Hyderabad: From 15 January, callers making a call from fixed-line or landline to mobile phones will have to dial numbers with prefix '0', the Union ministry of communication announced on 25 November.
There will be no change in the dialling plan while calling landline to landline, mobile to landline, and mobile to mobile.
The ministry, in a statement, said, "With the consideration of TRAI recommendation on 'Ensuring Adequate Numbering Resources for Fixed Line and Mobile Services', the department of telecommunications has taken the decision."
An announcement shall be played whenever a subscriber dials a fixed to mobile call without prefixing '0'.
The ministry also said that approximately 2,539 million numbering series is expected to be generated from the above. This will free up sufficient numbering resources for future use. "With the freeing up of sufficient numbering resources, more number of connections can be added in future which will be beneficial to the mobile customers at large," said the ministry.
The changes have been done in order to allow minimum inconvenience to subscribers and also free up essential numbering resources.
In May, the Telecom Regulatory Authority of India (TRAI) suggested dialling with prefix '0' for calls made from landline to mobile phones. It clarified that the introduction of the prefix for certain kinds of calls is not the same as increasing the number of digits in the telephone number.
