The Department of Telecommunications (DoT) has asked telecom service providers to start issuing 13-digit digit numbers for SIM based machine-to-machine (M2M) services, which will co-exist with 10-digit numbers. However, the change will not affect mobile phone numbers, which will continue to have 10 digits. 


The DoT had approved the scheme involving M2M services and a letter on it was sent to various departments on February 9, 2018. SIM-based Machine to Machine services are direct communication devices such as point-of-sale machines or even smart devices like latest refrigerators. Contrary to recent confusion, SIM based machine-to-machine have nothing to do with the commonly used SIM cards in mobile phones.

During the meeting, it was decided that 13-digit M2M numbering plan will be implemented from July 1, 2018. From this date onwards, all new M2M mobile connections will be allocated l3-digit numbers only.

The DoT said all service providers must ensure that their network elements including IT and other relevant systems are aligned with 13-digit numbering for M2M SIMs before July 1, 2018. Migration of existing 10-digit M2M numbers to 13 digits will start latest by October 1, 20I8 and shall be completed by December 31, 2018, it said.
