The best eSIM for Bangladesh depends on how much data you need, but for a typical trip eSIM Ahora offers plans from $1.44, activated by QR code in about 30 seconds with no roaming from your home carrier. A 3 GB, 30-day plan costs $5.06. You connect, with top-ups available and nationwide coverage. Compatible with iPhone XS or newer, Samsung Galaxy S21+ and Google Pixel 3+.
Full-speed data every day; after the daily cap the speed is reduced.
Full speed up to 500 MB/day, then 512 Kbps.
Every eSIM can be installed within 180 days of purchase. Plan validity starts when you first connect.
Your eSIM picks between these networks on its own. If you see bars and nothing loads, you can pick one by hand.
Your Bangladesh eSIM runs on one network: Banglalink. Other local networks won't carry your data: if you see signal bars and nothing loads, turn off automatic network selection (iPhone: Settings → Cellular → your eSIM → Network Selection; Android: Settings → Network & internet → SIMs → your eSIM) and pick Banglalink by hand.
Bangladesh has three main carriers: Grameenphone (Telenor subsidiary, largest nationwide coverage, 5G in Dhaka and Chattogram), Robi (broad urban 5G), and Banglalink (Veon subsidiary, best rural value). Plugs are Types C, D, and G (British and Indian mix), 220V — use a universal adapter. 4G reaches Dhaka, Chattogram, Sylhet, Khulna, and most of the rail network, but the Sundarbans delta has no-signal zones.
Dhaka Hazrat Shahjalal Airport (DAC) offers limited free WiFi. The currency is the taka (BDT, non-exportable — spend before leaving). Use Standard Chartered, HSBC, and Citibank N.A. ATMs to avoid tourist commissions. Visa on arrival costs USD 51 (e-visa cheaper). Tips are 5-10%. Bangladesh is Muslim but Western apps work. Watch traffic in Dhaka — Uber and Pathao (local) are the safest option. For Cox's Bazar (the world's longest beach, 120 km) coverage is full in the hotel zone.
