Today is a driving day, with some stops along the way. We are leaving Austria temporarily, returning in May. We do not plan to have internet access in Hungary unless we can find free WiFi at our campground (doubtful, but you never know). We decided it wasn't worth the bother and expense to buy a SIM card for such a short visit (4 days). The good news is, our campground in Poland advertises free Wifi. So, in spite of our saying that we would have internet access 24/7, it depends on which country we're in! We will buy a SIM card for Germany and Switzerland; reusing the SIM card we have in Austria. We are hopeful that we will be able to use our little "mobile partner" in the UK and the Republic of Ireland.
