I using airtel since 4 years ago. I fully not satisfied with airtel but I just like airtel. my parents and family member also using it. My moble is suitable for dual sim card so. I using airtel for just incoming call and sim to using for other work like outgoing, Internet etc.
I not using airtel for out going because it is very costly.In my area not range for 3g so I dont use it for Internet.I like it network range, because it range arrrive all over india.it is costumer service also good.
