A major roadblock to implementing full mobile number portability (MNP) across the country has been removed. Several telecom operators have begun simplifying the process of dialling STD mobile numbers in the country. Until now, calling mobile numbers registered and situated outside one’s home network would require adding ‘0’ or ‘+91’ as a prefix. That is not true any longer.
Customers of most telecom operators can now call any mobile number in the country without adding any prefix. We tested this with various numbers on Airtel, Vodafone and MTNL’s networks and can confirm that the prefix is no longer necessary.
