Mobile data in the Bahamas is straightforward to buy and reasonably priced by regional standards, with BTC and Aliv both offering prepaid bundles sized for visitors — the more important consideration than price is usually which islands your data plan needs to actually cover.
Quick answer: Prepaid data bundles from BTC or Aliv, typically valid for a week or a month, cover most visitor needs on Nassau and Freeport comfortably. Pricing is quoted in Bahamian dollars, pegged 1:1 to the US dollar, and USD cash is accepted just as readily at most shops selling SIMs.

How prepaid bundles are structured
Both BTC and Aliv sell data bundles by volume and validity period, similar to prepaid plans anywhere — shorter, smaller bundles suit a quick visit, while larger or longer-validity options make more sense for an extended stay or a multi-island itinerary.
Pricing in Bahamian dollars vs USD
Since the Bahamian dollar is pegged 1:1 to the US dollar and both currencies circulate interchangeably, prices for data bundles are effectively the same whether quoted in one currency or the other — a genuinely simple aspect of budgeting for connectivity here compared to destinations with currency conversion to account for.
How much data you’ll actually need
Casual use — maps, messaging, browsing, occasional photo uploads — fits comfortably within a mid-sized weekly bundle. Heavier use, like video calls or streaming, benefits from checking the how much data guide for more specific sizing by activity, and the unlimited data guide covers a higher-tier option worth considering for consistently heavy use.
Topping up mid-trip
Bundles can typically be renewed through each carrier’s app, a USSD code, or in person at a shop — worth checking your balance before it runs out, particularly if you’re heading to an Out Island where top-up options may be more limited, a scenario covered further in the eSIM not working guide if a depleted bundle starts looking like a connectivity problem.
Data speeds on the main islands vs Out Islands
4G is standard on Nassau and Freeport, generally fast enough for typical browsing and streaming — the 4G and 5G in the Bahamas guide covers where faster speeds are available. The Out Islands coverage guide covers the more variable picture once you leave the two main islands.
Managing data during island hopping
Travelers moving between multiple islands on one trip should size their bundle generously and check coverage for each specific stop in advance — the island hopping guide covers planning connectivity across a multi-island itinerary.
