Tata Docomo is my favourite because from last four years I am using it.
At starting its call rate is very chep like 1p/1s for local and STD also.
at that time I am using net also which is 50 Rs. for 1 GB.
Now a days the call rate and net rate both arise in all mobile operator. In Docomo it change but than other todays docomo rate is only 1.2 p/1s that is also cheap then airtel or idea which is nearer to 1 Rs. for 1 minute. one more thing from last month I got offer of Rs.199 which include talktime of Rs. 199+ 1 GB 3G internet. It’s awesome. I am using it. For call rate there is plan of Rs. 97 for 250 Local+250 T2T minutes free for 28 days.
Note:- This all review based on my city Bhavnagar
Thank you.
