Hello
Tata Docoma is the worst company I have ever seen. The company was nice in the initial years but after few time the service and signal gradually descreased.The network is worst. The internet spped is less than 2G and I think that the best way to resolve the problem is to shut the company or port your number to some other company.The customer service is worst and need many upgradations and requires more investment . The bill charges are high as regarding to the services and network. So guys please donot use this network
