Yeah, I am a tata docomo user . I am using tata docomo network since 2 years without any little bit of problems . it’s my favourite network because it has a great service in all over india and they are providing a lot of less payable reharges to their users .
they have very cheap recharges of message packs, internet packs and call offer’s .
I think they have to maximise their network signal problems . at some places their network signals are not so good but overall they are providing a best network to their users .
