ETravelSim does not provide a truly unlimited data eSIM for North America. Their plans that use the term “Unlimited” actually cap the high‑speed data at 100 GB for the validity period. Once that amount is reached, the connection speed is reduced, although the exact throttled speed is not specified.
For travelers who need large data allowances, fixed‑data options are available. For example, a 50 GB plan is offered for 30 days at $64.99 USD, and a 50 GB plan with a 365‑day validity is available for $109.99 USD. Choosing a fixed‑data plan can be more cost‑effective for moderate usage and provides a clear limit that helps travelers avoid surprise throttling.
