Delete the giffgaff APN settings, restart the phone, put them back and restart the phone again. See if that solves it.

Can you recheck your internet settings? My mobile data is working on an iPhone 4s. Did you recently upgrade your iOS?

[ Network Issues & More ]

'Quick Options to try'

1, See if theres any problems in your area

giffgaff operates as a mobile virtual network operator using the O2/Telefonica network

2, Turn On Airplane Mode (if you have this option) And then turn Off after about 20 sec

[ Alternatively ]
Take the battery out for 30 sec and then place it back in and power up (not for Iphone users Etc)

3, Try :

4, Or hand clean the sim very carefully

[ Well worth a try if its a data / internet issue ]

[ Internet Settings Problems ]

Try deleting any old or even giffgaff wap/mms settings if you have them already, Delete (data) / (wap) (internet) settings then power off your phone then back on again and retry the settings and see if that works

[ Quick Internet Settings & More if you get stuck at all ]

Check O2 status, the local mast maybe not working to well. Also I find just restarting phone can fix

Re: mobile data not working!!!!

These are the iPhone data settings (you may have to redo them if your phone has been updated recently or they have become corrupted):

Settings>General>Network>Cellular Data Network
Username - giffgaff
Password - password

MMS settings:
Username: giffgaff
Password: password
MMS Proxy:
MMS Max Message Size: 2097152

Next you should go to Settings>Messages
and check that "MMS Messaging is turned ON
Then Switch your iPhone OFF and then back on.
