This specific SouthESIM plan is designed to work exclusively within Mexico. While Mexico shares a border with Belize, these are two distinct countries with different mobile networks. If your travels take you across the border into Belize, your current Mexico eSIM will likely lose its connection. For seamless connectivity in multiple countries, consider one of our multi-country bundles, which are perfect for travelers exploring more than one destination in Latin America!
