HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric overall for Antigua and Barbuda, with App 5.0 and Support 5.0 on an iOS and Android app, live chat plus WhatsApp, and a 180-day refund. Fixed plans start from $3.50/GB, the second-lowest fixed rate of the five for a trip across Antigua and Barbuda's two-island geography, with unlimited from $5. Its 204+ carrier partnerships matter less here, since FLOW and Digicel are the only two carriers enrichment data records for the country regardless of which provider sells the eSIM.

Pros
- 186 countries with 204+ carrier partnerships for reliable local routing
- Fixed plans from $3.50/GB across popular destinations

Is unlimited or fixed data better for a trip to Antigua and Barbuda?
HelloRoam leads the 2026 composite at 4.64/5 in our comparison matrix for Antigua and Barbuda. The country's unlimited-daily rate is $18.00 in this comparison's data, well above Holafly's $2.99/day rate and its 2GB fair-use threshold. HelloRoam also sells unlimited from $5.

Does coverage differ between Antigua and Barbuda, the two islands?
Enrichment data specifically flags good coverage on both islands making up the country, Antigua and the smaller Barbuda.

Does an eSIM need SIM or IMEI registration in Antigua and Barbuda?

Enrichment data records two emergency numbers for the country, 911 and 999, a wider set than the single 911 listing recorded for neighboring Anguilla. Both numbers work regardless of which of the five compared eSIM providers supplies the data connection, since emergency calling routes independently of a data plan.
