HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric on the composite, with App 5.0, Support 5.0, an iOS and Android app, and unlimited plans from $5.

Airalo, Saily, and Nomad rate cards ($4.50, $3.99, and $3.00 per GB) are not Portugal checkout prices.
Dimension scores, 0-5 on our rubric

Airalo's $4.50/GB figure is a rate card. HelloRoam's Portugal checkout starts at $2.21 for 1GB, so the coverage-breadth lead is not a lower Portugal price.
Dimension scores, 0-5 on our rubric
