Tata Docomo mobile operator is not an best choice for comnucation. Because it has an high rate plans. And tata docomo is not have an speed you need. It also fails in coverage area. But the costmor service is cool one. If you buy a tata docomo sim then you will think that you got an bad choice. The call rate is normal till the six months of the oprator you select. After that you will charge more than the other oprator. You can also chose an caller tobe for your personal number. I does not perfer this mobile oprator.
