Our carrier-agnostic IoT SIMs grant access to multiple networks no matter where you deploy. Expanding into new countries? You won't need to negotiate or integrate with new providers. With Multi-IMSI technology, our SIMs can store various subscriber identities and switch profiles as necessary. Additionally, eUICCs enable you to remotely provision SIMs with new profiles Over-the-Air (OTA).
Com4's carrier-agnostic IoT SIM cards empower your devices to link up with over 750 cellular networks across 190 countries. Whether you're after 2G, 3G, 4G, LTE-M, NB-IoT, or 5G connectivity, rest assured, we have you covered.
At Com4, we prioritize flexibility. There are no minimum contract durations, and you can freely upgrade, downgrade, or pause subscriptions at your convenience. Our transparent pricing model ensures that you only pay for active SIMs. Choose between a pay-as-you-go approach or our data-pooling option to avoid unexpected costs, ensuring that you only pay for the data your devices actually use.

An IoT SIM card is a specialized SIM card designed for use in Internet of Things (IoT) devices. Unlike traditional SIM cards, which are primarily used for voice calls and text messaging, IoT SIM cards are optimized for data transmission and machine-to-machine (M2M) communication. They typically have larger memory capacities and are more durable to withstand harsh environments.
An IoT SIM card contains a microchip that stores unique information about the device, such as its identity and credentials. This information allows the device to connect to a cellular network and transmit data. IoT SIM cards can be activated and managed remotely, making them ideal for large-scale deployments.
IoT SIM cards come in a variety of form factors, including:
No, not all IoT SIM cards are tied to a single carrier network. Some IoT SIM cards are global and can connect to the best available networks in any region. This is particularly useful for devices that need to operate in multiple countries or regions.
eUICC stands for embedded universal integrated circuit card. It is a technology that allows a SIM card to support multiple subscriber profiles over its lifetime. This means that an eUICC SIM card can switch between different cellular carriers without requiring physical replacement.
An eSIM is the physical hardware that supports eUICC. It is a type of SIM card that is embedded directly onto the device's circuit board. eSIMs are typically smaller and more durable than traditional SIM cards, making them well-suited for IoT applications.
