All of my numbers are more than 15 years old...My main AirTel number being almost 20 years old...I can't discontinue these numbers now as they are being used in various places...Like AirTel in all the banks, Vodafone number is with my customers, BSNL number (which I ported from AirTel because of the cheap recharge amounts) is with my relatives etc...I know maybe it doesn't make sense to you but since I am using these numbers from more than a dozen years, I can't close any of them...
My main number is AirTel & it's also linked with all my banks, sites etc & I need to do a little bit calling also sometimes to banks, various customer care departments etc so 23 plan is not for me as it doesn't provide any talktime...I am not sure if Vodafone's 24 plan is still there or not...I need to check that...I can use the 24 plan on Vodafone if it still exists as I use Vodafone for incoming only...
