As my personal experience Vodafone mobile operator is one of the worst and cheater mobile network. From my home I could not get single mobile connection. Every time I need to talk to someone on mobile I couldn’t talk from my home.
For that I need to go out of my home to get connection so that I can talk. Every time I call to Vodafone customers care for this problem they tell they will solve the problem. But still the connection is like that only not working properly.
