ETravelSim does not provide a truly unlimited data eSIM for the United States of America. Every plan that carries the word “Unlimited” in its name actually has a data cap, such as 4GB per day or a total of 100GB for a given validity period. When a capped plan reaches its limit, the speed is throttled to 128kbps for the daily‑capped options, while the 100GB plans simply stop providing high‑speed data after the allotted capacity is exhausted.
If unlimited high‑speed data is required, a fixed‑data alternative is available. For example, a 100GB plan is available for 7, 15, or 30 days, and other large‑data plans such as 30GB, 50GB, or 60GB for 30 days can also be selected. These fixed‑data plans can be more cost effective for travelers who need substantial usage but are not extreme data consumers.
