AsiaDhakaBangladesh eSIM and Travel Guide: Stay Connected from Dhaka to the Sundarbans
Bangladesh has four active carriers with 4G reaching most of the country and 5G launching commercially from September 2025. Grameenphone leads on rural coverage, reaching into the Sundarbans fringes and the Chittagong Hill Tracts where others drop out. A Roamix Bangladesh eSIM connects you the moment you land at Hazrat Shahjalal International, skipping the 30-minute airport SIM queue. Budget 5 to 8 GB for a two-week trip and always cache offline maps before entering the Sundarbans or the remote hill tracts.
Key Takeaways
- Grameenphone has the widest 4G coverage including remote rural and hill tracts areas where Robi and Banglalink are patchy.
- Robi and Grameenphone both launched commercial 5G in September 2025 in major divisional cities.
- A Roamix eSIM activates on arrival at DAC and saves you the lengthy airport SIM card registration queue.
- Cash in BDT is essential for most of Bangladesh outside Dhaka hotels, as card acceptance is limited.
- Cache offline maps for the Sundarbans, the Hill Tracts and Cox's Bazar beach road before leaving Dhaka.

Most travellers
Instant activation on a local network, skips the lengthy airport SIM registration process and avoids roaming bills.
Local physical SIM
Extended stays needing a local Bangladeshi number
Requires passport, photo and a 15 to 45 minute registration process at the airport or a city store.
Pocket wifi
Groups sharing one connection
Another device to charge, and signal still drops in the same areas where any cellular signal fails.
Carrier roaming
Very short Dhaka business trips
Most European and US carrier roaming rates in Bangladesh are high compared to local plan costs.
For most visitors to Bangladesh, a Roamix eSIM is the most convenient option, saving the airport SIM queue and providing reliable Grameenphone and Robi coverage from Dhaka to the coast.

Get your Bangladesh eSIMMobile Networks in Bangladesh
Bangladesh has four operators: Grameenphone (the largest), Robi Axiata, Banglalink and state-owned Teletalk. All four have 4G LTE, and Grameenphone and Robi launched commercial 5G in September 2025 across divisional cities. A Roamix Bangladesh eSIM connects you to the strongest local network at DAC, bypassing the lengthy airport SIM registration process.
Largest operator with the widest 4G reach across Bangladesh including rural areas, the Chittagong Hill Tracts and the Sundarbans fringes. Best choice for travel beyond divisional cities.
Second-largest operator with strong urban and semi-urban 4G quality. Competitive data pricing and 5G in divisional cities from September 2025.
Strong third-place operator popular for aggressive pricing and youth-focused data plans. Good 4G in major cities, less consistent in remote areas.
Typical Speeds
Dhaka 4G delivers 20 to 60 Mbps. Divisional cities average 10 to 30 Mbps on LTE. Remote areas may see 5 to 15 Mbps.
5G Status
5G commercially live in Dhaka, Chittagong, Sylhet and other divisional cities via Grameenphone and Robi from September 2025.
For Dhaka and coastal travel, Robi and Banglalink offer excellent value. For the Chittagong Hill Tracts, Sylhet tea estates and any rural travel, Grameenphone has the only reliable 4G reach beyond the main roads.
Bangladesh has excellent coverage in Dhaka and divisional cities, but the deep Sundarbans mangrove forest, remote Chittagong Hill Tracts villages and the offshore islands of the Bay of Bengal can have no signal. Download offline maps before any rural excursion.
Bangladesh uses standard LTE bands. Most unlocked phones from iPhone XS onward and recent Android models work on the 4G network.
Data Usage Guide
Data needs in Bangladesh are moderate in Dhaka but increase significantly when travelling to remote regions where offline preparation is critical for navigation.
Download offline map packages for the Sundarbans approach from Khulna, the Chittagong Hill Tracts roads and the Cox's Bazar beach road before leaving Dhaka.

