We use the internet for so many of our daily activities that staying connected wherever you go now seems more like a necessity than a luxury.
When traveling abroad, however, there is usually the question of how to do that without running into high roaming charges (or even whether your mobile device will be able to connect to a global network at all!). If you know you will need to make phone calls, it may be worth it to look into getting a French SIM card, but if what you'll need is primarily a way to get online, some french companies have come up with a simple, affordable solution.
Travel Wifi and My Webspot rent mobile hotspots (also called mifi). It is a small device that fits in your pocket, and allows you to stay connected for your stay in France without paying the huge data roaming costs, at any moment (hotel, street...).
My Webspot is also available through partnerships with tourism professionals such as Hotels, Tour Operators, Travel Agencies, so that you can book your hotspots in a rapid process (less than 3 minutes) to order, retrieve and use the hotspot.
