I have a spare Airtel sim card which I had brought from Haryana and used there. I am now back at home in Roorkee and have no use for the sim card but would like to keep it active so that when I next visit Haryana I would be able to use it again.
How do I keep my Airtel sim active without having to use it on a regular basis and spending money on it?
