I have a Three 321 sim in my unlocked phone and put £10 on it maybe 6 months or even a year ago and it still works but maybe make a phone call and or check your balance every 3 months to keep the sim registered

I've got a Virgin sim as a backup. I didn't use it for over a year and it still worked when I tried it. They also have a "big data" deal where you get 1GB data when you top up £10. You can use the £10 credit as well.
