You may be familiar with SIM (subscriber identity module) cards found in cell phones, but did you know SIM cards are also used to serve a range of applications other than mobile phone usage and tracking? The purpose of SIM cards is to access wireless networks and transmit data, which makes them a cornerstone in the development of Internet of Things technology. Due to the elaborate and industrious nature of IoT, the applications an IoT SIM card must endure are much more rigorous and taxing than the abuse an average cell phone takes, presenting new challenges for the card itself.
IoT SIMs and Durability
An average cell phone won’t have to weather the extreme temperatures and conditions as the machinery used in IoT technology. Since IoT technology can be used to track information for machines across a broad range of industries, IoT SIM cards need to be able to withstand both the freezing temperatures of the Arctic and smoldering conditions of a steel mill.
IoT SIM cards must also be able to survive tough conditions in constant movement because, oftentimes, the devices being tracked are doing very hard, very intense work. Industrial strength SIM cards are corrosion resistant so changes in weather or moisture will not ruin the card. These SIMs will continue operation through extreme vibrations and temperatures ranging from -40 degrees to 105 degrees Celsius.
IoT SIMs and Longevity
Along with being incredibly durable, SIM cards used in industrial IoT applications must also last longer than SIM cards used in cell phones. The average lifespan of a cell phone ranges from two to three years, and its SIM card is designed with this in mind. Cellular SIM card technology is constantly changing to take advantage of technological advancements, innovation, and the high turnover rates of consumer electronics.
Unlike their consumer cousins, IoT SIM cards used in industrial devices are often situated in hard-to-access areas, making them physically and monetarily impractical to replace, even as new developments in industrial technology are made. Practically, IoT SIM cards used in these machines need to be able to last up to 10 years, and not just as a piece of hardware. The cards themselves hold data, and there is a point at which that data may be lost. SIM cards used for industrial IoT applications are designed with high quality materials to prevent this from happening.
IoT SIMs and Communication
Most cellular networks are confined to a specific area or country, and the SIM cards provided for them only have access to certain transmission frequencies. While this is suitable for most consumer applications such as price checking items at the mall or texting your friends to see if they want to grab lunch, companies looking to take advantage of the information provided by IoT platforms may have offices and equipment all over the world, requiring their SIM cards to remain in a constant state of roaming. Cards used for these applications need to be able to transmit data over different networks to ensure a continuous connection; a silent SIM card is a useless SIM card.
