ZenSim does not provide a truly unlimited data eSIM for Pakistan. The plans labeled “Pakistan Unlimited” actually offer a maximum of 3 GB per day; after that limit the speed would be reduced, which is not indicated in the plan details.
ZenSim’s alternatives are fixed‑data eSIMs. For example, a 20 GB plan is available for both 10‑day and 30‑day validity, as is a 10 GB plan and a 5 GB plan, each with similar prices and tethering permissions. Choosing one of these fixed data plans can be more cost‑effective unless the user requires constant high‑speed access beyond the daily cap.
