Andros, the Bahamas’ largest island by land area, is also among its least densely populated — a haven for divers drawn to its famous blue holes and bonefishing enthusiasts, with connectivity reflecting the island’s sparse settlement pattern more than its considerable size.
Quick answer: Coverage on Andros concentrates around its main settlements, generally more limited than smaller but more developed Out Islands like Exuma or the Abacos, given how thinly Andros’s population is spread across its large landmass.

Why Andros has more limited coverage despite its size
Mobile infrastructure follows population density rather than land area, and Andros’s large size combined with a genuinely sparse population means less justification for extensive network buildout compared to smaller, more densely settled islands, similar to the pattern covered in the Out Islands coverage guide.
Coverage around main settlements
Andros’s main towns maintain workable coverage, generally from BTC given its established rural presence — the best network for tourists guide covers this comparison in more depth, and the best SIM card guide covers choosing between BTC and Aliv more broadly.
Diving and blue holes
Andros’s famous blue holes and dive sites, a major draw for underwater exploration, often sit away from main settlements, and coverage at these specific locations is generally limited to nonexistent — treat a diving day here as intentionally offline time, similar to the offline stretches covered in the Exuma Cays guide for another remote Bahamian attraction.
Bonefishing lodges
Andros’s renowned bonefishing scene draws visitors to lodges often situated in quieter, more remote parts of the island — connectivity at a specific lodge varies, and checking directly with your accommodation about their WiFi or nearby coverage is worth doing before you arrive, covered further in the beyond resort WiFi guide.
The AUTEC facility
Andros is also home to a US Navy testing facility, a notable feature of the island’s geography though not something that affects tourist connectivity directly — worth knowing as background context rather than a practical consideration for most visitors.
Getting connected before you arrive
Given Andros’s more limited infrastructure, installing an eSIM before you fly, or setting up a SIM in Nassau first via the Nassau airport SIM guide, is generally more practical than expecting extensive registration options on the island itself.

Varies by lodge — check directly with your accommodation before arriving.
Why is Andros less covered despite being the largest island?
Mobile infrastructure follows population density, and Andros is sparsely populated relative to its size.
Should I set up connectivity before arriving on Andros?
Yes, given the island’s more limited local registration infrastructure.
Which network is best for Andros?
BTC generally, given its established rural presence across the Out Islands.
Final Recommendation
Set up connectivity before you arrive, and treat diving and remote lodge stays as likely offline experiences. See the Out Islands coverage guide for the wider regional picture.
