Update SIM profiles over the air
With Hyper eUICC SIM cards, cellular profiles can be remotely swapped so you never have to touch hardware or replace SIMs. SGP.32 Hyper SIMs bring next-generation remote profile management to fleets that need more control at scale. Pair with Conductor to automate profile switches, define failover rules, and audit every change across the fleet.
Meet Conductor
The industry’s first truly outage-proof connectivity
Hologram's Hyper SIMs include Outage Protection, which detects carrier outage events and switches to an alternative network or profile to restore connectivity within minutes. Backed by a contractual 99.95% uptime SLA, and works alongside Conductor's rules-based failover for layered fleet resilience.
Stop outages
Works with your device
Our IoT SIMs are device agnostic. As long as your device is not set to work with a single carrier, it will work with Hologram.
A global IoT SIM for every use case
SGP.32 Hyper SIMs are now available. The most flexible SIM Hologram has ever made.
Built for commercial, prototyping, and harsh environments that demand a longer lifespan.
An industrial-grade SIM soldered directly to your device for permanent, reliable connectivity.

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 global and able to 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 is SGP.32?
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.
What is Conductor?
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.
What’s the difference between eSIM and eUICC?
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.
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.
Are your IoT SIM cards secure?
Every Hyper SIM includes powerful security features like Private APN, fraud detection, and device locking.
