Choosing a SIM for the Bahamas really comes down to two decisions — which of the two networks to use, and whether a physical SIM or an eSIM suits your trip better — and the right answer depends mostly on which islands you’re actually visiting.
Quick answer: BTC has the widest reach, particularly into the Out Islands, making it the safer default if your trip goes beyond Nassau or Freeport. Aliv is a strong, often competitively priced choice if you’re staying on New Providence or Grand Bahama specifically.

BTC (Bahamas Telecommunications Company)
BTC is the Bahamas’ longest-established network, with the most extensive coverage extending into the Out Islands — the mobile networks in the Bahamas guide covers this in more depth, and BTC is generally the recommended choice for any itinerary beyond the two main islands.
Aliv
Aliv, launched by Cable Bahamas as a newer competitor, offers strong coverage and often competitive pricing on New Providence and Grand Bahama specifically, though its reach into the more remote Out Islands is more limited than BTC’s — a good choice if Nassau or Freeport is your whole trip.
Coverage comparison
On Nassau and Freeport, both networks perform well enough that the choice matters less. Once you’re island hopping or visiting the Out Islands, BTC’s longer-established rural infrastructure becomes the more important factor — the best network for tourists guide covers matching a network to your specific itinerary.
Registration and buying process
Both networks require ID or a passport for prepaid SIM registration, available at either main airport or at shops throughout Nassau and Freeport — the buying a SIM at Nassau Airport guide and buying a SIM at Grand Bahama Airport guide cover this process specifically.
Price and bundle differences
Pricing between BTC and Aliv is broadly comparable, with occasional promotional differences — the bigger factor for most trips is coverage extent rather than a small pricing gap, especially once Out Islands are part of your itinerary. See the mobile data guide for typical bundle options.
Physical SIM or eSIM instead?
If you’d rather skip in-person registration, a travel eSIM covering the Bahamas typically runs on one of these same two underlying networks — the local SIM vs eSIM guide covers the trade-offs between the two approaches.