How locals communicate
Bangladeshis primarily use Facebook Messenger and WhatsApp for messaging. SMS remains widely used. Facebook is enormously popular and often used for business communication.
Keep your home SIM active for SMS two-factor authentication while using the Roamix line for data.
Airports in Bangladesh
Hazrat Shahjalal International Airport
Dhaka
Free wifi in the terminal, but quality is variable. Use your Roamix eSIM for reliable data from the moment you land.
Activate your Roamix eSIM before landing to skip the 30-minute airport SIM queue. Use data to book your Dhaka hotel transfer, navigate traffic on the Dhaka Airport Road and contact your accommodation.
Shah Amanat International Airport
Chittagong
Basic terminal wifi. Grameenphone 4G is reliable throughout the arrivals area.
Chittagong is the gateway to Cox's Bazar and the Chittagong Hill Tracts. Use Roamix data to arrange your onward road or bus transport before leaving the terminal.
Osmani International Airport
Sylhet
Limited terminal wifi. Grameenphone covers the airport and surrounding Sylhet city well.
Sylhet is the gateway to Srimangal tea gardens and the Ratargul Swamp Forest. Use Roamix data to arrange a local guide and download offline maps of the tea estate roads before heading out.
Cox's Bazar Airport
Cox's Bazar
Small terminal with limited wifi. Good Grameenphone and Robi 4G in the arrivals area.
Land connected to book your beach hotel transfer, check surf conditions on Inani Beach and download the offline map of the 120 km beach road before your driver arrives.

Get your Bangladesh eSIMMoney & Payments in Bangladesh
The Bangladeshi Taka (BDT) is the only accepted currency. Cards are accepted at Dhaka's larger hotels and restaurants, but cash is needed for almost everything outside the capital.
Cash vs Card
Withdraw BDT at the airport ATM before leaving Dhaka. Card acceptance is rare in Cox's Bazar, Sylhet and anywhere regional. Taxis, rickshaws, markets and guesthouses all require cash.
ATMs
ATMs are available at DAC and throughout Dhaka. In regional towns, Dutch-Bangla Bank and BRAC Bank ATMs are most reliable. Carry enough for your whole regional trip as rural ATMs are sparse.
Payment Apps
bKash is Bangladesh's dominant mobile money platform, widely used for payments at local shops but requiring a local number to operate.
Daily Budget
Budget travellers spend around 800 to 1500 BDT a day for guesthouses and local food. Mid-range Dhaka hotel and restaurant trips run 3000 to 6000 BDT per day.
Data cost: Carrier roaming in Bangladesh is expensive. A Roamix plan covers the same trip for far less.
Getting Around Bangladesh
Bangladesh combines cycle rickshaws in Old Dhaka, CNGs (auto-rickshaws) across cities, intercity buses and domestic flights to reach remote regions. Data is essential for navigation in chaotic Dhaka traffic.
Rickshaws and CNGs
Cycle rickshaws are the main way to navigate Old Dhaka's narrow lanes. CNG auto-rickshaws are used citywide. Use Roamix data to agree prices with drivers using a map and avoid getting lost in Dhaka's complex road system.
Rideshare
Pathao and Uber operate in Dhaka. Both require a data connection to book. Pathao also connects motorcycle taxis which are the fastest way through Dhaka traffic.
Intercity buses
Long-haul air-conditioned buses run between Dhaka, Chittagong, Sylhet and Cox's Bazar. Use Roamix data to book seats on operators like Hanif or Green Line and track your departure from the busy Dhaka bus terminals.
Domestic flights
US-Bangla Airlines, Biman and Novoair connect Dhaka to Chittagong, Sylhet and Cox's Bazar in under an hour. Use your eSIM to check in and manage bookings.
Regions & Travel
Bangladesh offers remarkable density of culture, history and nature in a compact country. The ancient Mosque City of Bagerhat, the world's largest mangrove forest at the Sundarbans and the 120 km Cox's Bazar beach are all accessible, but reliable data for navigation and booking is essential. A Roamix eSIM keeps you connected from Dhaka to the coast.
Best time to visit: November to February for dry, cool weather ideal for the Sundarbans and hill tracts. October and March are shoulders with good conditions. April to September is monsoon season, with heaviest rain June to August.

Language
Bengali is the national language and spoken everywhere. English is understood in Dhaka's hotels, upscale restaurants and by educated residents. Outside Dhaka, English is limited and a translation app is very useful.
Tipping
Tipping is not strongly expected but appreciated. Around 10 percent in Dhaka restaurants is a kind gesture. Guides and boat operators on Sundarbans tours appreciate a tip for good service.
Food & Dining

Frequently Asked Questions
Bangladesh eSIM, connectivity, and travel
What is the best eSIM for Bangladesh?
Roamix is a top choice for Bangladesh because it connects to local networks like Grameenphone and Robi, which together cover the major cities and rural areas. Activating before you fly means you skip the lengthy airport SIM registration queue at DAC.
Do I need a SIM card for Bangladesh?
You do not need a physical SIM. A Roamix Bangladesh eSIM gives you local 4G data on arrival without the passport photo and registration process required for a local SIM card.
Which network is best in Bangladesh?
