Landline users must add "0" to call any mobile from January 1
TRAI has decided in May 2020, to guarantee adequate numbering resources for fixed-line and mobile services.
The decision has been made to ensure adequate numbering resources for landline and mobile services. TRAI, Telecoms regulator had recommended the move in May 2020.
A DoT's November 20 circular said that all the landline subscribers should be provided with '0' dialling facility and STD dialling facility. All telecom service operators have given time until January 1 to implement the directive.
DoT said that appropriate announcements could be placed on landline switches to inform landline subscribers of the requirement to dial the prefix "0" for all landline-to-mobile calls. This ad must be played every time a subscriber dials a call from a landline to mobile without prefixing the number with "0".
However, the regulator had said that the introduction of dialling a prefix for a particular type of call does not amount to increasing the number of digits in the phone number.
