I have recenty joined GiffGaff and so far the service has been excellent.
So I came to giffgaff with a new unlocked Samsung galaxy s3 and quickly found that the internet and mms service would not work,I tried sending the SETTINGS sms to 2020 but this didnt work, so using the giffgaff community I was able to find the information i needed to set up the phone, so I thought I would give the information back to anyone with the s3 looking for help.
Right this is what I did :-
Open Settings then click MORE SETTINGS
Then click MOBILE NETWORKS
Next click ACCESS POINT NAMES
From here press you menu key which is the touch button to the left of the home button
Next select + NEW APN from here enter this information

MMS port - 8080

APN type - default,supl,mms

After this press you menu button again and select save.
This will take you back to the select APN screen, from here select your newly created giffgaff APN by clicking the small circle next to the giffgaff APN this will make the circle go green
next press your back button and ensure you USE PACKET DATA box is ticked (this option may or may not be there, if it is tick the box, if not don't worry about it, newer versions of android have removed this option)
Then go back to the main settings page and Set Wi-Fi to OFF Return to home screen. Reboot your phone (turn off and on again).
Your internet and mms service should be up and running
Once you have verified your mobile internet is working you can turn your wifi back on
Please note that in order to send mms messages you will need airtime credit as mms messages are not included in your goodybags
