This specific plan is valid only within Uruguay. This is the most important question for travelers. If you are taking the Buquebus / Colonia Express ferry from Buenos Aires (Argentina), your connection will stop in the middle of the river. For this, we highly recommend our Latin America Regional eSIM to stay connected seamlessly in both countries.
