eSIMCard does not provide a truly unlimited data eSIM for Puerto Rico. All of the plans that carry the word “Unlimited” in the name actually supply a fixed data allowance—such as 1GB per day or 2GB per day—with a reduced speed of 500kbps or 2000kbps after the high‑speed limit is reached. Therefore, the high‑speed data is not unlimited.
If a traveler needs more data without the throttling, eSIMCard offers fixed data plans. For example, the 50GB eSIM Data For 30 Days in Puerto Rico gives 50GB of unthrottled data for 30 days, and the global 100GB plan spans 180 days and covers Puerto Rico among many other countries. Choosing one of these fixed data plans can be more cost‑effective for heavy data users and eliminates the post‑cap speed reduction.
