CoreESIM delivers excellent 4G/LTE coverage in major Bangladeshi cities such as Dhaka and Chittagong, and extends reliably to popular tourist destinations like Srimangal (tea gardens). However, in extremely remote or ecologically protected areas, such as parts of the Sundarbans mangrove forest or very isolated villages, network availability may be limited or non-existent. Users should anticipate reduced signal strength in these peripheral zones, consistent with typical rural telecom infrastructure.
