Industry 4.0 (fourth industrial revolution) is driving the convergence of physical and digital systems, revolutionising the manufacturing and industrial sectors. At the heart of this transformation is the Internet of Things (IoT), which connects countless devices, sensors, and machines to gather and exchange data.
A key enabler of IoT connectivity are IoT Data SIMs, which are specialised SIM cards designed for the unique requirements of IoT devices. In this article, we explore the crucial role played by IoT Data SIMs in Industry 4.0 and how they are transforming various industries.
M2M SIM cards, also called Universal Integrated Circuit Cards or UICC, store the credentials and security keys that uniquely identify a cellular subscription. The SIM uses a so-called IMSI number, or International Mobile Subscriber Identity, which is unique for every connected device on or off the network, anywhere in the world.
An IoT/M2M SIM card is a variation of the traditional SIM card used in smartphones, with additional features designed for IoT devices. SIM cards designed for the Industrial Internet of Things include greater durability, security, and flexibility. Machine to Machine SIM cards work by establishing a connection to your host network and transferring data between your device and the rest of your IoT platform.
A significant proportion of IoT devices are remote or mobile and require roaming across multiple networks. However, the way in which your SIM card connects to networks outside of your primary network can vary. Unlike SIM cards for consumers, IoT SIM cards offer the option of either steered or non-steered multi-network roaming to align with your requirements.
Steered IoT SIM cards prioritise the network of your chosen provider, even if there are stronger networks available. They remain connected to your preferred mobile network operator until they are completely out of range, which may result in IoT devices losing connectivity or operating with a very weak signal if no alternative network is selected as a fallback.
On the other hand, non-steered IoT SIM cards do not give preference to specific networks and instead connect to the strongest available network, even if it is not the original provider's network. This can be achieved through agreements between operators that allow non-steered SIM cards to use the strongest available signal. Non-steered connections are particularly crucial for many IoT devices, such as medical or tracking devices, where uninterrupted connectivity is essential.
IoT connected devices are generally any piece of hardware that is connected to the Internet and sends data on either itself or the environment the device is in. IIoT devices are used in a variety of industries, such as Utilities and Energy, Healthcare, Retail, Manufacturing, Transportation & Logistics, Agriculture/Smart Farming, or Automotive.
