My trip is equally divided between Germany, Bavaria, France, Alsac, Colmar and Switzerland, Scuol.
I have in the past bought SIM cards for each country for data and phone.
I arrive and depart in Munich.
A Europe based phone is good.
Data is for maps, search.... maybe 2 gig in 3 weeks.
Any guidance would be welcome, especially if I can do it in Munich and not get SIM in each country.
If I need to do this, please help me with recommendations for providers.
thank you for your help
