Vodafone is really an amazing network.It’s call quality, it’s internet speed everything is amazing compared to other operators.I was using a Vodafone SIM from last 5 years& recently ported my Tata DoCoMo number in it, Yes I do agree that it is a bit expensive compared to other’s but to remember that Quality do come when you are ready to spent a fortune on it.It’s catchphrase that Wherever you go, our network follows is up to the mark.I have used all Sim & have never found a satisfaction like Vodafone anywhere. .If you want quality then surely go for it
