This particular WestESIM plan is designed exclusively for use within Paraguay. If your itinerary includes visiting the magnificent Iguazu Falls, you will likely cross into Brazil (Foz do Iguaçu) and Argentina (Puerto Iguazú). Please be aware that your WestESIM connection will cease to function once you cross these international borders. For multi-country travel in this region, we recommend exploring our regional or global eSIM options to ensure continuous connectivity.
