Firsty eSIM Plans for Antigua and Barbuda

Firsty has not published which mobile operators it uses in Antigua and Barbuda, so the radio side is unknown rather than a sign of weak reach; the table above is where to check the available allowances and validity. Its large range of plans makes sizing the real decision, with the risk of buying more data than a fortnight needs. Firsty lists service up to 5G, and top-up is stated as available, so an exhausted plan can be extended rather than rebought. It does not say whether voice, SMS or a phone number is included.
