Here's the Solution to this Question

To increase numbering resources, so as to cater to the rising demand for telephone numbers:

The first way is to move on to 11-digit numbering scheme for mobile and continuing with 10-digit numbering for fixed line services and shifting data only mobile numbers (like dongle connections) from 10 digits to 13 digit numbering. This can produce 1010 x 3 which is 3 times more than the current number system.

The second way is to use number series start from 3, 5 and 6, etc. The current provision of 10-digit mobile numbers starting with 9, 8 and 7 have a total capacity to grant 2.1 billion connections. By using this system we can produce 6 x 910 which is also 3 times more than the current number system.

India has reviewed its numbering plan twice earlier – 1993 and in 2003.

The new numbering plan in 2003 created space for 750 million telephone connections – 450 million cellular mobile and 300 million basic phones, factoring in a 50% tele-density by the year 2030.
