If you need to stay connected, you need your own WiFi hotspot
Get 4G/3G internet in France with a mobile WiFi hotspot, so you are connected not just in your rental or hotel, but wherever you are.
As you may know, the cost of 'data roaming' in a foreign country makes it impossible to use your phone or other device for internet use unless you happen to own AT&T. But this WiFi hotspot device costs from 6 euros per day with unlimited data use.
The device is a small wireless modem, smaller than a cellphone, that gives you fast and secure 4G connection (or 3G if 4G coverage is not available where you are).
It requires no set-up, you just turn it on and then you can connect up to 10 devices to it wirelessly.
You order it ahead of your trip and it is delivered to a hotel, rental, or any address of your choosing in France, so it is waiting for you when you arrive. You can also pick up in person from Travel WiFi's Paris office, and get a cup of coffee and some trip advice while you're there. At the end of your stay you just pop it in a pre-paid envelope and mail it back to them.
