eSimfly does not offer a truly unlimited data eSIM for Puerto Rico; all of its plans there have a fixed data allowance. The plan titled “Caribbean Islands Unlimited 7 Days” actually provides 3 GB per day and, after that limit, the speed drops to 1000 kbps, so it is not an unlimited plan.
Travelers who need large amounts of high‑speed data can choose fixed‑size options such as the Global 100 GB 31 Days plan, which supplies 100 GB for a month, or the Puerto Rico 20 GB 30 Days plan. These fixed data plans can be a more cost‑effective choice unless a user requires an extremely high data volume that exceeds the plan limits.
