If I recharge/activate the prepaid 999 plan (60 GB for 120 days validity without daily FUP) once but then exhaust the 60 GB data part well before 120 days, then can I again recharge 999 plan to be able to use 60 GB again, or do I have to wait til 120 days gets over and in the mean time only be able to recharge with the booster/topups?
