I live in Bangalore. Was using Vodafone where network issue was there so I planned to switch to Docomo because of their marketing claim of best network coverage. But the whole claim of network is completely false. This company has the worst & poor network coverage even in the city.
Now, another hell issue is, I would have to wait for 3 months before I switch to any other provider.
Guys, do not go for Tata Docomo. Do not but tata docomo mobile sim or connection.
