I am using Vodafone postpaid since 3-4 months. At the beginning it used to be good. Internet speed call quality was good at the beginning.
As the time passed, now I am facing problems in calling Internet and connectivity issues. While call network suddenly goes. Same thing happens while Internet surfing many times I have sticked in the payment page. Sometimes network automatically goes and I have to search networks manually which is frustrating. I will be changing it within a week.
