US IPhone 5S in France
I have an Iphone 5S that I plan on taking to France. Last time I did that with a 5C I was told to buy a nano SIM card which I did (at an Orange store) but I could never get away from the Orange carrier requests. Does that mean the card was locked? How can I get a card that is not tied to any carrier? What should I ask when I buy my nano sim at a kiosk or store? Thank You very much.
