My friend activated and sent me the same so I am not sure how, but when I read Tre's UK site, they said it works in 18 countries. Just that you have to roam on their partner network (manually search & set).
Otherwise you can get local sims - not at all complicated to buy or use. In Paris, Lycamobile is cheap & has good network (leaders Orange & SFR have expensive plans). Lyca sim costs €10 which has €5 credit. If you refill another €5 (making it total €10 balance, you can activate 1 GB data pack for one month).
