Since their introduction in 1991, SIM cards have evolved to bring connectivity from simple mobile phones to the Internet of Things (IoT) devices. According to Ericsson, by 2024, 4.1 billion connected IoT devices will have cellular connections. Machine to Machine (M2M) communication is key in the emerging Industrial Internet of Things (IIoT). From automotive telematics and fleet management to personal care services, M2M SIM cards can now power a variety of different usages.
IoT devices can serve critical usages, such as monitoring elderly people and alert relatives in case of urgency. Those devices need to have access to network connectivity at all time and recover rapidly in case of disruptions. That is why manufacturers are now deploying multi-network IoT SIM cards to automate processes, enhance performance and maximize uptime in remote locations. Indeed, companies are looking for connectivity solutions that are easy to deploy, to manage, and to use and most importantly guaranty a strong and stable connection at all times.
Standards, a Vital Enabler for M2M SIM Cards
While 3GPP standards like GSM, GPRS, SMS, 3G, 4G (and soon 5G) which are now part of our daily lives, allow us to establish a wireless and universal connectivity to the Internet, the LightweightM2M (LwM2M) a messaging protocol for client-server M2M interactions created by the Open Mobile Alliance SpecWorks (OMA SpecWorks) is used for remote management of devices in the IoT. The combination of LwM2M over 3GPP standards offers a complete, interoperable and secure solution for operating and maintaining remotely IoT device fleets.
Matooma one of our partners understood very quickly the benefits of including remote diagnostics and device management features into their IoT offering.
Julien Muller, Matooma CTO believes that “standardization responds to a market need. When you plan to deploy hundreds of thousands of connected objects all over the place, you need to make sure you will be able to manage and update them remotely because maintenance can be costly. With the adoption of remote diagnostic and (re)-configuration features leveraging on open standards, we offer a sustainable solution for our customer to diagnose issues, fix misconfigurations and maintain their devices over-the-air. This avoids sending someone to perform the necessary changes on site, and cuts significant maintenance costs operating device fleets.”
Device Management a New Feature for SIM Cards
Imagine that you monitor elderly people at home and discover a defect that requires you to change a configuration in the way the tracking device accesses the network. You just can’t go to each people’s house and change the desired setting on-site. Having a remote diagnostic and re-configuration system that works over-the-air and is able to operate even when the data plan is broken is a critical consideration when launching such devices and related critical services. You need to think about how corresponding devices will be managed and updated through their lifetime.
“Device management is key to the success of any future IoT projects,” says Hatem Oueslati, CEO and co-founder of IoTerop “because once you have deployed your connected devices in the field, you need to make sure to keep them insight! Remember there will be bugs to fix, configurations to change, software to update, devices to recover and repair…”
Beyond connectivity, industrials need a solution that will provide all services needed for managing device fleets seamlessly, changing networking configurations over any network operators (GPRS, 3G, 4G, LTE-M, NB-IoT), updating their firmware over-the-air and securing deployments with encryption and authentication. In this perspective, IoTerop, which could be referred to as the TeamViewer of the IoT, is working on an end-to-end solution offering remote diagnostics and device management functionalities able to operate seamlessly over a multi-connectivity and multi-operator context.
