Tata docomo is a third class network provider. No network to anywhere. Cheap recharge of internet. But network not in mobile. I was used tata docomo for using internet, but I was so frustrated about that network. I was port network in idea and now I m happy about this network.
And I never take again tata docomo sim card. And I also give suggestion all of u, check the network on home or office before purchase tata docomo.
