Yes, ESIM.DOG offers unlimited data eSIM plans for Barbados. The provider lists several unlimited options with validity periods ranging from 1 day to 30 days and prices from $11.99 USD for a 1‑day plan up to $773.87 USD for a 30‑day plan. The plans are available on 5G networks and include a maximum speed of 512kbps for the Caribbean‑wide unlimited plan and 1000kbps for the FLOW Barbados unlimited plan, with a note that speeds may be throttled after heavy usage.
Because these are unlimited plans, the data allowance is not capped, but a Fair Usage Policy applies: after a certain amount of data is used, the speed may be reduced. Travelers who want to confirm the typical data volume that can be streamed at normal speed or who have concerns about speed restrictions should contact ESIM.DOG directly for the most current details.
