The Exumas draw visitors specifically for their stunning turquoise water, the famous swimming pigs, and a popular boating and yacht charter scene — connectivity here centers on Georgetown, the main town, with more variable signal across the scattered cays further out.
Quick answer: Georgetown has workable 4G coverage from BTC and, to a lesser extent, Aliv. Once you’re out among the cays — visiting the swimming pigs at Big Major Cay or Thunderball Grotto — expect coverage to thin considerably, since these are remote, largely undeveloped stretches of water and small islands.

Coverage in Georgetown
Georgetown, Exuma’s main settlement, has reasonable 4G coverage supporting typical needs — maps, messaging, browsing — though it’s noticeably less dense than Nassau or Freeport given the town’s smaller size.
Coverage among the Exuma Cays
The scattered cays north of Georgetown, including the area around the famous swimming pigs and Thunderball Grotto, have limited to no coverage away from Georgetown itself — the Exuma Cays mobile internet guide covers this in more depth for anyone planning a boat trip through this specific area.
Choosing a network for Exuma
BTC generally has the more established presence in Exuma given its wider Out Islands reach — the best network for tourists guide covers this comparison, worth taking seriously if your Exuma trip involves boating between cays, and the best SIM card guide covers the fuller BTC vs Aliv picture.
Boat charters and day trips
Many visitors experience the Exumas via a chartered boat trip covering several cays in a day, and connectivity during this kind of trip follows the general pattern of strong signal near Georgetown fading to nothing further out — planning to be offline for stretches of a boat tour is realistic rather than pessimistic, covered further in the marina mobile internet guide.
Getting connected before you arrive
Since Exuma’s airport has more limited SIM registration infrastructure than Nassau or Freeport, installing an eSIM before you fly, or getting a SIM sorted in Nassau first if you’re connecting through there via the Nassau airport SIM guide, is worth considering.
Downloading maps and information in advance
Given how quickly coverage drops once you’re away from Georgetown, downloading offline maps and any information about specific sites you’re visiting removes the guesswork for a day on the water — the Google Maps in the Bahamas guide covers setting this up properly.

Final Recommendation
Get connected before you arrive given Exuma’s more limited airport infrastructure, and expect coverage to thin considerably once you’re out among the cays. See the Exuma Cays guide for boat trip specifics.
