For a while, I've been toying with getting an iPad for use when I'm out and about instead of my MacBook Air. I regularly travel to France, and I'm wondering how I would use my iPad there without paying huge data roaming charges to my home operator. With the Air, I simply purchased a French 3G dongle and SIM without a contract, and buy internet access as and when I need it. French mobile operators charge for PAYG 3G in a completely different way to their UK counterparts: instead of buying an allowance of a certain number of MB that you can use over 24 hours or 30 days, you buy a certain amount of time online that you can use over 15 days. How on earth would this work with an iPad, which has push email and on which you are in effect permanently connected instead of manually dialling up? And which of the French networks allow the purchase of a microsim without contract, for which data can subsequently be bought? Any French nationals or regular business visitors to the country able to help with this?
