CoreESIM leverages established networks in Mexico, providing excellent 4G/LTE coverage in major urban centers like Mexico City, Guadalajara, and Monterrey, as well as prominent tourist regions such as Cancún and Playa del Carmen. While connectivity remains robust in these areas, users may experience reduced speeds or intermittent service in remote mountainous or sparsely populated desert regions. Network performance is optimized for densely populated and high-traffic zones.
