sorry, I'm not that of a social media user so I came here to ask for help from indians.
my cousin will fly to Chennai in a few days and I want to know about the isp, sims, packages with suitable deals and stuff.
he will have a sim from the provider "Airtel" which will work in India without any issues but I don't know if that Sim can signed up for any credit or data packages in there.
so does anyone have any idea about this stuff? does he need to purchase a new SIM from there? what are the good deals and packages for it? or can he just rely on roaming?
highly appreciate everyone who can help me up with this. thanks
