iPhone settings for Giffgaff

It’s easy to use your iPhone on Giffgaff. First you must ensure that your iPhone is either unlocked or on O2. Next, simply go to the Home Screen then tap Settings > General > Network > Cellular Data Network and input the following settings:

Cellular Data:
Username: giffgaff
Password: password

Username: giffgaff
Password: password
MMS Proxy:
MMS Max Message Size: 307200
MMS UA Prof URL: [Blank]


Voicemail is automatically enabled but you can turn it off by dialling 1626 and turn it on by dialling 1616. The voicemail button won’t work but if you go here you can add a new voicemail icon to your home screen. Or you can always access voicemail by dialling 443.


Turn your phone off and on again and your iPhone will now be fully set-up with Giffgaff! Visual Voicemail won’t work but there are free alternatives and calls, SMS and MMS messages, mobile data and Facetime all work correctly.

    Hi, I just got an iphone 6 (bought outright) and order a nano sim from giffgaff. I’m a current giffgaff customer and have transfered the sim from my old iphone 4 to the nano and that went smoothly. The problem i’m having is that i have no internet (3g)or send or receive phone calls. My phone shows that I have full bars and the 3g icon appears, but i can’t send or received calls or use the 3g for internet what so ever. Under my Celluar Data, my APN shows up but there is no MMS option what so ever which i beleive is the problem. I have downloaded the giffgaff profile, but is says in red that it is ‘Not Signed’ next to Signed by. What should i do? I’m at a lost as to what i should do. Should i order a new sim? Many thanks in advance.
