It looks like a modernize for the improved in implementation of BSNL broadband plan alteration these days. Earlier BSNL used to linger for start of every month for implementing the broadband plan modify but now they do it within a few days. I tried to change my plan on 24-1-2011 and my new plan was activated right after 4 days that too was having one national holiday in between. In fact it looks like to have altered even in advance but because of some misunderstanding the incorrect user id was conveyed. So the real transform happened right on 2nd working day.
