DoT released instructions on May 16, 2018 in relation to SIM cards used for Machine-to-Machine ('M2M') communication services[1] ('M2M SIMs'), along with related Know Your Customer instructions for issuing M2M SIMs to entities providing M2M communication services under the bulk category and instructions for Embedded-SIMs.The entity providing M2M services may require SIMs from a telecom licensee authorized by the DoT for the purpose of providing connectivity for M2M services. The instructions from the DoT clarify that the ownership of all such M2M SIMs must be with the entity providing the M2M services. Further, in case of a sale or transfer of devices having M2M SIMs, the entity providing M2M services will be responsible for (i) intimating the telecom licensee(s) from which the M2M SIMs are obtained of the details of persons to whom such devices are transferred; and (ii) fulfilling the subscriber verification norms. The telecom licensees are also required to regularly update these details in their database.[1] Machine to Machine (M2M) Communication Services means services offered through a connected network of objects/devices with identifiers in which Machine to Machine (M2M) communication is possible with predefined back end platform(s) either directly or through some gateway. ‘M2M Communication’ refers to a communication between two or more entities (object/devices/things) based on existing and evolving communication technologies that do not necessarily need any direct human intervention.
