tritesh 1 Report post Posted December 5, 2011 from since morning i am not able to connect to dial up connection using bluetooth modem. Whenever i tried to connect it shows 720 error . I have already tried the solution given at microsoft's kb article at number 810979; but it did not work for me. Is there any way other than to format my system to resolve this problem. I have already tested my mobile on other system it works fine and establish connection. Share this post Link to post Share on other sites
