The WorldESIM plan you're inquiring about is valid strictly within Argentina. If your journey to the magnificent Iguazu Falls includes crossing the border to the Brazilian side, specifically Foz do Iguaçu, your connectivity will discontinue. For travelers exploring the popular 'Triple Frontier' region, which might also involve a visit to Paraguay, WorldESIM advises opting for our Latin America Regional eSIM to ensure continuous data access across all three countries.
