Before booking
Reference option: unlimited data for 3 days, US$11, observed in the supplier’s USD catalogue. This is not a euro quote or the cheapest plan in the whole catalogue. Confirm your phone is unlocked and eSIM-compatible. Check activation, fair-use rules, tethering, coverage, voice/SMS and refund conditions for your chosen plan before buying. If your existing tariff includes Spanish roaming, another eSIM may be unnecessary.
