Economic times report says that ,night top up is only for speed plus ,economy combo ,executive combo and turbo starter plans ,now these are all hourly based plans ,I would have loved if they had offered anything like this with volume based plans ,that way it would have solved both my downloading and surfing needs .Moreover they have not mentioned speeds for this night top up .I doubt if they wud allow unlimited d/L for paltry Rs 50 ,Or this cud be just a LTd period offer to attract new customers.
