Re: 3G activation

Navigate to:
Make sure MMS Messaging is enabled (if you wish to use this feature)
Now navigate to:
Settings>General>Network>Mobile/Cellular Data
Make sure Cellular/Mobile Data is enabled. Then input these settings:

Username: giffgaff
Password: password
Visual Voicemail: (giffgaff does not support Visual Voicemail)

APN: Leave Blank
Username: Leave Blank
Password: Leave Blank

Username: giffgaff
Password: password
MMS proxy:
MMS Max Message Size: 2097152
MMS UA Prof URL: Leave Blank
Then you must power off your phone and switch it on again. The Internet and MMS settings are now complete.
N.B. If the Cellular/Mobile Data tab does not appear, see this guide:

If your internet still doesn't work after inputting the settings, use this guide:
If you have problems with certain apps such as YouTube, Whatsapp etc. not working properly, see this guide:

Voicemail is enabled by default. To disable it dial 1626. To re-enable it dial 1616. To ring voicemail, the number is 443 (the original voicemail button won't work).
If you would like an easy access method to your voicemail, follow these steps:
On Safari, go to:
Press cancel on the prompt to call 443 that comes up. Then press the or button at the bottom of the page, and press Add to Home Screen.
Press Done, and you should have an icon to call your voicemail. Alternatively, a good substitute for Visual Voicemail is �HulloMail�. You can download this on the App Store if you wish.

To find out how much credit you have left, dial *100#
To find out how many minutes you have left in your goodybag, dial *100*7#
To find out how many texts you have left in your goodybag (Hokey Cokey users only), dial *100*5#
Your iDevice will say O2-UK as the carrier, because giffgaff uses O2's signal. If you would like to change the text to giffgaff or make the original Voicemail button work on the iPhone, there are long winded ways of doing these things which require jailbreaking. PM me if interested.
Lastly, if you have any questions about using an iPhone on giffgaff (or just about giffgaff in general), don't hesitate to PM me (go here:
Enjoy giffgaff!
