Indian telecom subscribers will have to prefix 0 as they call from a landline to any mobile number starting January 1, 2021.
The decision will ensure adequate numbering resources for fixed line and mobile services. Telecom regulator TRAI had recommended the move in May this year.
A DoT’s November 20 circular said that all the fixed line subscribers should be provided with 0 dialing facility, STD dialing facility.
All telecom service operators have been allowed time till January 1 to implement the directive.
DoT said that suitable announcements may be fed in the fixed line switches to inform fixed line users about the requirement of dialing the prefix 0 for all fixed to mobile calls. This announcement should be played whenever a subscriber dials a fixed to mobile call without prefixing 0.
