I AM USING VODAFONE FROM LAST 10 YEARS. I had also used all other service provider but Vodafone having great network and service. Vodafone is resolving the issue on the spot or take little bit time to resolve the issue.
I think, no one customer would be suffer from any problem with vodafone. That’s the best part of vodafone.
The other part is cost of service, which is also comparatively higher than other services.
