Qrispy eSIM does not provide a true unlimited data eSIM for United States of America. All plans for the United States are pay‑as‑go data credit, meaning the amount listed (for example 10GB, 5GB, 3GB, 2GB, or 1GB) represents roughly the amount of data the purchased credit buys at the destination’s rate, not a fixed allowance that must be used within a set validity period. The data credit does not expire, so unused data can be carried over to future trips. Travelers who need more data can top up their balance as needed, and the price per gigabyte generally decreases with larger upfront credits.
