GLOBAL YO does not provide an unlimited data eSIM for Portugal. The highest data allowance available is a 200GB plan valid for 60 days, priced at $99.99 USD, and there is also a 100GB plan for 60 days costing $59.99 USD.
If you need a fixed data plan instead, these options are usually more cost‑effective, especially for travelers who do not require extreme data usage. For example, the 200GB 60‑day plan offers a large buffer for browsing, streaming, and tethering, while the 100GB 60‑day plan is a more economical choice for moderate usage. These only represent a subset of the plans offered; additional fixed‑data options are also available.
