Vodaphone is good brand name in the telecom industry but they are not doing justice to there brand name. I am using vadaphone 4g sim in my redmi note 4. In the name 4G they are cheating customers.The internet speed of 4g network is very slow. The network signal are also not good some times their is lot of disturbance in the voice call. I call customer service many times but they did not give any resonse to me. I am very disappointed by the behaviour of customer service.
