Frequently asked questions

What is an IoT SIM card?

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.

How do IoT SIM cards work?

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.

Are IoT SIM cards tied to a single carrier network?

It depends on the card. Hologram's SIM cards are capable of multi-network connectivity. That means your devices can connect to the best networks available, anywhere in the world.

What is eUICC?

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.

What’s the difference between eSIM and eUICC?

An eSIM is the embedded SIM card (the hardware itself) that supports eUICC (the software profile). eSIMs are actually available in multiple form factors, including 2FF, 3FF, 4FF, and MFF2. 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.

Which form factors do IoT SIM cards come in?

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.
