Tata docomo is fastest growing mobile operator all over the country. Its customer is about every corner of india. But this company unable to provide its mobile network of network tower to them. I also belongs from a village when ever I go to my house there is no network of tata docomo company which makes sometimes more irritating and a feeling generates for break my sim. Sometimes network is catched if vodaphone. In this situation you can talk but not use internet. Bwcause the vodaphone networks makes your phone iin roaming and no data pack will be used. The internet charge is directly deducted from your main account.
Overall tata docomo is good in its tarrif is quite cheap and best for normal person. Full talktime is available at low cost. But the only thing which is poor is its network. The data pack of this mobile operator is very cheap is you compare with other mobile operator.
