Generally the cheapest way is to buy a pay-as-you-go SIM in your year abroad country/ies and keep your UK phone so that you can use all the apps etc when you have wifi.
We hope that helps!

If you've already got a phone, get it unlocked before you leave and you can get a SIM card in your host country. Alternatively, 3 have abolished their roaming charges in both Italy and Switzerland so when I was in Italy I just got a rolling contract with them for about £7 a month and put the sim in my unlocked phone. You can use your phone just as you would at home, and you still get all the texts/data/calls. I thought this was a bit easier than getting an Italian PAYG one because you have to go into a shop to reload them every few weeks.
