I am using Vodafone for last 1 month and the experience with Vodafone is worst. Firstly they took 4 days to activate my number.
The network coverage of Vodafone is very poor in my area. Sometimes there is only one signal is my mobile.
Vodafone is very costly then other operators. The call rate is very high. I used there 2g internet for one week. Internet speed is good but only in day time but at night speed became horrible.
There is no 3g signal in my home. Call quality is also not good. Sometimes call gets disconnect automatically. Previously I was using airtel. I can definitely say that airtel is very good in terms of coverage and quality. Airtel is also costly but their service is good. I am going back to airtel. Dont go for Vodafone.
