Yes, IoT cards can support switching between networks of different operators. This feature allows for greater flexibility and coverage, especially in scenarios where a device might move between different geographical areas with varying network coverage.
For example, consider a logistics company that uses IoT devices to track its fleet across the country. As these vehicles travel from one region to another, they might move out of the coverage area of one mobile operator and into another's. With an IoT card that supports network switching, the devices can automatically connect to the strongest or most appropriate network available, ensuring continuous communication and tracking.
In terms of cloud services, Tencent Cloud offers IoT solutions that can work in conjunction with such IoT cards to provide seamless connectivity and management. Their IoT platform allows for the integration of various devices and services, enabling efficient data collection, processing, and analysis, regardless of the network operator.
