I have used bsnl network since I had bought my first cell phone. each and every one in my family uses bsnl network.
I live in deep rural areas of Maharashtra still I get good network coverage from bsnl. For a middle class teacher the call rates are very low.
The minute packs provide good talk time so I can talk to my children a much as I could. bsnl internet is rather slow in my city but the rates are very low so its OK . I do not think me and my family are ever going to change our cellular network.
