Coverage in Antigua and Barbuda

Common Questions

The details worth knowing about your Antigua and Barbuda eSIM

No. Mobile coverage on Barbuda is limited outside Codrington village. In some outlying areas, Digicel’s network is only 3G. Your eSIM may still connect near Codrington, but don’t rely on data speeds or coverage across the island.

No. This eSIM provides coverage only within Antigua and Barbuda. If you cross into the waters or land of other Caribbean territories, you will need a separate data plan for that country.

That depends on your eSIM provider and your phone. Flow operates 4G on bands B2, B4, B5, B12, B17 and 5G on n5, n66. Digicel uses 4G on B2, B4, B5, B8, B12 and 5G on n66. Your device will pick whichever network is available and compatible.

Possibly. Flow uses B12 and B17 (700 MHz) specifically for rural coverage in Antigua. Many international phones omit these bands. Without them, you may lose connectivity in remote parts of the main island, especially if you are on Flow’s network.

No. eSIMs sold to travellers by international providers do not require local ID registration upon activation. Local prepaid SIMs from Flow or Digicel may ask for identification, but this eSIM bypasses that process.
