No, your CheapESIM plan for Uruguay is specifically designed for use only within Uruguay to provide the most cost-effective data. This is a crucial detail for travelers planning to cross the Rio de la Plata. If you are taking the Buquebus or Colonia Express ferry from Buenos Aires (Argentina), your connection will stop once you are outside Uruguayan waters. For trips involving both Uruguay and Argentina, CheapESIM offers regional South America eSIMs or separate country-specific plans, ensuring continuous and affordable connectivity without incurring unexpected roaming fees.
