Stay Connected in Antigua and Barbuda
Network coverage, costs, and options
Connectivity Overview
Staying connected in Antigua and Barbuda is straightforward, with decent mobile coverage across both islands and reliable internet in tourist areas. The main carriers provide good 4G coverage in populated areas, though you might experience slower speeds in remote locations. Most hotels and restaurants offer Wi-Fi, but it can be inconsistent outside of resorts. For travelers who need reliable connectivity, having your own mobile data is essential. The country uses GSM networks, so most international phones will work here. Airport and resort areas have the strongest signals, while some rural areas and smaller beaches may have spotty coverage. Planning ahead for connectivity is smart since options at the airport can be limited.

We recommend Airalo for peace of mind. Buy your eSIM now and activate it when you arrive—no hunting for SIM card shops, no language barriers, no connection problems. Just turn it on and you're immediately connected in Antigua and Barbuda.
Network Coverage & Speed
Antigua and Barbuda's mobile infrastructure is served primarily by APUA (Antigua Public Utilities Authority) and Digicel, both offering 4G LTE coverage across most populated areas. Coverage is strongest in St. John's, the airport area, and major resort zones along the coast. Digicel generally provides better coverage on the more remote parts of both islands, while APUA offers competitive speeds in urban areas. 4G speeds typically range from 10-50 Mbps in good coverage areas, dropping to 3G (1-5 Mbps) in rural locations. Barbuda has more limited coverage than Antigua, with some dead zones in the interior. The networks use standard GSM frequencies (850/1900 MHz), compatible with most international devices. Wi-Fi is widely available in hotels and restaurants, but quality varies significantly. Cruise ship areas and the airport generally have the most reliable connectivity infrastructure.
How to Stay Connected
eSIM
eSIM is increasingly the smartest choice for Antigua and Barbuda, offering immediate connectivity without hunting for SIM cards at limited airport shops. You can activate service before landing and start using data immediately upon arrival. Providers like Airalo offer Caribbean regional plans that work across multiple islands if you're island-hopping. Typical eSIM costs range from $15-30 for 1-3GB valid for 7-30 days, which covers most vacation needs. The main advantages are convenience, security (no risk of losing your home SIM), and instant activation. You'll avoid language barriers and limited airport hours that can complicate local SIM purchases. The slight cost premium over local SIMs is usually worth it for the peace of mind and time saved, especially since you're likely only staying a week or two.
Local SIM Card
Local SIM cards are available from APUA and Digicel, typically costing $10-20 for the SIM plus $15-25 for 2-4GB of data. You can buy them at the airport (limited hours), carrier stores in St. John's, or some hotels. You'll need your passport for registration, and activation can take 15-30 minutes. Digicel shops are more common and offer tourist-friendly packages, while APUA may have slightly better rates but fewer locations. The main challenge is finding open shops outside business hours and dealing with potential language barriers during setup. Top-up cards are widely available at convenience stores and gas stations. If you're staying over a month or need large amounts of data, local SIMs offer better value. However, for typical vacations, the hassle often outweighs the modest savings.
Comparison
eSIM wins on convenience and immediate connectivity, costing about 20-40% more than local SIMs but saving hours of hassle. Local SIMs offer the best rates for heavy data users or long stays but require time to purchase and activate. International roaming is expensive ($10-15/day) and should be avoided except for emergencies. For most week-long vacations, eSIM provides the best balance of cost, convenience, and reliability.
Our Recommendations
First-time visitors: Go with eSIM from Airalo - you'll land with working data, avoid airport queues, and can research/navigate immediately. The convenience factor is huge when you're unfamiliar with the area. Budget travelers: If you're on an extremely tight budget, local SIM saves $10-15, but factor in the time cost and potential frustration. For most budget-conscious travelers, eSIM's convenience justifies the small premium. Long-term stays (1+ months): Local SIM makes financial sense for extended stays, offering better rates and easier top-ups for heavy usage. Business travelers: eSIM is essential - you need immediate connectivity for emails, calls, and navigation. The time saved and guaranteed working connection from landing makes it the only sensible choice for professional travel.

Purchase your eSIM before your trip and activate it upon arrival—you'll have instant connectivity without the hassle of finding a local shop, dealing with language barriers, or risking being offline when you first arrive.
