In the home area. both Vi and Airtel are good. In foreign, they both usually tie up with same career. But sometimes Airtel has problem connecting. idk why. Vi is good, but they have 1 very sh!tty practice. If my bill is not paid within the due date. They will disconnect the connection. Immediately. I am stuck in a foreign land with no cell service. No way to receive the OTP and do the payment even to resume service. But idk if Airtel does that or not. That's prepaid at the moment.
