I am sharing my views tatadocomo.I use tatadocomo past 5 years but tatadocomo networks quality is good in city but tatadocomo networks not available rural areas.
Tatadocomo networks only available city .but out off city networks quality very poor. Tatadocomo call rate is cheapest price other telecom and tatadocomo 3G networks not available my areas.only 2g networks available.tatadocomo 2g data pack is cheapest price.
I advise to tatadocomo that their networks improve in rules areas. Customers service is very good.
