Actually I want to change my Voice Plan under BSNL as,
Old Plan : VALUE ALL CUL
To
New Plan : LL-SULABH 99 CTD (as advised by friend
@whitestar_999 )
But Friend
@whitestar_999 , what
@sling-shot commented is true.
It's a bit intimidating at first. After logging in successfully in CC portal of BSNL,we won't find anywhere or any link for modification of Plans.
It is only when you click onto the ACCOUNT NUMBER of your BSNL landline number, you are opened to a page that consists of all types of modifications,subscription fee modifications,etc,.etc........
I successfully am going on through the modification links,for change of my plan,but at the last page there was a pretty delay and ultimately showing a Gateway error on to that page,rendering un-modification of the plan.
Simply put,there are procedures online for modification but we are unable to do that.
