nextSIM does not provide a truly unlimited data eSIM for North America. The plans that carry "Unlimited" in their name actually include fixed data allowances—1 GB per day or 2 GB per day—after which the speed is reduced to 512 kbps or 2 Mbps, respectively. Because of this throttling, the data is not unlimited in the sense of continuous high‑speed access.
Travelers who need more data can choose from nextSIM’s fixed‑data plans. For example, the North America 20GB 30Days Economy plan offers 20 GB for $45.47 USD, and the eSIM GLOBAL 30GB 30Days Premium plan delivers 30 GB for $779.72 USD. These higher‑cap options tend to be more cost‑effective unless the user is an exceptionally heavy data consumer.
