I'm based in the U.S. and have T-Mobile as my cell service provider. T-Mobile technically provides free data and messaging overseas to all of its U.S. customers, however, when I was in Italy last year, I found service to be spotty at times.
Was wondering if any of you have been able to get decent service in Athens or Nafplio on a T-Mobile account?
I'm specifically curious about whether GPS will work on my phone, as we'll be renting a car and I'm hoping not to need a standalone GPS unit.
Any info/advice appreciated.
