Best eSIM for Bangladesh (2026): Plans, Prices & Coverage

Grameenphone, Robi, and Banglalink all require biometric fingerprint registration tied to your passport before a local SIM works, with no exception for visitors — so for most trips to Bangladesh, a data-only eSIM (an embedded SIM profile installed digitally, with no physical card to register) like co:sim's is the faster path to a working connection. This guide compares Bangladesh eSIM data plans by validity and data amount, checks how the four operators actually perform outside Dhaka, and walks through getting set up before you land.

#What to look for in a Bangladesh eSIM

Four things decide whether a Bangladesh eSIM is worth buying: which local network it rides on, how much data and validity you actually need, whether it supports a top-up if your trip runs long, and price per gigabyte rather than the headline number. Grameenphone leads the country with roughly 87 million subscribers, well ahead of Robi and Banglalink, but subscriber count alone doesn't tell you which network reaches the beach town or hill district you're actually headed to — that's a coverage question, covered below.

Data-only eSIMs don't include a Bangladeshi phone number, which matters if you're expecting a callback from a hotel or a ride-share driver — WhatsApp, Messenger, and other data-based calling and texting work fine over any of these plans. Validity length matters as much as data volume: a plan sized for a five-day Cox's Bazar weekend is a poor fit for a three-week trip covering Dhaka, Sylhet, and the south, so check the number of days as closely as the gigabytes.

International eSIM marketplace apps also sell Bangladesh data plans, and they're a reasonable option if you're already using one for other stops on a longer regional trip. The trade-off is usually price per gigabyte on a single-country plan, since a marketplace app prices Bangladesh as one of dozens of destinations rather than optimizing for it specifically, so it's worth comparing against a Bangladesh-focused plan on your own itinerary rather than assuming either is cheaper by default.

#Bangladesh eSIM plans compared

Bangladesh's tourist-SIM reform has made the local options genuinely usable for some travelers, so the honest comparison is between three real paths rather than a co:sim-versus-nothing pitch:

co:sim's plan page for Bangladesh lists the current data tiers, validity, and price before you buy, so there's a real figure to check against your itinerary instead of a vague range. Every plan is prepaid and data-only, and reloadable plans can be topped up from the same account if a trip runs longer than expected. If Bangladesh is one stop on a wider regional trip, co:sim's Central and South Asia plan covers several countries on a single eSIM instead of buying a separate plan at each border.

#Network coverage and speeds in Bangladesh

National 4G coverage claims to reach nearly the whole population, but performance away from Dhaka and Chattogram still varies sharply by operator. Opensignal's January 2026 Bangladesh report measured rural 4G availability at 75% for Grameenphone, versus 65% for Robi and 58% for Banglalink — a real gap once your trip goes beyond the capital. Grameenphone and Robi both switched on commercial 5G in September 2025, though so far only in divisional headquarters and select city zones, so 5G isn't a realistic factor for most tourist itineraries yet.

That gap matters most for regional destinations: Cox's Bazar and Sylhet both sit outside the two biggest cities, so which network your eSIM rides on affects your day-to-day experience more there than it would in central Dhaka, where all four operators are strong. The Sundarbans mangrove forest is the honest exception worth naming directly — signal from any operator thins out fast once you're deep in the reserve, so don't plan on a reliable connection there regardless of which eSIM you're carrying.

#How to set it up before you land

1. Buy your Bangladesh eSIM online before you fly — co:sim emails the QR code within seconds of checkout, so there's no airport queue to join.
2. Install it on hotel or home Wi-Fi a day or two before departure: Settings → Cellular → Add eSIM on iPhone, or Settings → Network & internet → SIMs → Add eSIM on most Android phones.
3. Leave your home line as the default for calls and texts, and set the new eSIM as the data line, so nothing about your existing number changes mid-trip.
4. Turn on data roaming for the new eSIM specifically once you land, and confirm you've picked up a Bangladeshi network in the status bar before you start browsing.
5. If the eSIM doesn't pick a network automatically, select one manually under Settings → Cellular → Network Selection (iPhone) or your Android's equivalent SIM settings, rather than waiting on automatic selection, which can be slow the first time a profile roams.
6. If your plan is reloadable and you're running low, top up from co:sim's account dashboard rather than hunting for a local recharge counter.

#FAQ

#Do I need a passport to buy an eSIM for Bangladesh?

