Antigua and Barbuda: Mobile Coverage & Carriers
ESIMBYCOUNTRY at checkout · See all codes →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.
