A lot of confusion surrounds the MMS set up of the Acorn trail cameras and although I don't profess to be an expert myself, I've done some research to try and identify why so many people seem to be encountering problems.
Post Update 12.12.2012 : Practical set up instructions for proven SMTP service which works with all Acorn Wireless Trail Cameras.
A common theme seems to be an inability to get the camera to send to an email address.
Below I've shown all the connection settings for using the various Vodafone services as an example. To send an email from the trail camera make sure you are using the correct APN (Access Point Name) and also using an SMTP (Simple Mail Transfer Protocol) which allows authentication.
You may be having other problems and as soon as I can I will try and unravel some of the mysteries. My immediate problem is that I don't have reliable network access at my location and don't use these services; but I will very soon be making tests in a good signal area to try and clarify these issues.
In the meantime I hope that the information below is at least helpful.
