ByteSIM does not provide a truly unlimited data eSIM for Jamaica.
All ByteSIM plans for Jamaica have a specified data cap; for example the plans named “Jamaica Unlimited Data…” offer only 1 GB (or 1 GB per day) of high‑speed data and drop to a reduced speed of 10 000 kbps once that amount is reached.
Instead ByteSIM offers fixed‑data plans. Two examples with higher data for reference are the Jamaica 10 GB for 14 days plan priced at $45.90 USD for 14 days, and the Jamaica 10 GB for 3 days plan priced at $47.90 USD for 3 days. These plans provide a higher data allowance and not mandatory throttling until the limit is exceeded.
