nextSIM does not provide a truly unlimited high‑speed data plan for the Dominican Republic. The packages that carry “Unlimited” in the name actually offer 1 GB per day or 2 GB per day and, once the allotted data is used, the speed throttles to 512 kbps or 2000 kbps. Because of that limitation, these plans are not unlimited in the sense of unlimited high‑speed usage without a data cap.
Users looking for a flatter data experience may consider one of the fixed‑data plans. For example, a 10 GB 30‑day plan costs $88.94 USD, while a 50 GB 30‑day plan costs $1,287.28 USD. These examples illustrate the range of available fixed‑data options but are not an exhaustive list of all plans that nextSIM currently sells for the Dominican Republic.
