First of all, it is not worth having tata docomo connection, because a loads of network issues and definately billing issues even after paying the bills on time connection is disconnected, it is been 15 days since complaint is lodged through customer care(talking to them was another issue they dont know what is customer service) issue hasnt been resolved. Walked to the outlet asking for status, no response received.
In one sentence, Docomo is a pain, never ever go for it. If you have their connection already then I dont have to explain it;)
Crazy Docomo. It should be renamed as hocomo. huhuhu
