What is an IoT SIM card and How is it Used in IoT Devices?
The Internet of Things, or IoT, is the definition used to describe the physical ‘things’ (objects) that have the ability to process, sensors or other technologies that can connect and exchange data with other ‘things’. M2M refers to point to point or machine to machine connectivity whereas IoT is the internet extending into machines.
These ‘things’ connect and exchange data over the internet and other communications networks (3G, 4G, 5G etc).
Traditionally a SIM card runs on one mobile network (a consumer SIM) however, for IoT / M2M there are multiple choices including multi-network roaming SIMs available. Where a Smartphone connects to one network, an IoT SIM card will connect to multiple networks to ensure connectivity is maintained at all times.
If you are looking to control, measure or monitor an asset, you’ll use an IoT device (‘thing’) that needs guaranteed connectivity through 3G and 4G SIMs with managed data. Whatever you’re looking for Focus Group can supply you with the right SIM card for the right deployment.
