Unlike a traditional SIM, an IoT SIM card is designed to send and receive data rather than enable voice calls. With more memory and durability than their consumer counterparts, IoT SIM cards also last longer—up to 10 years or more. They’re able to withstand environmental challenges like vibration, corrosion, and extreme temperatures.

An IoT SIM card contains a contact chip encased in plastic. The chip stores distinctive information about the device, such as credentials and carrier data, and links the device to the network. IoT SIM cards are able to operate more independently than consumer SIMs. Unlike traditional SIMs, they don’t need human interaction on the device side to be activated. Some IoT SIMs can be provisioned remotely with eUICC (embedded universal integrated circuit card) technology.

It depends on the card. Hologram's SIM cards are global and able to connect to the best networks available, anywhere in the world.

eUICC stands for embedded universal integrated circuit card. This is the technology that allows a SIM card to enable more than one subscriber profile over its lifecycle. (Carrier “subscriber profiles” indicate that a device has an account and can work on their network.) If your SIM card is eUICC-enabled, you can switch between cellular carrier profiles without ever needing to physically swap out the SIM card.

eUICC is the software that makes this possible. But for eUICC to work, you must use the right hardware — in this case, an eUICC SIM card that can support all the necessary profile management operations and additional memory.

Basically, eUICC SIMs act as a digital wallet that lets you use several different “credit cards” (or subscriber profiles), all on the same eUICC SIM card.

SGP.32 is the newer GSMA standard for remote SIM management, designed specifically for IoT deployments. Where the earlier SGP.02 standard relies on a push-based model, SGP.32 uses a pull-based architecture — meaning the SIM initiates profile updates rather than waiting to receive them. This makes large-scale profile operations more reliable, particularly in environments with intermittent connectivity. Hologram's SGP.32 Hyper SIMs are now available in limited quantities.

SGP.02 is the original GSMA standard for M2M remote SIM provisioning. It uses a push-based model where a central subscription manager initiates profile operations. Well-established and widely deployed, SGP.02 is the right choice for fleets with consistent connectivity or teams expanding an existing M2M deployment. Hologram Hyper SIMs support SGP.02, and Conductor handles SGP.02 profile lifecycle management alongside SGP.32 in mixed fleets.

Conductor is Hologram's SIM orchestration software. It works with Hologram Hyper SIMs to automate profile lifecycle management, define failover rules, and recover connectivity without physical device access across fleets of any size. SGP.32 Hyper SIMs unlock Conductor's full feature set.

The eSIM is the hardware component, and the eUICC is the software component or operating system that allows for over the air (OTA) profile updates. An eSIM is ideal for IoT devices that may be exposed to harsh conditions because it can be soldered directly to the board and vacuum sealed to minimize exposure. This soldering also allows for smaller form factors with fewer pieces. If you are developing a device that needs to last, an eUICC-compatible eSIM can ensure long-term usability. Our embedded SIMs (eSIMs) are available in MFF2 (DFN8) formats.

IoT SIM cards come in all the traditional form factors: 2FF, 3FF, and 4FF. You can also choose MFF2 if you want the SIM to be embedded in your device and to include over the air (OTA) provisioning capabilities.

Every Hyper SIM includes powerful security features like Private APN, fraud detection, and device locking.
