eSIM for Antigua and Barbuda

eSIM, roaming or a local SIM

There are three main ways to get online in Antigua and Barbuda. Each has trade-offs, and the right choice depends on how long you stay and how you use your phone.

How much data to plan for

Beach holidays tend to use less data than city trips, but sharing photos and making video calls home add up. Approximate figures:

• Maps: a few megabytes per hour; useful for finding beaches and restaurants down unmarked roads.
• Messaging: light; many taxi drivers, boat operators and villa hosts communicate by WhatsApp.
• Photos and social media: moderate to heavy, especially with video.
• Video calls: typically several hundred megabytes per hour.
• Streaming: heavy, often a gigabyte or more per hour in high definition.

Before you go

Installing an eSIM needs an internet connection, so do it at home on Wi-Fi. First check your phone supports eSIM and is carrier-unlocked.

Then follow the install guide for iPhone, Samsung or Pixel. Label the line clearly, keep your home SIM as default for calls and texts, and select the Spidot line for mobile data when you arrive.

• Install the eSIM a day or two before travelling.
• Download an offline map of Antigua, and of Barbuda if you are going there.
• Save your accommodation address and booking details offline.
• Turn off data roaming on your home SIM before you arrive.

Arriving in Antigua

Most visitors fly into V.C. Bird International Airport in the north-east of Antigua, a short drive from St John's. Many others arrive by cruise ship at the port in St John's, or by yacht at English Harbour, Falmouth Harbour or Jolly Harbour.

When you arrive, select the Spidot line for mobile data and turn on data roaming for it. Our data roaming guide explains where the setting is. If you do not connect within a minute or two, switch flight mode on and off once.

Coverage on Antigua and Barbuda

On Antigua, mobile data generally works well around St John's, the airport, the main resort areas and the harbours in the south. The island is hilly in the south-west, around Boggy Peak, and some beaches sit in coves below headlands, so you may find weaker signal in places. In Antigua and Barbuda, the Spidot eSIM connects to Flow.

Barbuda is much less populated. Expect coverage around Codrington, the main settlement, and weaker or no signal on remote beaches and in the lagoon. Plan your day there with offline maps and confirm pick-up times with your guide or driver before you set off.

• St John's and the north coast: busy areas that are usually well covered.
• English Harbour and Shirley Heights: usually covered; the evening gatherings at Shirley Heights can be busy, so the network may be slower then.
• Half Moon Bay and the east coast: quieter and more exposed to the Atlantic; signal may vary.
• Barbuda: coverage near Codrington; gaps elsewhere.

Getting around with data

On Antigua, taxis are the most common way for visitors to get around. Fares are often set by route; confirm before you set off. Local buses run from St John's to many villages, but they follow their own rhythm, so a map and a bit of patience help. Many visitors rent a car; driving is on the left, and roads can be narrow and potholed in places.

A navigation app is useful for finding beaches and restaurants, which are often down side roads with few signs. Download Antigua offline before you set off.

Sharing data with a hotspot

Villas, yachts and smaller hotels may have limited Wi-Fi. Your phone's personal hotspot can connect a laptop or tablet. It shares the line selected for mobile data, so make sure that is the Spidot line.

On a yacht, a hotspot is a handy way to give the whole crew access to weather forecasts and messaging while at anchor within range of land. Pause automatic updates and backups on connected devices to save data.

Using public Wi-Fi safely

Resorts, marinas, cafés and the cruise terminal area often have Wi-Fi. It is convenient, but open networks can be insecure.

• Use your eSIM data for banking and payments.
• Confirm the exact network name with staff before connecting.
• Turn off automatic joining of open networks.
• Keep your phone and apps up to date.

Practical tips for Antigua and Barbuda

A few local details worth knowing:

• Currency: the Eastern Caribbean dollar (XCD) is the local currency, and US dollars are widely accepted. Cards are accepted at most hotels and many restaurants; carry some cash for taxis, markets and beach bars.
• Sunday at Shirley Heights: the Sunday evening music gathering is a well-known tradition; arrange your taxi back in advance.
• Sailing events: Antigua Sailing Week and other regattas bring many visitors to English Harbour; book accommodation and taxis early.
• Beaches: some beaches are quiet with few facilities; bring water, shade and a charged phone.
• Heat and water: keep your phone out of direct sun and use a waterproof pouch on boats.
• Hurricane season: the Atlantic hurricane season runs from June to November. Data helps you follow weather updates and airline messages.

Antigua and Barbuda on a multi-island trip

Antigua is a hub for island-hopping in the Leewards. Common combinations include St Kitts and Nevis, Anguilla, Montserrat, Guadeloupe and Dominica, by ferry, small plane or yacht.

Install one eSIM per destination before you leave home. Most eSIM phones store several, and you switch mobile data to the right line when you arrive. Islands can be close enough that your phone picks up a neighbouring network, so check the network name after each crossing.
