The easy but not so cheap way to get internet access on your PC is via the Tether app.

The harder but free way is shown here.

You will need the T-Mobile, APN settings (if you are on T-mobile), namely:

APN – general.t-mobile.co.uk
Username – (leave blank)
Password – (leave blank)

See here for other UK network settings.

Once that is working, you need to setup internet sharing on your laptop, to give yourself a local WiFi.

Windows/PC – how to.

Mac/OSX – how to.

After that you should have access to the internet via WiFi from your laptop.

Hope that helps…
