Hay guys how are you all I am back with tata docomo service I am using this signal from last 9 months I am facing lot of problem in this while travelling from one place to another in our country I got a signal problem in this network at some of the places in our country there is no signal please do not buy this sim if you are travellers because it connectivity is not good or its net speed is very slow it is very expensive network as compare to the other networks
