For your device to work on giffgaff,then it needs to be unlocked or locked onto the o2 network.There are a number of ways that this can be achieved .
1) Contact your current service provider and they can unlock it for a small fee.
2) You can take your device to any phone shop or market and also have it unlocked on o2,again for a small fee.
3) There is an unlocking service for most devices and there are also many websites than can unlock your device for free.

I tried to find an unlock service for the 4030x but failed.
I paid an ebay service but they returned my money say they couldn't do it.
In the end I rang T-Mobile and paid £20.49, they said it would take 10 days.
After 10 days they sent me an SMS saying it would be 10 days (20 days)
I rang them and complained, but it still took nearly 20 days.
They sent me an unlock code which worked perfectly.
I then inserted my GiffGaff SIM and all was OK.
No more rip off PAYGO data charges.
