I live in Dhanbad ( Jharkhand) and I am using Tata Docomo form 4 year its internet is very very bad it does not have 3G in Dhanbad ( Jharkhand) I dont know why but it doesnt have its 2G internet does not give the speed of 30 kbps also its very very slow.
I have to wait for the page to open sometimes it take 1 min also. There is not much responce through the customer care so please dont buy it to use internet because of its low speed.
