Tata docomo network connection is very bad in urban areas but it’s also bad in rural areas, if you want to talk anyone you need to go outside of the hous. Data connection of tata docomo are also very bad it’s very slow because the network connection is vsry slow, a one thing of this connection is very good which is the customer service but we need to network connection so in my opinion it’s very bad charges and billing is not bad it is good.
