I am assuming u have activated your gprs and downloaded the settings.which operator r u using? Whichever it is ,the default settings u might have downloaded never work on the 7710.if u r on airtel maharashtra, I can give u the settings,but ill have to search. Had written them down. Or u can try calling up the customer care and tell him/her to give u the settings for 7710.mention that specifically. though talking to them may not be a great help.
