First up, buy your micro sim from EE's eBay store, it's currently 99p. It comes pre-loaded with £4 credit plus a £1 text and talk pack, which can then be used to make purchases through Google Play by enabling the "mobile billing" option in your payment options. This is accessed via the PlayStore menu and through your account settings.
Having an EE Sim also has a couple of other juicy perks including 2 for 1 cinema tickets and PizzaExpress every Wednesday, plus commuters and travellers in London can connect to WiFi whilst on the Underground.
