ooooh, first post through my mifi
It works at last.
Ok, here is how to do it. Buy a mifi - I have this one here although the one I had was supposed to be unlocked, it wasn't for some reason.
I bought a usb dongle when I was in Germany last year so have taken the SIM card from it (which gives me unlimited internet access while I am in Germany). It would not work so I had a quick google and came across this website with unlock codes. It was a bit of a fiddle, till I worked out what I was doing wrong but I got there in the end.
So I spent about ?100 altogether, but both dongle and mifi can be used anytime I am in Germany and the mifi can be used anywhere in Europe, as long as I buy a SIM card. I have one already for France, and for UK.
Then you just top up your SIM card and connect mifi to iPad.
Last time I was in Germany I had a HUGE telephone bill - the data roaming charges are massive in CH, but do check with your internet provider if they offer any savings.
Doing it with the mifi is good for me - as you can connnect up to 5 devices to it so both DH and I can check our mails on our iPhones, and we can use the iPad too.
