We have recently been contacted by a Virgin Mobile Broadband user who has advised us that they do not provide an SMTP server for use by their customers for sending emails. This user has fixed their problem by switching to using SMTP2GO as their SMTP server while connected to the internet through their Virgin Mobile Broadband2Go service.
As SMTP2GO is a worldwide SMTP service, it works from any location in the world where coverage is available. Setup is once-off, generally takes less than 2 minutes, and involves changing your SMTP server, and changing your SMTP port setting to 2525.
More information can be found at the SMTP2GO homepage.
