I read on this answer from RedBaron:

Pre-activated SIM cards are not sold in India. This means you have to buy a SIM card and then wait for some time for the number to get activated (this can vary from 2 to 24 hours).

How can I get a SIM card that gets activated within two hours or less in India?

If the location matters, I am located in Hyderabad (Telangana, India), specifically in Banjara Hills (I'm also interested in solutions located at the Hyderabad airport).
