ZenSim does not provide a truly unlimited data eSIM for India. The plans that include “Unlimited” in their name actually offer a fixed high‑speed allowance of 3 GB per day with a reduced speed of 1000 kbps after the quota is reached. All other India‑specific plans have a hard cap, such as the India 40GB plans that provide 40 GB for 15 or 30 days.
For travelers looking for a high‑capacity option, ZenSim offers fixed data plans like the India 40GB — 30 days plan, which delivers 40 GB over a 30‑day validity period. These fixed plans can be more cost‑effective for moderate data usage compared to plans with a daily cap that slows speed after the limit.
