 Yes, Google Maps works well across the island. Reliable data is essential for navigating the winding roads to English Harbour or remote beaches. 

 Yes, coverage is excellent at Shirley Heights Lookout. You can livestream the famous Sunday sunset parties without buffering. 

 Signal is strong at the docks but may drop temporarily in the middle of the open ocean crossing between St. John's and Barbuda. 

 Yes, the 4G LTE network in Antigua and Barbuda is stable enough for clear WhatsApp or FaceTime calls to home. 

 Coverage is generally good at popular spots like Dickenson Bay, but signal may drop to 3G at secluded spots like Rendezvous Bay. 

 No, the islands primarily rely on a robust 4G/LTE network. 5G is not yet standard across Antigua and Barbuda. 

 Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing. 

 Scan it at home before your flight. This ensures you get immediate data the moment you land at V.C. Bird International Airport (ANU) without searching for free WiFi. 

No! This is the #1 roaming trap. Antigua and Barbuda is an independent country and is NOT part of the EU, UK, or US domestic plans. Most home carriers (like AT&T, Verizon, T-Mobile, or UK's Vodafone/O2) will charge you expensive international "Day Pass" rates (e.g., $10-$15 per day). A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper. 

Yes, perfectly. This is the ideal solution for cruise passengers. Your cruise ship's Wi-Fi is satellite-based and expensive. The moment your ship docks in St. John's, your eSIM will connect to the local 4G network. This allows you to leave the port, use Google Maps (for your taxi), and upload your beach photos for the day. 

Yes, for mobility and privacy. Most luxury resorts (like Sandals) offer Wi-Fi, but it is often slow, shared with all guests, and only works in the lobby. A personal eSIM gives you a private, fast 4G/LTE connection that works everywhere—in your room, by the pool, and, most importantly, when you leave the resort to explore. 

 To give you the best speed and coverage on both islands, our eSIM connects to the premium local providers, typically Digicel or Flow. This ensures you get the fastest available 4G/LTE speeds for using Google Maps or making WhatsApp calls from your hotel. 

Yes, absolutely. This is the most important question for visitors. Our eSIM plan covers both islands with one single purchase. You can have a strong signal at Dickenson Bay (Antigua), take the ferry/flight, and stay connected on the pink sand beaches of Barbuda.
