Now I am in Delhi and I have been using Airtel SIM for last 3 years. My connection is prepaid. Its service worst. Calling every time break and I disturbed always in my area.
Internet speed so slow and so buffering in my area. Airtel Bharti is famous in world and many people use Airtel SIM.
Sometimes ago Airtel is amazing but now a days not attract its customers.
Thank You
