Machine to Machine communication is another milestone in the world of smart homes and cars. It basically revolves around SIM card based communication via the machine to the customer/distributor regarding information like consumption levels, stock running out, GPS location, etc. It is basically used by Smart Cars, CCTVs, vending machines, etc.
The telecom department, after understanding the importance of M2M communication, has informed all the operators about a 13 digit number scheme that will be given to these machines for exchange of information. The plan will be implemented from 1st of July, 2018. However, it will not impact any users as they will still be using the 10 digit mobile number scheme. The 13 digit scheme is strictly for machine to machine communication.
