Best eSIM for Bangladesh 2026: 12 Providers Compared

Bangladesh is so densely populated that 4G from Grameenphone, Robi and Banglalink reaches most places a visitor goes; the Sundarbans, the river chars and the Chittagong Hill Tracts are the main gaps. Bangladesh is dense, green and river-woven, from the buzz of Dhaka to the world's longest beach at Cox's Bazar, the tea hills of Sylhet and the Sundarbans mangroves. Staying connected in a country that runs heavily on mobile is essential, and an eSIM is the cleanest way to do it, avoiding the local SIM registration visitors face. Install before you fly, land at Dhaka, and your phone connects when it finds a local network.

Grameenphone, Robi or Banglalink: what nPerf measured in 2026

Four operators share Bangladesh: Grameenphone, Robi Airtel, Banglalink and the state-owned TeleTalk. In the nPerf 2026 mobile barometer for Bangladesh, based on tests run between July 2025 and June 2026, Grameenphone ranks first overall with 59,562 nPoints. Robi Airtel posts the fastest download speed at 30.41 Mbps, just ahead of Grameenphone's 29.37 Mbps, while Banglalink records the lowest latency at 33.9 ms. TeleTalk trails on every indicator.

For a visitor, the gap between the top three matters less than where you go. Grameenphone's footprint is the one locals trust outside the big cities, which is why it tends to be the default on travel eSIMs. Which network a Simsima plan uses is listed in its details, so check it there before you buy.

Buying a tourist SIM at Hazrat Shahjalal Airport

Bangladesh created a dedicated tourist SIM in 2023. Under the BTRC guidelines reported by The Financial Express, a visitor can register up to two SIMs per passport, valid for 7, 15 or 30 days, and each one is checked on the government's Central Biometric Verification Monitoring Platform. That means a fingerprint scan, your passport and your visa at an operator counter, typically in the arrivals area at Hazrat Shahjalal International Airport in Dhaka or at a customer center in town.

The local route gives you a Bangladeshi number and very cheap data, at the cost of a queue after a long flight and a SIM that expires with your tourist block. A travel eSIM skips the counter and the fingerprint scan, but carries data only. Compare the eSIM prices in the table below against what the counter quotes you on the day.

What an eSIM can't do for you in Bangladesh

The main limit is the phone number. Bangladesh's everyday services sign you in by SMS to a Bangladeshi number: bKash and Nagad mobile wallets, Pathao rides and food delivery, and many shop and bank checks. A data-only eSIM gives you no local number, so those accounts stay out of reach unless a local contact or a tourist SIM provides one. Uber works in Dhaka with your home number, and WhatsApp calls replace most voice calls.

• No local number: bKash and Nagad wallets, and many app sign-ups, verify you through a Bangladeshi SIM
• Sharing data with a laptop or a second phone in Dhaka depends on the plan's hotspot terms
• A phone locked to your home carrier won't take the Bangladesh profile; ask for an unlock before you fly to Dhaka
• Coverage thins in the Sundarbans, on the river chars and in the Chittagong Hill Tracts, whichever network you use

Dhaka, Sreemangal, Sylhet and Cox's Bazar: data for a two-week loop

A typical first visit combines Old Dhaka and a river trip on the Buriganga, the tea estates of Sreemangal, the wetlands around Sylhet and a few days on the beach at Cox's Bazar. On that route you lean on data for Google Maps in Dhaka's traffic, Uber between neighborhoods, WhatsApp with guides and guesthouses, and train or bus times between cities.

Count on roughly 300 to 500 MB a day for maps, messaging and social media, and more if you post video or make video calls. Two weeks of that lands around 5 to 8 GB, which a mid-size capped plan from the table covers; if you work from your laptop or stream, an unlimited plan avoids counting. Hotel Wi-Fi in Dhaka and Cox's Bazar is fine for large downloads, while guesthouses in the tea country are less predictable.

Signal along the delta: Sundarbans boats and the Hill Tracts

Bangladesh is densely populated, so 4G follows people almost everywhere a visitor goes: Dhaka, Chattogram, Sylhet, Khulna, Rajshahi and the hotel strip at Cox's Bazar. The exceptions are the places without towns. On a multi-day Sundarbans boat trip from Khulna or Mongla, expect long stretches with no signal once you are inside the mangrove forest. In the Chittagong Hill Tracts, Bandarban and Rangamati towns are covered but the hill roads and lakeside villages are not.

Download Google Maps offline for Dhaka and your route before you leave, and keep tickets and bookings as screenshots, so a gap in coverage never leaves you stuck.

Best eSIM plans for Bangladesh

Bangladesh is a very affordable data market, so eSIM prices are low and allowances go a long way. Simsima runs on the local networks with transparent pricing. Here is how a light 1 GB pack compares across eSIM providers:

If you would rather not track your usage, Bangladesh also has unlimited-data eSIMs, with speed reduced after a daily high-speed allowance until the next day. Here is how the unlimited plans compare:

Simsima's full Bangladesh lineup runs from small packs up to larger monthly allowances on the local networks. Because data is cheap here, a 3 to 5 GB plan comfortably covers most trips, with more for longer stays or remote work.

How to install your Bangladesh eSIM

Installation takes a couple of minutes and is best done at home on Wi-Fi before you fly, and it sidesteps the in-person registration required for local SIMs. The plan activates on its own when it connects to a local network on arrival.

1. Buy your Bangladesh plan on Simsima and open the confirmation with your QR code
2. On your phone, go to Settings, then Mobile or Cellular Data, and choose Add eSIM
3. Scan the QR code or use the one-tap install link, then label the plan Bangladesh
4. Keep your home line as default for calls and texts, and set the eSIM for data
5. Turn on data roaming for the eSIM line only, then land in Dhaka and go online

Adding India, Nepal or Sri Lanka to the trip

Many visitors arrive in Bangladesh from Kolkata or continue to Nepal. If your trip crosses borders, compare a single-country plan for each stop with a regional Asia plan, which uses one profile for all the countries in its zone; the regional guide below explains how the zones work.
