well i know nothing about the requirements for data in india with reliance.so my help will be very limited.try to search for a custom rom for reliance.or maybe the no proxy solution will work with them ?? i really dont know. do they have an andriod plan? if so try the no proxy.it is posted here. if they do and you cant find it i will give you a link. good luck.
or if you cant you might be left with only using the wi-fi.
