I will be in Austria May 27-June 10 and I have added the International service from AT&T. I asked AT&T if, when in Austria, I should dial from my iPhone as if I were in Austria or in the US; they told me to dial as if in Austria. In the "Dialing" section of the new edition of RS's "Vienna, Salzburg, and the Tyrol", however, the instructions are to use the International rules for dialing within Austria with my US number. I am confused. What should I do? The concierge has given me this number: +43 664 5119910
When I arrive in Salzburg, what should I dial?
Thanks
