eSIMCard’s plans that are labeled “Unlimited” for Spain actually contain a fixed data allowance. Each of these plans offers 1GB/day or 2GB/day of high‑speed data, and once the limit is reached the speed is throttled (for example to 512 kbps or 2000 kbps). Because a limit exists, these plans are not truly unlimited.
Travelers who need a higher, uninterrupted data volume can choose from the provider’s fixed‑data options. For instance, a 50 GB plan for 30 days is available at $31.39 USD, and there are additional 35 GB and 100 GB plans with longer validity periods. These fixed plans provide larger data pools without the speed reductions that accompany the “Unlimited” branded packages.
