Traveling to UK and Paris: best nano sim?

[wayland1985]

Ill be headed overseas next week, for Paris and the U.K. I just purchased a new 6sPlus with the apple upgrade program, so I'm assuming it's unlocked.

I wasn't sure if there was a prepaid nano-sim I could purchase for each country? If so, which network is best?

If possible, I'd love a UK based sim that will work in Paris... As my French is non-existent, so buying one in Paris might be an issue.

What about a Three prepaid sim card ? They have different plans going from about £10 to £20.49 and they have the feel at home that enables you to use your sim card in some countries including France as in the UK. So that means using your plan and not being charged for roaming.

I don't think you will find a similar prepaid deal in France anyway
