How does Hologram use eUICC?

Hologram SIMs use eUICC to enable global connectivity coverage and perform over-the-air updates to your devices. eUICC on a SIM acts as a sort of digital wallet that lets you use several different “credit cards” (or subscription profiles), all on the same eUICC SIM card. One eUICC SIM can switch between different profiles to adjust connectivity instead of having to physically remove one SIM with one profile for a different SIM with a different profile.

Hologram developed Hyper, our eUICC offering, to give M2M users more flexibility with their devices. Hologram handles all the technical integrations so that companies can use eUICC-enabled devices anywhere, with any of Hologram’s global carrier partners. This simplifies their supply chains and extends the life (and usefulness) of their devices.

Our Dual-Core SIMs extend eUICC capabilities even further, allowing your devices to switch profiles automatically if your SIM loses connectivity. You can read more about how our Dual-Core SIMs use network fallback to protect you from unexpected downtime here.

Note: If you’re interested in contractually guaranteed reliability through our Dual-Core SIMs, reach out to your Hologram Account Executive or contact our Sales team to learn how you can make outages a thing of the past.

Outside of these common SIM and module functions, no additional requirements are typically required for IoT devices to support eUICC capability.
