SIM cards that are traditionally used in IoT devices are usually designated to a single network provider, meaning that the device has only one option for connectivity. However, adopting a multi-SIM approach can provide more than one connectivity option for each device.
This approach can be achieved by installing multiple SIM cards in a single device, or by using a multi-network SIM card that can hold multiple profiles. This approach can significantly enhance the likelihood of maintaining constant connectivity. These options also allow IoT devices to switch to better quality networks or switch between different regional or in-country operators while on-the-move.
