If I talk about this tata docomo I also have this sim before 2 years I do not like this signal due to if I go to hill station then firstly, I have lots of problems like signals so what can I do. Then I purchase vodaphone it is much better than other and after 2 kr 3 years this company is closed due to some problems so I think if the person buy some things so it will be better to proper check signals and data pack if I talk about data pack it is more expensive like 3 gb for 28 days so, I think it is not good company and much expensive as well as singnal ptoblems are also not good
