CoreESIM provides strong 4G/LTE coverage in key urban and regional centers across Peru. Users can expect robust signal in major cities like Cusco, Arequipa, and Lima. Connectivity is also reliable in the port city of Puno, situated on Lake Titicaca. In the Amazon region, specifically Iquitos, CoreESIM maintains good 4G signal within the city limits and along major river routes, though signal strength may diminish in deeper, more remote jungle areas due to infrastructure limitations.
