Qrispy eSIM does not provide an unlimited data eSIM for Spain. The only available options are pay‑as‑you‑go data credits, ranging from 1 GB to 10 GB. Each credit can be purchased at the listed price, can be topped up at any time, and the balance does not expire, so any unused data remains available for later trips. If a traveler needs a large amount of data, buying the highest available credit (10 GB) gives the lowest effective cost per GB, and additional data can be added as needed.
