eSIM for Bangladesh — Instant 4G/5G Data Plans

Bangladesh's mobile network is one of the most active in South Asia, served by five main operators: Grameenphone, Robi, Banglalink, Teletalk, and Airtel Bangladesh. 4G LTE coverage is available across Dhaka, Chittagong, Sylhet, Khulna, and most major cities and district towns. Rural areas, the Sundarbans mangrove delta, coastal islands, and remote northern and eastern regions may have more limited 4G with some areas on 3G. Bangladesh has a dense population and active network investment, making urban and semi-urban connectivity generally reliable. MobiSIM connects through supported local networks to deliver strong data performance across Bangladesh's main cities and travel corridors.

Install your MobiSIM eSIM before landing at Hazrat Shahjalal International Airport in Dhaka so you are connected from arrival. Download offline maps for Dhaka, Cox's Bazar, and Sylhet before departing, as traffic and navigation in Dhaka especially benefits from real-time map access. Keep your home SIM active for calls while MobiSIM provides your data connection. Cox's Bazar has one of the world's longest natural beaches and generally has reliable 4G connectivity in the main tourist area. If you are visiting the Sundarbans or remote river delta areas, download offline maps and essential documents before departing Khulna or Mongla, as connectivity in those areas can be very limited.
