Hello friends, with my experience Tata Docomo is a bad network in India when you I went to Ajmer there is no network and customer care is not responsible for network before 4G I use this sim very slow Internet with work on 2G network not faster than other networks
I call to Customer is not co-operating on network problems of users
I search for new offers on Tata Docomo but price is high for 2G data and talktime recharges have some best offers but data is very slow for users after using other
That’s why I recommend you to buy sim of responsible customer care and which network in India full network anywhere and faster Internet with better experience
