[Lamby]

I want a new device and will pay off the rest of contract however it's not giving me the option to get extra data as my old contract only gives me 10g , how do I get my new phone and more data thanks

You should be able to upgrade the data package here:

Make sure the "keep my number option" is selected to that it is applied to your current sim. If you don't see this option then call Sky on the 150 number and ask them to help you to do this.
