Guess its time for Indians to start sharpening their memory coz from Jan 2010 Indian's are going to have 11-digit cellphone numbers. Its official and DoT have also confirmed that all the 10-digit numbers would exhaust by August this year.
Think about it, the different numbers possible in 10digits are 10^10 = 10billion different combinations of cellphone numbers. Which is more than 10times the Indian population(theoretically speaking it means every Indian already has 10different numbers.. lol.. :P) !!! But even that is not enough to cater to the Indian communication needs, thereby needing an extra digit from Jan 2010.
A little bit of mathematics here using simple combinations would tell you that the total number of extra numbers as a result of adding that 1 extra digit is 15937424601 (thats a little over 15billion different new numbers)!!! Phew...
Guess its goina be pretty long before we talk about 12digits...!! :)

thats intresting...but u see all digits start with 9 so there may not be 10 billion digits available...
anyways as u said it might not be too long before we hit 12 digit..either we have to adopt number portability asap or find an alternate mode of identfication instaed of just keep on adding digits
How did you manage to come up with those stats? there are (10^11-1) numbers with 11 digists. From 00000000001 to 99999999999!
