Prepaid SIM for data in France
I have been searching for this but I found so many different answers and some of them are pretty old so I don't know what to do.
I will be in France for about 4 days and would like to get a prepaid SIM card to use it to access the internet through my phone. Since I would be using it mostly for e-mail and Google Maps and Google Navigation I suppose some 100 Mb would be enough.
Are there any first-hand recommendations for carriers that can provide a prepaid SIM card with a data plan or at least a good price per Mb without one?
