RoameSIM eSIM Data Plans for Antigua and Barbuda

RoameSIM does not provide a genuine unlimited high‑speed data option for Antigua and Barbuda. The only plan that uses “Unlimited” in its title allocates 3GB of high‑speed data per day for a seven‑day period; after the 3GB limit the speed is reduced to 1000kbps.

Travelers can instead choose from fixed‑data plans. For example, a 10GB plan valid for 30 days is priced at $68.60, and a 20GB plan valid for 30 days is priced at $92.40. These plans support tethering and, where available, use 5G networks. Fixed data plans are generally more cost‑effective unless a user requires high‑volume unlimited usage.

RoameSIM offers an eSIM for Antigua and Barbuda that includes a phone number and SMS. Plans run from 1 GB to 20 GB of data, with validity periods from 7 days to 365 days and prices between $21.00 USD and $124.60 USD. The included phone number uses the +1 dialing code, which is a local number for Antigua and Barbuda.

Calls can be received and made on the plan, and SMS messages can both be sent and received. Users are advised to confirm current plan specifics directly with RoameSIM before purchasing.
