Dear Sir,

I intend to bring to your notice that I have got nokia N73... I hv got a sms from 5919823 that if I want to retrieve the mms, I should go to the site http://125.21.241.88/mms and login with my no. as username and password as sent... but at the site the username n password is not accepted... Kindly let me know what is the problem and how can I get the mms...
