Tata dicomo is the rubbish mobile operator in punjab users. Because its bill rates and internet rates are too high but internet speed is very slow even 3g so. I give u. An advice dont use tata docomo .and one more thing that it gives no information about anything like no. Internet, minutes etc this ckmpany is fake. So dont use this mobile operator it poors all persons bcz of its high charges even call charges so. Dont use tata docomo.
