I was searching for a solution, on net.... I came across a blog, where some people were discussing simillar issues, and they confirmed that they were sharing the accounts. swapping was possible. but they all were from banglore, may be there bsnl uses different manner too setup dataone. Also, they said that it is possible for 250 startup plan as most of them were on this plan and were sharing couple of 500 plans & 900UL plans. - May be they were bluffing.... I cant seem to use my friend's account 🙁 ............ or then may be just 900UL accounts are restricted.. so many questions... and no solutions.,....-pranKster.
