Planning a trip to Antigua and Barbuda and wondering what is the best SIM card for tourists in 2026? This is my complete guide to buying a prepaid SIM card in Antigua as well as the best eSIM options to stay connected.

I spent about a week traveling around Antigua and quickly realized that once you leave your hotel or resort, reliable internet is not always guaranteed. Whether you are navigating between St. John’s and English Harbor or hunting down the island’s most beautiful beaches, having mobile data makes traveling around Antigua a lot easier.

If you are still planning your trip, check out my Antigua travel guide for more tips and inspiration.

That is why I recommend getting either a local prepaid SIM card or an eSIM for Antigua and Barbuda. In this guide I compare both options, show you where to buy a SIM card, how much it costs and what is the best option for your trip.

Welcome to Antigua & Barbuda, welcome to the country with 365 beaches. Recently I boarded a plane in London for my direct flight to the enticing island in the Caribbean: Antigua & Barbuda. A week long I was able to explore the best Antigua tourism has to offer. It was my first time visiting, a country many people most probably never heard of, but since I was a kid I was in love with their flag. Finally I got the chance to travel to Antigua myself!
