When is use my o2 Nokia 6700 as a modem for my lap top when no wi-fi is available I can receive emails fine in Windows Live Mail but I get the error message below when I try and send. Any ideas? I cand send and recieve when I am using wi-fi which suggests the o2 settings are different.
Regards, Gideon.
