airtel seems to have a messed up backend. so some users get lucky and are not FUPed.
but eventually they find out the lucky ones and fix the system to mess up their connections.
so essentially... this is not a feature. this is a bug.
May be,one more friend is also getting 1mbps constant even after his FUP 10GB,now one question is in my mind,it may be that he keep getting this speed for few months so better he enjoy,or he also think that if its a bug,den may he change his plan from 30gb to 10gb coz fup wont be affacting him,but in case he change plan and they fix issue while plan migration ,that shall be a problem for him!
Do u think so?Changing plan may FIX bug sooner!