No — that's the main practical difference from a local SIM. Buying a physical SIM from Grameenphone, Robi, or Banglalink requires showing your passport in person and completing a biometric fingerprint scan at the carrier's own store, with no exception for tourists; the SIM is then tracked on Bangladesh's Central Biometric Verification Monitoring Platform before it activates. A data-only eSIM like co:sim's works differently: you buy it online before you fly, receive the QR code by email, and install it on your own phone, so there's no in-person registration step, no fingerprint scanner, and no local agent involved on the Bangladesh side at all. You still carry your passport for immigration control at the border, of course — the difference is that a SIM purchase no longer requires showing it to anyone.

#Can tourists still buy a regular local SIM in Bangladesh?

Yes, but expect the full registration process: passport, one or two passport photos, and a fingerprint scan at a carrier's own store, since resellers can't register a SIM under their own ID and informal booths outside official stores often handle registration badly. Bangladesh has also rolled out a dedicated tourist SIM, sold at airport and land-, sea-, and port-of-entry kiosks in 7, 15, or 30-day validity blocks and capped at two SIMs per passport, with an on-arrival eSIM option available through the same system. Either path still means handing your passport to a local agent and sitting through a biometric check that can take 15-20 minutes when the kiosk's scanner is working, longer when it isn't — a step a pre-installed eSIM skips entirely by never touching a Bangladeshi retailer in the first place.

#Which network is best for Cox's Bazar or Sylhet?

Grameenphone posts the strongest rural 4G availability nationally at 75%, per Opensignal's most recent measurement, well ahead of Robi at 65% and Banglalink at 58% — a gap that tends to carry over to popular regional destinations like Cox's Bazar and Sylhet better than it does for the other two operators outside Dhaka and Chattogram. That doesn't make Grameenphone automatically the right pick for every eSIM plan, since price, data amount, and validity still matter as much as network strength for most trips. It's worth checking which local network a specific eSIM plan actually rides on before buying if your itinerary is regional-heavy rather than Dhaka-based, since the performance gap between operators widens noticeably the further you travel from the two biggest cities.

#Does eSIM data work everywhere in Bangladesh, including the Sundarbans?

Not reliably in the Sundarbans specifically. National 4G coverage is strong in cities and most towns, with 4G reportedly reaching close to the whole population on paper, but the Sundarbans mangrove forest is genuinely remote terrain, and signal from any Bangladeshi operator, not just eSIM providers, drops off fast once you're away from its edges and deep into the reserve itself. This is true regardless of which network your eSIM or local SIM uses, since it's a physical infrastructure gap rather than a carrier-specific weakness. Plan for offline stretches there rather than expecting continuous data. Download offline maps and any documents you need before entering the reserve, and don't count a patchy Sundarbans connection against the eSIM itself when the same gap would affect a local SIM too.

#Can I buy a Bangladesh SIM at Dhaka's airport instead?

Yes — Hazrat Shahjalal International Airport in Dhaka has SIM kiosks for arriving passengers, and it's one of the official ports of entry where Bangladesh's new tourist SIM can be registered on the spot, including the on-demand eSIM option the same system offers. The trade-off is the same one any arrivals-hall kiosk carries anywhere in the world: a queue after a long flight, a fixed choice between 7, 15, or 30-day tourist-SIM validity blocks rather than a plan sized to your exact trip length, and a biometric registration step before the SIM activates. Smaller regional airports and land border crossings have less consistent kiosk availability and staffing than Dhaka's main airport, which is exactly where a pre-installed eSIM removes the variable entirely, since it's already working before you even board your flight.

#Is a Bangladesh eSIM data-only, or does it include calls and texts?

Data-only, which is standard for travel eSIMs including co:sim's Bangladesh plans: you get mobile data with no Bangladeshi phone number attached to the plan at all. Calls and texts over apps like WhatsApp, Messenger, or Viber work normally on that data connection, so most travelers don't notice the difference day to day. What you actually lose is a local number for SMS verification codes, a callback from a taxi or ride-share driver, or a hotel confirming your booking by phone — situations where a business specifically needs to dial a Bangladeshi number rather than message you. If any of those matter for your trip, some travelers carry a cheap local SIM for that one purpose while keeping the eSIM as their main data connection.

#What happens if I need more data mid-trip?

If you picked a reloadable co:sim plan, you can top up directly from your account dashboard without needing a Bangladeshi payment method, a local currency, or a trip to a physical recharge counter — the same convenience that made installing the eSIM easy in the first place carries over to extending it. Check whether a specific plan supports top-ups on its product page before you buy if you expect your data needs to grow partway through the trip, since not every plan tier is reloadable, and some are sized as a fixed one-time allowance for a specific trip length instead. If your current plan isn't reloadable and you run out, buying a second plan works as a fallback, though sizing the original purchase correctly is usually simpler.

Install a co:sim eSIM before you fly, and Dhaka's SIM registration queue becomes someone else's problem the moment you land.
