nextSIM does not offer a true unlimited‑data eSIM for Jamaica. All of its plans listed for Jamaica have a fixed data allowance and specify a reduced speed once that limit is reached. For example, the eSIM Unlimited Standard 1 Day Jamaica plan provides 1 GB of high‑speed data, after which the speed drops to 512kbps, and the eSIM Unlimited Plus 1 Day Jamaica plan offers 2 GB before speed throttling to 2000kbps.
Travelers who need a more generous data bundle can choose from a range of fixed‑data plans. A notable option is the eSIM Jamaica 20GB 30Days Economy plan, which provides 20 GB of data for 30 days at an affordable price. If a higher capacity is required, nextSIM also offers 30 GB, 40 GB, and 50 GB global plans that cover Jamaica along with 157 additional countries. These fixed‑data plans give users predictable speeds and faster rates than the “Unlimited” options that throttle after the initial cap.
