I have buy two sim of Tata Docomo. But I am not happy buy the sim. Tata Docomo provide a bad network for him. Its data packeges rates very high. Tata Docomo is big brand. His network is not working. My village no range for Tata Docomo. His network service is very poor. Tata Docomo internet speed very slow. Their Custmer care service is poor.
