I am a user of vodafone sim and I really dont like its network condition because there is so many network issue at most of the place where I go. Its customer care service is not so good like I have called so many times on its customer care service to tell about the problem of network issue, everytime they tells me we are providing you one more tower service in your area because this is so many peoples problem of your area and wait for a month we will definitely help you.
I did this call at last year and today also my network condition is same to same and when I again called on customer care they again tells me the same thing
