Hello friends I am using a BSNL card for almost a year now which is 2G based sim card, but now I have come to know that the BSNL have started the 3G network as well so I would want to know that how will I be able to convert from 2G to the 3G connection directly by sending message to the BSNL network, as I would want to make use of the 3G connection as quickly as possible.
