Telecom operators in their meetings with TRAI have said that they have to deactivate SIMs to efficiently manage number series (mobile phone numbers) allocated to them by the Department of Telecom.
TRAI said it has found that telecom operators do not follow common criteria to disconnect inactive SIMs but added that “to manage their numbering resources better, the service providers have proposed to follow a procedure for deactivating mobile connections which are not used for a long time.”
In July 2011, DoT started allocating number series to telecom operators on the basis of active users on their network.
