eSimFlare does not provide an unlimited data eSIM for the United States. All of its United States plans have a fixed data allowance. For example, the United States 50GB 180Days plan offers 50GB of data for 180 days at $56.20 USD, while the United States 20GB 90Days plan supplies 20GB of data for 90 days at $18.40 USD. These fixed‑data options are available in other U.S. plans with similar data caps and validity periods.
Because the data cap is capped, a fixed‑data plan can be a more cost‑effective approach for most travelers. It may be a better value than a theoretical unlimited plan unless the user requires extremely heavy data usage, in which case a higher‑cap fixed plan such as the 50GB option may be more suitable.
