Hi, I would like to know if its possible to get a BSNL 3G sim from U.P & use it in Delhi with a datacard for 3G Internet ? i.e I hope there are no data roaming charges when it uses MTNL's 3G network in Delhi? From what i can understand from the BSNL site; this doesnt seem to be possible. Just like the voice roaming charges, there will be Data roaming charges. Bharat Sanchar Nigam Ltd :S:S But some seller of UMG1831 in delhi has told me otherwise.. Any answers, anyone?
