIM profiles.

Even if your device supports eSIM, most carriers link each eSIM profile to a single device, making it difficult to use the same profile across multiple devices.

The eSIM.box card solves this by storing eSIM profiles on a physical card. This allows you to move your profile between devices — simply by inserting the card — just like a regular SIM.
