I have been using tata docomo sim from 4 yrs now sometimes it cannot catch the netwotk in many areas and many times the call drops sometime it doesn’t catch the network in my home also the call rates is very high compared to the other mobile operaters the customer support is also very bad customer care no.
Is not toll free also the 2g and 3g internet speed is very low the sometimes 3g runs like the 2 gb if they will not solve the problem of network and their customer support I have to switch to different operater. I will not recommended this to anyone bacause of the network and internet problems the two main things.
