nextSIM does not offer any plans that provide unlimited use of high‑speed data for Puerto Rico. Every plan on the provider’s catalog lists a specific data cap, whether it is 1 GB, 2 GB, or a larger, fixed allowance.  
Travelers can instead choose from one‑of the fixed‑data options. For example, the 100 GB 30 days plan is available for $118.03 USD, and the 20 GB 30 days plan is offered for $46.92 USD. These plans give a larger amount of high‑speed data in exchange for a straightforward price and may be more economical for those who need more data than the lower‑capacity daily or weekly packages, which reduce speed after the limit is reached.
