please help! i was on the phone with straight talk's customer service service for almost an hour and a half and just went in circles! the default 'tracfone multimedia' access point settings on the tracfone branded straight talk nokia e71 do not work. error message 'unable to send message' sms worked out of the box, managed to get the internet working with a new custom access point, but haven't figured out the correct settings for mms.
Perhaps try Googling for "Straight-Talk-SIM-in-an-Unlocked" and go to post #23 there for details of Tracfone APN
