I am going to spend 4 weeks in France and will need internet access. After lots of research it looks like my best option is to buy a Novatel 3352 Mifi beforehand and then buy a 1-month unlimited data SIM card when I get to Paris.
According to this site: http://prepaidwithdata.wikia.com/wiki/France when I arrive in Paris. It looks like I will need to bring my iPhone so that I can access the #123# menu and order the Internet Max service. Then I assume that I will be able to remove the SIM from my iPhone and insert it in the Novatel 3352.
Has anyone done this or can you suggest an easier way to get one month of internet access via MiFi?
