Multi-IMSI SIM:
One SIM.
Many Networks.

One global SIM that switches between local, regional, global and satellite IMSIs automatically, based on your rules.

The FLOLIVE® Multi-IMSI SIM changes network identity over the air when policy, compliance or coverage calls for it, so one SKU ships everywhere and stays legal everywhere.

What is a multi-IMSI SIM?

A multi-IMSI SIM is a SIM card that stores several International Mobile Subscriber Identities (IMSI), each one tied to a different mobile network operator. An applet on the SIM switches between those identities over the air, so a single device can attach to a local operator in one country and a different operator after it crosses a border, with no hardware swap and no new carrier contract.

The Flolive Multi-IMSI SIM applies that switching across the Flolive network of 600+ mobile networks and 15+ carrier partners, with 40+ local breakout locations that keep traffic in-region. Profiles change on rules you set: signal loss, geo-fence crossing, roaming duration, or cost.

What’s inside the Flolive Multi-IMSI SIM

  1. Smart SIM applet – Built in-house, so switching logic and security are controlled by Flolive rather than a third-party SIM vendor.
  2. Automatic profile switching. The applet changes IMSI on signal loss, geo-fence crossing or policy trigger, with no reboot and no device-side firmware.
  3. Local IMSIs in-country. Devices attach as local subscribers in markets that restrict permanent roaming, like Brazil, China, Turkey, Canada and South Africa.
  4. eUICC and SGP.32 support. Multiple IMSIs and remote SIM provisioning run together on the same card.
  5. Optional satellite fallback. Adds coverage where no terrestrial network reaches.

What Our Customers Are Saying

With MNOs, the further you go from the home country, the more expensive it gets. Global rollout becomes really challenging with a consistent price level and that’s what we needed to solve. That’s why we looked into MVNEs like floLIVE, to support global connectivity with local pricing through a multi-IMSI setup.
Jochem Koppes
Managing Director, Thingsdata
The ability to autonomously switch between carriers and IMSIs and the OTA (over-the-air) aspects are much simpler and easier managed than others we have used.
Anthony Protopsaltis
Principal, Velocity IoT
floLIVE connectivity management platform (CMP) can independently serve either enterprises, where we go directly with the Sparkle brand, or allow us to go to market with floLIVE white-labelled solution. We can go to a Tier-3 MNO, for example, and give them our IMSIs and a customized floLIVE platform and they can resell this to their own customers using their own brand, with their own look and feel and their own commercial rules.

Frequently Asked Questions

What is a Multi-IMSI SIM?

A multi-IMSI SIM is a SIM card that stores several International Mobile Subscriber Identities, each tied to a different mobile network operator, and switches between them over the air based on rules you define. One card can therefore attach to different operators in different countries without a hardware change.

Can one SIM SKU be used globally

Yes. The Flolive Multi-IMSI SIM ships as a single SKU and works across 190+ countries, so there is no need to hold regional SIM inventory or swap SIMs when a device is redeployed.

Can the Flolive Multi-IMSI SIM be white-labelled?

Yes. The Flolive Multi-IMSI SIM can be sold under a partner’s own brand, with the partner controlling self-service access, pricing and policy management through the Flolive Connectivity Management Platform.

Does the Flolive Multi-IMSI SIM work with eSIM and eUICC?

Yes. Flolive multi-IMSI technology is compatible with eSIM under SGP.32 and eUICC, so multiple IMSIs and remote SIM provisioning can run on the same card for fallback and compliance

Why use a multi-IMSI SIM instead of a roaming SIM?

A roaming SIM holds one identity and depends on roaming agreements, which many countries cap at around 90 days. A multi-IMSI SIM carries local identities and applies them in-country, which keeps devices legal in permanent-roaming markets and gives them a second identity to fall back on if an operator fails or bans the traffic.

What makes the Flolive multi-IMSI solution different?

The Flolive SIM applet, the mobile core and the connectivity management platform are all built and operated by Flolive rather than assembled from third-party components. Switching happens in real time against the Flolive core, which is what gives per-session visibility.

Is the Flolive Multi-IMSI SIM compliant with regional data and telecom regulations?

Yes. The Flolive Multi-IMSI SIM applies local IMSIs in-country to meet permanent roaming restrictions in markets such as Brazil, China, Turkey, Canada and South Africa, and supports data localisation for privacy regimes including GDPR and CCPA.

Which IoT devices and form factors does the Flolive Multi-IMSI SIM support?

The Flolive Multi-IMSI SIM works with most cellular IoT modules and ships in plastic SIM (2FF, 3FF, 4FF), MFF2 solderable, iSIM and softSIM form factors. No custom device firmware is required.

Does a multi-IMSI SIM need a special device or module?

No. A multi-IMSI SIM presents as a standard SIM to the modem, so it works with off-the-shelf cellular IoT modules and needs no custom firmware.
