Some local carriers issue eSIMs

Mobile services in Antigua and Barbuda are provided by two main operators: Flow and Digicel. Both carriers offer 3G and 4G/LTE networks commercially. The primary LTE bands available for roaming devices are Band 2 (1900 MHz) and Band 4 (AWS), which roaming eSIMs are likely to access when connecting to local networks.

Regarding eSIM availability, some local carriers in Antigua and Barbuda issue eSIMs, though information on this remains limited. No 5G networks have been commercially launched in the country at this time. Given the low confidence level in available data, travelers and users should verify current network capabilities and eSIM support directly with their service providers before arrival.

Compiled from public-record telecom facts (the MNO roster, commercially-launched 3G/4G/5G generations, deployed travel-relevant bands and local-eSIM support) and verified June 2026; see the source we compile this country from. This country's connectivity row is currently low-confidence (small / island / single-operator / fast-changing market), so treat the carrier, band and 5G details as a starting point we are still verifying. How we compile this. Plan prices are supplied by the eSIM provider feed at publish time, not stored here.
