By looking at the plans offered and provided by the MTS operators I was very impressed with them and thought of giving a try with the data card so I bought a prepaid data card from MTS, for the first few months it really worked fine with me but after a few months or so it started to give problems as the dongle was not getting connected and I tried contacting the customer support as well but did not get any proper solution from them any time, speed is pathetic not at all a reliable dongle or a network.
