 Yes. Bolt and Uber are the most popular ways to get around Portugal, and reliable data is essential to book rides and avoid carrying cash. 

 Yes. Coverage is generally good in the towns along the Douro River like Pinhão, though signal may drop briefly on the train or boat between vineyards. 

 Yes. You will have strong signal in major towns like Lagos and Albufeira, allowing you to upload videos from the Benagil Cave boat tours instantly. 

 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. 

Yes, 100%. Buying a physical "prepaid" SIM at Lisbon Airport (from Vodafone, MEO, etc.) requires you to find the kiosk (which is often very crowded), wait in a long line, and go through a mandatory passport registration process as required by EU law. Our eSIM is 100% digital, requires no ID registration, and can be installed before you fly, so you are connected the moment you land. 

 To give you the best speed and coverage, our eSIM connects to Portugal’s premium Tier-1 networks, typically Vodafone Portugal, MEO, or NOS. This ensures you get the fastest available 4G/LTE (and 5G) speeds, whether you are in Lisbon, Porto, or on the beaches of the Algarve.

• If you are from the UK (Post-Brexit): Most UK carriers (like O2, Vodafone, Three) have reintroduced daily roaming fees (e.g., £2-£6 per day).
• If you are from the USA/Canada/Asia: Your home carrier will charge expensive international rates (e.g., $10-$14 per day).

A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper than these roaming charges.
