Supera link does not provide an unlimited data eSIM plan for Spain. All of its available plans for the country are fixed‑data packages, such as 30GB for 30 days at $22.04 USD, 20GB for 30 days at $16.78 USD, 15GB for 30 days at $13.49 USD, 10GB for 30 days at $11.07 USD, and a 5GB per day plan for $3.59 USD. These plans come with 3G, 4G, and 5G coverage in Spain, with tethering allowed on most options and a reduced speed on the 5GB/day plan.
Because Supera link offers only fixed data plans in Spain, choosing one of the higher‑allowance packages can be more cost‑effective for travelers who need a large amount of data. Unlimited plans are not available through Supera link for Spain.
