For travelers who need to stay connected, WiFi in Harbour Island is widely available. Hotels, restaurants, and vacation rentals ensure a strong, stable signal throughout their premises, making it easy to stay online anytime.

Wi-Fi is usually complimentary and businesses are pretty cool about it and provide you access.

The only issue, it is rare but it may happen, is when the city electricity service is being interrupted. When this happens your Wi-Fi will be interrupted even if the hotel or vacation rental that you are staying in has generators.
Some luxury vacation rental homes such as La Palmeraie Bahamas provides their clients with hotspots so they stay connected no matter what happens.

Be sure to ask the relevant questions to your hotel or your Harbour Island vacation rental agency.
