Cheap calling rate, fast internet and reliable network is need of every person today.Nine months back Tata Docomo was seen to be one of the most promising mobile network operator after launching its 3G services and attractive offers but as the time has passed the Tata Docomo has changed a lot problem of network was since I bought but it got intensive in last few months.I have 3 Sim of docomo but none of them I use now as there is no network near my home and work area.
I strongly recommend to avoid buying Tata Docomo until the situation change.
