FAQ
Got a question? We’ve got answers
What is eSIM technology?
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.
What is an eSIM profile?
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.
What are the benefits of eSIM technology?
A device can store many eSIM profiles (often dozens), instead of being limited to one or two physical SIM cards.
eSIM profiles can be downloaded directly to your device via the internet, so there’s no need for shipping or physical delivery.
A large number of mobile operators around the world now provide voice and data services using eSIM technology.
The global infrastructure certified by GSMA provides a very high level of security for eSIM connectivity.
What is the eSIM.box card?
The eSIM.box card is a special SIM card that enables your mobile device to work with eSIM technology.
Which devices support the eSIM.box card?
Full compatibility. You can install new eSIM profiles and manage them directly on the device.
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.
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.
How many eSIM profiles can be stored on an eSIM.box card?
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.
Supports up to 2 eSIM profiles.
Why do I need an eSIM.box card if my device already has built-in eSIM?
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.
