Worldwide Reach

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).

Streamlined Connectivity

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.

Transparent IoT Pricing

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.

Com4’s eUICC SIM cards enable seamless connectivity across multiple networks with a single SIM. If your device changes location within a country and loses its current network connection, it will automatically connect to the best available network. Similarly, when your device travels to another country, it will connect to the top available network in that region. This functionality is built into our SIM cards. However, selecting the right data plan on the Com4 dashboard is crucial for accessing networks in the required countries. If uncertain, consult our Sales team. You can always adjust your data plan after initial testing.

Yes, our standard data plans include networks that offer permanent roaming access. In regions where permanent roaming is restricted, such as Turkey, our custom plans provide temporary access. This is beneficial for devices that frequently move across countries without staying in one location for over 90 days.

LTE (4G): This is a widely adopted technology that significantly increases data speeds compared to 3G. While not specifically designed for IoT devices, its global availability makes it a popular choice for many IoT applications.

LTE-M (Cat-M1): Designed specifically for IoT devices, LTE-M is a "low-power wide-area" (LPWA) technology. It facilitates the transfer of small data amounts over large distances with minimal power usage. However, LTE-M is less available than LTE because not all operators have implemented it.

Yes, LTE and 4G are often used interchangeably today. LTE, which stands for "Long Term Evolution," was a step towards achieving the fourth-generation network (4G).

Yes, LTE-M and Cat-M1 refer to the same technology.

NB-IoT, designed for IoT applications, stands for "narrow band" and is a type of LPWA technology. It enables efficient data transfer over large areas with low power consumption. However, its adoption by network operators has been limited. Additionally, NB-IoT has connectivity challenges for devices that frequently move and need to reconnect to new towers. In such scenarios, LTE or LTE-M are better options.

Com4 SIM cards can access over 750 networks worldwide, chosen for their permanent roaming access and reliability. When multiple networks are available, the cellular modem and firmware in your device will scan and connect to the network with the strongest signal. Network availability is influenced by factors such as your device’s band compatibility, geographic location, tower traffic, and device firmware settings.

“It’s critical that the IoT connectivity just works. With Com4, it does – and that’s why we chose them.”

"Com4 enables a reliable and efficient connection at all our customers’ stations. It is of the utmost importance for us to have a supplier who can guarantee that our communication works smoothly and reliably in all nine countries where we operate."
