Network redundancy

EMnify SIMs work with multiple carriers within a country and auto-select the best network. If the device enters a region with poor coverage, the SIM automatically switches to an available carrier to maximize uptime.

Switch carriers over-the-air with eUICC

The global eUICC standard allows you to manage carrier subscriptions of IoT devices without the need to physically change SIM cards.

How eUICC SIMs can benefit your IoT deployment:

  • Remote profile provisioning and management

    Easily provision and load new operator subscriptions over-the-air to your remote, hard-to-access devices.

  • Avoid permanent roaming

    Select local carriers to comply with permanent roaming restrictions.

  • Reduce costs

    Seamlessly switch between available carriers to get the best rates on connectivity.
