I used Tata Docomo many years but for a year this operator is very poor service. Tata docomo prepaid talk time recharge policy is similar to other operators and internet plans is better like rs. 249 - 2.5GB 2G with 56 days, rs. 95 - 750MB 2G with 21 days and many other plans but internet was too slow and websites page opened very late and the internet pack provided me lot of troubles. Tata docomo prepaid special tariff plans are awesome like rs.14 local & STD mobiles call 20p/min & 30p/min but there is lot of problem like network problem many hours in 24 hours network gone and customer care service is very headachy for customer. So, I request to other customer that do not buy this sim and do not connect tata docomo operator.
