The Bahamas is one of the most expensive places in the world for travel eSIM data. On our measurements it is pricier per gigabyte than 167 of the 187 countries in our price index. That changes the advice: for many visitors, the best plan is a very small one — or none at all.
Short answer: for a cruise port day or a resort stay with WiFi, a 1GB plan is enough. Check first whether your home plan already covers the Bahamas, and on a cruise ship, never let your phone roam on the ship's network.
What a Bahamas eSIM costs
At the time of writing (October 2026), Wanderly's Bahamas plans start at $9.99 for 1GB (7 days). Larger allowances cost roughly $5–$8 per GB, and the median across data-only Bahamas plans is about $5.55 per GB — almost four times the $1.43 global median in the Wanderly eSIM Price Index.
In practice that means:
- 1Buy the smallest plan that covers your needs. Maps, messages and a ride booking fit in 1GB for a few days.
- 2Use resort and café WiFi for photo backups, video calls and streaming.
- 3Check your home plan. Some US plans include roaming in parts of the Caribbean; if yours does, you may not need an eSIM.
Cruise passengers: the real trap
Most visitors arrive by cruise ship at Nassau, Freeport or a private cruise island. At sea, phones can join the ship's maritime network, which is billed separately and very expensively by many home carriers.
- Turn off data roaming on your home line before the ship leaves port, and keep it off.
- Use the ship's WiFi package, or put the phone in airplane mode at sea.
- A 1GB Bahamas eSIM covers the port day itself. Our cruise connectivity guide explains which networks you are on at sea and in port.
Networks and coverage
The Bahamas has two networks, BTC and Aliv. Travel eSIMs connect to a partner network automatically.
- Nassau and Paradise Island: good 4G.
- Freeport (Grand Bahama): good.
- Exumas, Eleuthera, Abaco: coverage in settlements and resorts; weaker on remote cays and at sea.
- Private cruise islands: check coverage with your cruise line.

- 2Install the eSIM over WiFi before you travel — iPhone or Android steps.
- 3In port or on landing, select the eSIM for mobile data and turn on data roaming for that line.
