Excellent, inexpensive connection. Easy to sign up and connect. It didn't work in Monaco, but that's manageable. It worked great in Austria, Hungary, Italy, and France.

I used it in the Netherlands, Belgium, and Switzerland. It worked perfectly and smoothly without any problems! The large data capacity was great; I could use Google Maps and other apps without worrying about data limits. Thank you!
