When we landed in Zurich the first thing I did was seek out the SALT store in the airport. SALT, formerly ORANGE, is a telecommunications provider in Switzerland. I purchased a prepay data card which they installed in my Smartphone so that I could have GPS navigation and web surfing throughout Switzerland.
We next rented a car and found that our timing was unfortunate in that it was rush hour in Zurich which meant the autobahn was at a standstill.
