Do you have an ISP at home?
I traveled for years. My ISP had dialup numbers in other cities. Before I left I would search the ISP's list for local numbers in the cities where I was going. At the hotel, change the DUN phone number and put a 9, (comma) in front of the number. Nine to access an outside line and , to add a two second delay.
All major ISPs have numbers in other cities.
