Tata Docomo network is good but for call charge not for internet because not high speed internet and customer service also bad I made few calls to customer care. I always get a robotic answer that you compliant will get resolved in 48 to 72 hours. But I never happens. Even I got the sms that complaint resolved Second trick is you will never get any answer in email. The customer care department always call you.why is it so, sometime I have net problem like I tried to connect internet but I can’t, so sometime tata docomo is good and sometime is not good
