Does this eSIM also work in Spain?

 This specific plan is valid only within Portugal (or, if it's a regional plan, you'd say "Yes"). This is a critical point. If you are on an "Iberian" tour and take a bus from the Algarve to Seville (Spain) or from Lisbon to Madrid, your connection will stop at the border. For this, we highly recommend our Europe Regional eSIM, which covers both Portugal and Spain.
