There is not much choice for tourists that are traveling to Antigua & Barbuda. Unfortunately there are not many e-sim cards for Antigua & Barbuda available on the internet. And when it comes to buying a prepaid sim card there are only 2 mobile operators and few stores. And like most other things in Antigua & Barbuda, a prepaid sim card for tourists with data it is NOT cheap.

Although most hotels and resorts in Antigua have ok WiFi, I would still advice you to buy a sim card for Antigua. That way you can always rely on 4G and you won’t have any problems with streaming videos for example. The WiFi in the luxury resorts I stayed at was not strong enough to stream live football for example and on the deserted Antigua beaches there is no wifi signal of course.

Also when road tripping and going to some of the best places to visit in Antigua & Barbuda being connected to Google Maps for directions and finding local restaurants gets much easier when you have data on your phone. Buying a sim card for traveling to Antigua & Barbuda is therefore very much recommended!

Getting a sim card on arrival in Antigua & Barbuda is rather time consuming and expensive. There is a much better option and that is to order one online before your trip or to get an e-sim card for Antigua & Barbuda. Check out my article with the best sim cards for traveling the world in 2023.

At Antigua Airport on arrival I found an INET Mobile sim card, but I can already tell you that buying this tourist sim card at Antigua Airport is not a good idea! More about it later.

Best mobile data network in Antigua & Barbuda

Normally I would take the network coverage for Digicel and Flow into consideration to find out what is the best sim card in Antigua & Barbuda. Imagine finding a great sim card deal but then finding out there is hardly is any phone reception.

For Antigua and Barbuda it was a little harder to find relevant information about the network strength on the island for Flow and Digicel. As you can see in the picture above Flow is claiming to have the most reliable 4G network in Antigua, but I asked the locals to find out more.

According to locals Digicel has the best 4G network in Antigua, but it doesn’t differ much from Flow apparently. Based on my own experience I can tell you that Flow has a good 4G network. I bought a FLOW sim card in Antigua and it worked perfectly fine. Most tourist spots in Antigua I visited I had a good 4G data connection.

As of August 2023 there is no 5G data connection available in Antigua & Barbuda, the fastest mobile data connection is 4G/LTE.

Where to buy a sim card in Antigua

Buying a sim card in St. John’s city center

The best place to buy an Antigua sim card is in St. John’s. In the city center of Antigua's capital you will find a Digicel and a Flow shop only about 1 block away from each other. Both shops are located in Market Street and easy to locate. In both the Digicel and Flow shop you can pay with international credit cards.

The problem is that it can be very busy and you will need to wait in line to for a while until it is your turn. This is the main reason why I recommend you to get an e-sim card for Antigua & Barbuda or an international sim card with coverage in the Caribbean.

Buying a sim card at Antigua Airport

Unfortunately there is no Flow or Digicel shop at Antigua Airport (ANU). That said it is still possible buying an Antigua sim card at the airport. Right behind customs (before baggage claim) there is a duty-free shop and they sell INET Mobile sim cards.

It is the easiest way to buy a sim card when arriving in Antigua, but also the most expensive one! The INET Mobile sim card cost $30 USD and gives you only 1GB data. Super expensive!

Important! For buying an Antigua sim card you will need a photo ID, passport is best, but I bought my Flow sim card with my Dutch drivers license.
