An eSIM is a SIM card built into your phone. You buy a data plan online, scan a QR code, and your phone gets mobile data in Portugal without a physical card. It only works on phones that support eSIM and are not locked to one carrier. Both brands below have a compatibility list on their Portugal page. Check it first.

This page compares two brands on facts printed on their own Portugal pages. We have not tested either one. The order is alphabetical.

What each Portugal page says

Airalo Yesim
Portugal-only plans Yes, “Fixed data” and “Unlimited” Yes, “Fixed plans” and “Unlimited plans”
Unlimited plan lengths shown 3, 5, 7, 10, 15 and 30 days From 1 day, longer plans cost less per day
Network named on the page NOS, plus 2 others Not named in the text we read
Regional plans EU and UK, Europe, Global Europe and UK (33 countries), Global (83 countries)
Plan type Not stated in the text we read Data only
Hotspot sharing Not stated in the text we read “Depends on operator”
Activation window Not stated in the text we read Within 180 days of purchase
Refund Not stated in the text we read Yesim says 100% refund guarantee, as per its refund policy

Read the table as “what the page prints”. An empty cell does not mean the feature is missing. It means the page text we read did not say.

What we cannot tell you yet

  • Which is cheaper in Portugal. Prices are not printed here. Both change often. Open each page and compare the same number of days.
  • Which has better signal. That needs a test on the ground. We have not made one.
  • Whether you need a Portugal-only plan. If your trip also visits Spain or France, a regional plan may fit better. Both brands list one.

Before you buy

  1. Check that your phone supports eSIM and is unlocked.
  2. Install the eSIM at home on Wi-Fi if the brand allows it. Yesim says you can activate it later. Check the activation rule for your plan.
  3. Compare the same number of days on both pages.

How we made this page

We read each brand's own Portugal page in a browser on 2026-10-01 and copied only plain facts. Prices are left out on purpose: plan prices change and show in a currency we could not read cleanly. Review text and star ratings on those pages are the brands' own claims, so they are not used. We have not tested either eSIM.

Research and first drafts are AI-assisted. Every figure comes from open data listed on the page with its source and date, and a person reviews each page before it goes live.
