No traditional roaming — low-latency network worldwide

EMnify's communication platform is distributed across multiple geographical regions. That means data does not travel across oceans to an operator's home network. Instead, it's broken out locally. You can either control the data's destination or our system will choose the closest region to the SIM card.

  • Ensures that your customers' data stays local
  • Reduces data latency by up to 600ms
  • Consumes less power with shorter transmission time

Global network access with a single SIM

Avoid complex contract management, lengthy operator negotiations, and complicated SIM logistics. EMnify SIMs operate worldwide, simplifying large-scale, global SIM management.



Connect your device to the best available network at its location.



Get the same tariff for global coverage with a single SIM.



Connect via 2G, 3G, 4G, LTE-M, or NB-IoT based on your IoT use case.

Built-in fallback to ensure the best service availability

We know you run business-critical solutions. Our multi-layer redundancy architecture provides 99.99% network uptime — guaranteed.

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.

Infrastructure redundancy

Our platform is deployed to the cloud in multiple availability zones and regions. Even if one data center fails, your device communication remains uninterrupted.

IMSI redundancy

Unlike other mobile services that rely on a single home network, EMnify service is backed by multiple IMSI sponsors. When one home network is down, our SIMs fall back to another IMSI, minimizing connectivity loss.

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.
