Machine to machine communication may seem futuristic but it has already come to reality. Machine-to-Machine or popularly known as M2M communication can open up to enormous opportunities, as rollout turns out to be more far-fetched over different parts. M2M can bring significant and remarkable social and financial advantages to buyers, organizations, residents, and governments. M2M is the reason for mechanized data exchange amongst machines and a monitoring place for different industry verticals like Smart City, Smart Grid, Smart Water, Smart Transportation, and Smart Health and so on.

What is M2M Sim?
M2M simply stands for Machine to machine communication. Through this, machines connect with other and communicate and collaborate among themselves by sending and receiving data over the internet through sensors. M2M sim enables all the connected devices to communicate among each other.

Despite the fact that M2M alludes to non-human; specialized, gadgets still ought to have an exchangeable convention which is utilized for receiving and sending information. The network is accomplished by either embedding or installing a Machine-to- Machine SIM in the gadget that is later designed for the home server where all the necessary information is gathered and can be segregated for organization's useful purposes or further research.

Types of M2M Sims:

M2M SIMs can be divided in three parts:

 Classic SIMs
 Industrial SIMs
 Automotive SIMs

Classic SIMs can be seen at wireless marketplaces and are advertised for PDAs, cell phones, and other handheld gadgets, different from M2M SIMs. Despite the fact that a Classic SIM works in a M2M or IoT gadget, they are intended for typical working conditions. SIMs composed particularly for M2M utilize cases incorporate Industrial M2M SIMs and Automotive M2M SIMs.
M2M SIMs have diverse characteristics for an assortment of the industry cases. M2M SIMs can have a more prominent storage limit and a higher number of read-write cycles, which means it has a more drawn out lifetime than a Classic SIM. With information maintenance of up to 17 years, M2M SIMs
outlast Classic SIMs. Furthermore, M2M SIMs are created with materials that empower them to work in crude natural conditions, for example, deserts or ice climate.

Automotive SIMS also SIMs are created by keeping the harsh conditions in mind to continue functioning even in high temperature and vibrations. Not just for car vehicles, these SIMs can be utilized for remote sensors and different gadgets that need to keep going long in rough situations.

Benefits of M2M SIMs:
There are multiple benefits that can be availed through m2M SIMs such as:

 The best and foremost part is the flexibility which gives the freedom to choose among the mobile operators according to the need and suitability even after the deployment of the SIMs.

 The connectivity I reliable as it is specifically made for IoT devices.

 The pricings are competitive and mobile service providers compete with each other to get the major chunk of the business so they compete quite heavily on the price front which benefits the end customer.

 Through the connected management platform, the connectivity and monitoring can be done all the time and in case of any anomaly, it can be noticed within few minutes.

 Instant scalability is possible where SIMs can be availed on demand and coverage change can be accomplished without any hassles.

 The bright future of IoT depicts the importance and market potential of M2M SIMs which is growing at an exponential speed year after year and is projected to grow up to staggering 1.3 billion connections through m2M across the world by 2025 which is certainly a sign of bolstering demand from 205 million connections in the year 2014.

 Governments are also encouraging the m2M SIMs for futuristic development and research purpose. New policies are being enacted to accommodate M2M SIMs as the mainstream technology within short span of time. For instance, Government of India has already acknowledged and accepted the future potential of m2M SIMs and have mentioned it in the National Telecom Policy 2012. As IoT is the future, M2M SIMs are backbone of it. There is no doubt o\about the future market potential of this and it is likely to grow even more in the near future when IoT will be inevitable.
