ZenSim does not provide a truly unlimited data eSIM for Panama. The only plan that carries “Unlimited” in its name, Panama Unlimited STANDARD – 5 Days, actually offers 3 GB per day and reduces speed to 1000 kbps once that daily limit is reached, so it is not an unlimited plan.
Instead, ZenSim offers fixed‑data plans that give a set amount of high‑speed data for a specified period. Examples include the Global 40 GB plan valid for 90 days and the Panama 20 GB plans valid for 15 or 30 days. These fixed data plans can be more cost‑effective for most travelers unless they need an extremely high data volume.
