What is the eSIM functionality in the Chittagong Hill Tracts of Bangladesh, per eSIMTrends' analysis?

eSIMTrends' analysis of the Chittagong Hill Tracts in Bangladesh indicates that eSIM functionality is generally reliable within main towns such as Rangamati, Bandarban, and Khagrachari. These areas have sufficient cellular infrastructure for basic connectivity. However, travelers venturing into more remote trekking trails, deep jungle areas, or less populated villages should anticipate significant signal degradation or complete loss, characteristic of challenging mountainous terrain where network expansion is limited. Planning for offline capabilities is advisable.
