You need the correct APN settings. Have you got them sent to your phone via: http://getsettings.o2.co.uk/ServeSettingsWebApp/
If that doesn't work, you can enter them manually in the phone settings... I don't know where they are on the SGS, but on my phone it's Home -> Menu -> Settings -> Wireless controls -> Mobile networks -> Access Point Names. In there you should find some APNs listed. One of them should have these exact settings:
Access point name: wap.o2.co.uk (contract customers) or payandgo.o2.co.uk (pay-as-you-go customers)
Username: o2wap (contract customers) or payandgo (pay-as-you-go customers)
Password: password
Authentication: Normal
Data bearer: GPRS
Gateway IP (proxy) address: 193.113.200.195
Session mode: Permanent
Port number: 8080 or 9201
URL address: http://mmsc.mms.o2.co.uk:8002
...if not, add one which does.
