Frequently Asked Questions
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, 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.
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.
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.
Connect to any airport or hotel WiFi in Antigua and Barbuda and contact our 24/7 support via WhatsApp or Email immediately.
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.
About Antigua and Barbuda eSIM
Antigua and Barbuda eSIM for Your Travels
Stay connected with a Cellesim eSIM for Antigua and Barbuda. This digital SIM card provides you with mobile data right on your phone, so you can navigate with maps, share photos, and stay in touch without searching for Wi-Fi. Plans start from $10.96 and offer a reliable data connection from the moment you arrive.
Choosing Your Data Plan
Selecting the right plan depends on your trip's length and how you use your phone. We offer options to fit various travel styles, with validity periods ranging from a single day up to 30 days.
- For short trips or light use: If you're visiting for a day or two and mainly need data for maps and messaging, smaller plans like 500 MB or 1 GB are a great fit. These are ideal for weekend getaways or cruise ship stops.
- For week-long holidays: For a typical 7 to 10-day vacation, consider plans with 3 GB to 5 GB. This amount of data is usually sufficient for regular social media use, browsing, and using navigation apps without worry.
- For heavy users or long stays: If you'll be in Antigua and Barbuda for several weeks, work remotely, or use a lot of data for streaming and video calls, larger plans of 10 GB or 20 GB are more suitable. We also offer unlimited data plans for those who want maximum freedom, though speeds may be reduced after a certain amount of data is used.
Network and Coverage
Your eSIM will connect to the local network to provide a stable data service. In Antigua and Barbuda, our partner network is FLOW. You can expect good coverage in populated areas like St. John's, English Harbour, and major resort areas.
Please note that all our eSIM plans for Antigua and Barbuda are data-only. They do not come with a phone number and cannot be used for traditional cellular calls or SMS texts. However, you can easily make voice and video calls using internet-based apps like WhatsApp, FaceTime, Skype, or Telegram over your data connection.
Traveler's Tips for Staying Connected
While network coverage is strong in towns and tourist centers, you might find it becomes less consistent in more remote rural areas of Antigua or on the less-populated island of Barbuda. It's a good practice to download offline maps for any areas you plan to explore off the beaten path. Using your own secure data connection from an eSIM is also a safer alternative to potentially unsecured public Wi-Fi networks in cafes or hotels.
Your eSIM works alongside your primary SIM card. This allows you to keep your home phone number active for services like iMessage or WhatsApp, and you can still receive calls and texts on your regular number (roaming charges from your home provider may apply). You simply use the Cellesim eSIM as your designated line for mobile data.
Easy Installation in 3 Steps
Setting up your eSIM is straightforward and can be done before you leave home.
- Step 1: After purchase, follow the instructions to install the eSIM profile onto your compatible device. You will need a stable Wi-Fi connection for this step.
- Step 2: When you land in Antigua and Barbuda, go into your phone's cellular settings and turn on your Cellesim eSIM line.
- Step 3: Make sure to enable Data Roaming for the eSIM line to begin using your data. The validity period of your plan may start at installation or upon first connection to the network; please check the details of your specific plan.
