For the last couple of years we have used a 3 data sim in a mifi in France with no problems. A bit slow but ok. So we changed our phones to 3 so that we could use them in France this year along with another data sim in the mifi. I don't know wether iPads use more data than iPhones but with little usage the 12gig in the mifi is used up after 6 weeks. With the phones, which we use most of the time, we have 4gig as part of our package and only use about 2gig a month. Phones not connected to mifi. Also I have never seen 4g while we have been in France, only 3G, and the internet speed is so slow, much slower than last year. 3G is ok in uk for utube videos or even watching tv! Certainly can't do any of that here in France. I can't remember seeing anything in t&c that says Internet connection will be much slower when used abroad. Where am I going wrong? Or is it all a big con? Thinking of buying a French data sim for the mifi.
