A SouthESIM plan for Argentina is designed to work exclusively within Argentina's borders. So, if you're visiting the incredible Iguazu Falls and decide to cross over to the Brazilian side (known as Foz do Iguaçu), your connection will pause. For travelers exploring this vibrant 'Triple Frontier' region, which might also include a quick hop to Paraguay, we suggest our comprehensive Latin America Regional eSIM. It's perfect for keeping you connected across multiple countries without a hitch!
