DataESIM offers cellular coverage within the primary towns and more populated areas of the Chittagong Hill Tracts, such as Rangamati, Bandarban, and Khagrachari. Users can expect reasonable signal strength for essential communications and data access in these centers. However, due to the remote, rugged, and densely forested nature of the surrounding hilly terrain, signal availability will predictably diminish or cease entirely on trekking trails and in deep wilderness areas. It is advisable to prepare for intermittent or absent connectivity in these regions.
