MTX Connect does not provide an unlimited data eSIM for Portugal. The available plans for Portugal are fixed‑data bundles, each offering 10GB of data that must be used within 30 days. Examples include the 10GB LOCAL plan, the Portugal 10GB plan, the 10 GB EU+ plan, the Portugal 10GB Unthrottled plan, and the 10 GB plan that covers Portugal and many other countries.
Choosing a fixed‑data plan can be more cost‑effective for most travelers, unless the user expects to consume data at a very high rate that would exceed the 10GB allowance.
