Frequently Asked Questions

  • A physical eSIM functions like a standard eSIM chip embedded in a device. However, it is designed to fit into a traditional SIM card slot. This allows devices without built-in eSIM hardware to benefit from the flexibility of eSIM technology. With a physical eSIM, users can remotely download and manage multiple carrier profiles, enabling seamless switching between cellular providers without the need to physically swap SIM cards.

  • Using a physical eSIM provides several benefits:

    • Flexibility: Easily switch between cellular providers without physically replacing SIM cards.
    • Convenience: Remotely download and manage multiple profiles for personal, business, or travel use.
    • Compatibility: Allows older devices with standard SIM slots to access eSIM functionality.
    • Eco-Friendly: Reduces the need for physical SIM card production and waste.

  • Physical eSIMs are designed to fit into standard SIM card slots, so they can be used on most devices that support a traditional SIM card. However, for the eSIM functionality to work, your device must support Android or Linux eSIM profile manager (next FAQ entry).

  • The eSIM profile manager is a lightweight application designed to manage eSIM profiles, including downloading, activating, and deleting profiles. Below are the key requirements:

    For Android devices:
    • Most phones or tablets with Android 9 or later version.
    For Linux devices:
    • Operating System: e.g. Debian, Ubuntu, Raspberry Pi OS (RPiOS), and OpenWrt (v22.03.0 or higher).
    • Hardware: A Linux-compatible device such as a Raspberry Pi, PC, or embedded system with network connectivity and LTE/5G module
    • Access to eSIM: The app uses LTE/5G module to access to physical eSIM.
    It is possible to port the app to a different OS, please contact us for more info.

  • Removing a physical eSIM will temporarily disable the cellular profiles stored on it, as they require the physical card to remain inserted in the device. If you reinsert the physical eSIM, the profiles should become active again. However, if you switch to another SIM or physical eSIM, you may need to reconfigure your device's cellular settings.

  • Yes, a physical eSIM can be reused as long as it has storage capacity for new profiles. You can delete old profiles and provision new ones through supported carriers. However, the exact number of profiles that can be stored simultaneously depends on the eSIM's capacity and the device's software.
