Once again BSNL has revised the Data plans and now the 2G data plans are missing i.e they have only 3G data plans which is applicable for all 2G and 3G subscribers and there is no capping in speed in 3G bandwidth. This is good for 3G subscribers but seems not to be good for 2G subcribers who use internet in 2G mobile handsets or in some areas bsnl has no 3G network there this plans is so much costly. BSNL has also introduced new 3G/2G data plans for daily, weekly or monthly basis but these plans are too costly.
"In short you can say you have to pay same price whether you are using 2G or 3G data plans." They say this uniform 2G/3G data plans. These plans are working from 15 Aug 2013. You can see all the data and other plans on the bsnl official website http://bsnl.co.in under Mobile section.
