Stay Connected in Bangladesh

Bangladesh connectivity surprises travelers both ways. The good news first. Mobile data is cheap. Coverage across Dhaka, Chattogram, and Sylhet is solid, and 4G is standard in any town you'd realistically visit. The downsides are real too. Speeds can wobble during peak evening hours, SIM registration is stricter than most of South Asia, and rural coverage drops off fast (think the Sundarbans, the Chittagong Hill Tracts, or remote chars in the Padma delta). Hotel WiFi in Bangladesh is hit-or-miss outside the international chains, and power cuts still occasionally knock routers offline, even in Dhaka. Here's the catch most first-timers miss. Every local SIM requires biometric fingerprint registration, tourists included. Plan for that. You'll be online within an hour of clearing customs.

Bangladesh has four main mobile carriers worth knowing. Grameenphone leads the pack. The dominant player, best overall coverage, with strength in rural areas and along highways. Robi runs good urban 4G, popular with younger users, decent data bundles. Banglalink has competitive pricing, strong in Dhaka and Chattogram, sometimes spotty in the north. Teletalk is state-owned. Cheapest but patchier coverage, generally skip unless you're staying long-term. 4G LTE is widespread across all four in cities and most district towns. 5G has been trialled in pockets of Dhaka. Plan around 4G instead. Real-world speeds tend to land in the 15-40 Mbps range on 4G in Dhaka, dropping to 5-15 Mbps in smaller towns. Evening crunch hits hard. Speeds crawl during the 8-11pm window when everyone's streaming cricket or dramas. Grameenphone is the safe default if you'll travel beyond the main cities. That holds doubly if you're heading to Cox's Bazar, Sylhet's tea estates, or the Sundarbans buffer zones where Robi and Banglalink thin out noticeably.

Hotel WiFi in Bangladesh is convenient. But, as with most countries, it's not somewhere you want to log into your bank without a second thought. Airport and cafe networks in Dhaka and Chattogram are open and unencrypted by default. That means anyone on the same network can potentially see unencrypted traffic. Travelers are easy targets. They're juggling more sensitive logins than usual: hotel bookings, payment apps, work email, all in quick succession. A VPN like NordVPN encrypts your connection between your device and the VPN server. Even if someone's snooping on the cafe WiFi, they see scrambled data instead of your inbox. VPNs help in another way. They unblock services that geo-block Bangladesh IPs, which catches some travelers off guard with banking apps. Stick to mobile data for highly sensitive logins when you can.
