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.

Frequently Asked Questions for Global Coverage

How does my SIM connect across different networks?

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.

Is permanent roaming access available?

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.

What is the difference between LTE and LTE-M?

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.

Are LTE and 4G the same?

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).

Is Cat-M1 the same as LTE-M?

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

Why are there fewer networks offering NB-IoT?

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 ne
