Bangladesh eSIM Guide 2026
Bangladesh has better urban connectivity than most visitors expect. Grameenphone and Robi both provide solid 4G in Dhaka and the main cities. Cox's Bazar's tourist strip is well covered. The Sundarbans, the world's largest mangrove forest, is offline beyond the forest edge. Biometric SIM registration is mandatory for all operators, making the eSIM arrival advantage more valuable here than in most countries.
Grameenphone covers over 75% of rural Bangladesh at 4G and is the network partner behind most Bangladesh travel eSIMs. For any route beyond Dhaka, Grameenphone is the correct default.
Bangladesh in one screen
Grameenphone (GP) is Bangladesh's largest operator by subscribers and the recommended network for travel eSIMs. GP covers approximately 75% of rural areas at 4G and maintains the best connectivity along the main tourist routes from Dhaka to Cox's Bazar and Khulna. Robi is faster in urban centres. Banglalink is the third significant operator. For travel eSIMs, Grameenphone is the standard network partner.
All Bangladesh SIM cards require biometric registration with a National ID or passport. Airport registration takes 20 to 40 minutes plus queue time. A travel eSIM bypasses this entirely and provides immediate connectivity for CNG auto-rickshaw booking apps and Dhaka navigation.

Bangladesh eSIM FAQ
Do I need biometric registration for a Bangladesh SIM?
Yes, all Bangladesh SIM cards require biometric registration with a passport for foreign nationals. The process takes 20 to 40 minutes at an authorised outlet plus queue time. A travel eSIM bypasses this entirely and provides connectivity from landing.
Is there signal in the Sundarbans?
At the entry points of Mongla and Khulna, yes, with Grameenphone 2G to 3G. Inside the Sundarbans mangrove forest, no signal on any operator. Download offline maps and save boat tour operator WhatsApp contacts before departing Khulna.
Which network is best for Bangladesh travel?
Grameenphone for any itinerary beyond Dhaka. GP covers 75% of rural Bangladesh at 4G and maintains the best connectivity along the Cox's Bazar and Khulna routes. Robi is faster in Dhaka's commercial areas.
How much data for a ten-day Bangladesh circuit?
5 GB comfortably covers ten days including Dhaka, Cox's Bazar, and Chittagong. The Sundarbans days consume almost no data. Dhaka's navigation complexity drives the highest daily consumption.
