I just want to know the minimum 3g internet speed of vodafone according to trai guidelines. My number is [protected].
After 750 mb my data speed throttle upto 64 kbps even in 3g network. So where are you maintaining the guidelines of trai.Please explain me through email only. Otherwise i will have to lodge complain to trai and in rti. Speed is decreased upto 64 kbps on 3g network. I think, it is unfair. While i am getting 3g network, then why aren't you maintaing the minimum speed of 3g?Explain it only trough e-mail not by calling to me.As i want written explanation of it.
