nextSIM eSIM Data Plans for Antigua and Barbuda

nextSIM offers eSIM plans for Antigua and Barbuda that are labeled “Unlimited.” Each of these plans, however, contains a fixed data allowance—ranging from 1 GB to 2 GB per day or per total validity period—and after that limit is reached the speed is throttled to either 512 kbps or 2000 kbps. Because of this post‑cap speed reduction, the plans are not truly unlimited high‑speed data.

If a traveler prefers a consistent data experience, nextSIM also provides fixed‑data eSIM options for Antigua and Barbuda. For example, the 20GB 30‑day standard plan costs $89.86 USD, while the 50GB 30‑day premium plan is available for $1 271.18 USD. These fixed plans offer higher data allowances without the speed reduction that follows a capped “Unlimited” plan.

NextSIM does not provide an eSIM with a phone number or SMS capability for Antigua and Barbuda. Only data‑only plans are available from the provider for that destination. Travelers who need to make voice calls or send messages can rely on VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, though they should confirm that these apps are accessible in Antigua and Barbuda before purchasing.

nextSIM offers a total of 47 single‑country plans and 12 multi‑country plans that include Antigua and Barbuda. The available plans span a price range of $8.44 to $1, 254.09 and data caps between 1 GB and 50 GB. Plans are divided into fixed data amount offerings, where a set amount of data is available for the entire validity period, and daily data cap options, which limit usage on a day‑by‑day basis.
