If however you want to spend a lot of time in the UK and visit France for a bit, then perhaps the offer from 3 is a good choice.
After 2017 then maybe all this advice will change. We'll see.
Three is a UK operator which offers low cost roaming in France. We're planning on a few days in the UK and a few days in France and don't need anywhere close to 3gb. Three also offers a 500mb add-on for £5 that can be used in France. For £10 I can get 500mb in the UK (at 1p/mb) and 500mb in France (the add-on). That should be more than enough data and save the effort of shopping in France.
