Explanation:

With the consideration of TRAI Recommendation on “Ensuring Adequate Numbering Resources for Fixed Line and Mobile Services” Department of Telecommunications has taken the decision of implementing the following:

• All Fixed to Mobile calls will be dialed with prefix ‘0’ from 15th January, 2021.
• There will be no change in dialing plan from fixed to fixed, mobile to fixed and mobile to mobile calls.
• Suitable announcement will be made for the same. This announcement shall be played whenever a subscriber dials a fixed to mobile call without prefixing ‘0’.
• All fixed line subscribers will be provided with ‘0’ dialing facility.
• A total of approximately 2539 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 ofconnections can be added in future which will be beneficial to the mobile customers at large.

Hence both statements are correct.
