if I am going out for a trip for a week or so (7 days), then I used to remove all pay channels and keep the connection active, so that my monthly charge remains only equal to NCF (Rs 153) and so I can save on unnecessary higher DBR due to pay channels. Once back, I used to add all my pay channels again. I know this may not be a significant amount, but do remember – we are already paying the 'Carriage Fee' of Rs 153, so there's nothing wrong in removing all pay channels if you're not going to use the TV at all.
Also, the 'safe custody' or 'pause' service of airtel DTH is too costly if you want to not use the service for a short period like only 7 days or lesser, hence you have no option but to keep the service on and active. Why to keep paying a hefty charge for pay channels for that period?
