How Do M2M SIM Cards Work?
Anyone who has ever owned a mobile phone will have at least a sketchy idea of what a SIM card is. It’s the part that enables devices to communicate. And to save important data. In mobile phones, this means things like contact details, and message contents. Without a SIM card, most phones are little more than pretty shells. And the technology behind the SIM is versatile, allowing it to be used in multiple devices for numerous applications. Hence its widespread adoption throughout the business and industrial ecosystem.
But while standard SIM cards do have their uses in business, the technology has evolved further, leading to the development of M2M SIM. So, what does that mean? And how do M2M SIM work?
M2M SIM Cards – What You Need to Know for Your Business
What are M2M SIM for?
Developed specifically for machine to machine (M2M) communication, M2M SIM facilitate the collection and transfer of data in a wide range of devices and scenarios. Ideal for the age of the Internet of Things (IoT), where smart devices are reducing the need for human intervention across a range of processes and applications, M2M SIM have become integral across sectors.
How does an M2M SIM card work?
The core of the M2M SIM is the same as the traditional SIM. It is basically a form of device or user identification. But the functionality of M2M SIM cards is different. Although voice services are available, most M2M SIM are used for text-based communication. This includes the sending and receiving of vast amounts of data, where required. And they do this through a reduced data rate… Which probably sounds like a negative thing, but in reality, equates to a lower consumption of cellular data and power for each interaction. Making M2M SIM more efficient for data heavy processes.
M2M SIM cards also carry additional functionality. Including card management. So, if your company is using a network of cards, you can distribute the data allowance where it is needed most, avoiding unnecessary cost.
What are the benefits of using M2M SIM cards?
While most machine to machine communication can be conducted via traditional SIM, there are numerous benefits of working with dedicated M2M SIM cards.
Network surfing
A key advantage of M2M SIM is that your devices are rarely left without coverage because they have the ability shift between different cellular networks. And it’s this that makes them so useful within the PHV and taxi sector, as well as transport and logistics. Assets are highly unlikely to drop off the radar because they have infinite roaming potential.
Security
The security of M2M SIM will always depend upon your provider. But the SIMs were designed with security in mind. The right provider will afford a private APN (Access Point Name) accessed through a VPN (Virtual Private Network) for your SIM communication. This guarantees that you always have a secure tunnel for data transfer, preventing unauthorised data access.
Durability
M2M SIM were originally developed for industry, where they could be reliably used in a variety of environments. This meant that they needed to be stronger than the original SIM cards. M2M SIM can withstand extremes of temperature and movement. They can be used indoors or out. And they can be used for long periods without detrimental effect.
Remote accessibility
Wherever in the world the device you are monitoring is based, with M2M SIM you have remote access to its data. You’ll need an app and the IP address entry point, but it puts you in control of all of your assets from any distance. Reducing the need for boots on the ground.
Scalability
M2M SIM were created for scalability. Once you’ve done the groundwork, implementing M2M SIM within your business infrastructure, networks can be added to or changed relatively easily. So, the SIM are there to meet your business needs, as you need them.
M2M SIM are not fundamental to the efficient management of a business or its assets. But they are very beneficial. As seamless communication and data gathering increase in importance and business performance, M2M SIM have the potential to make business smarter. And a whole range of sectors have already discovered the advantages they can bring.
