What to check before buying a travel eSIM
- eSIM hardware: dial *#06# , if an EID number appears, you're compatible.
- Carrier unlock status: phones bought on instalment plans may be locked to your home carrier. Most outright purchases are unlocked.
- iOS version: iOS 12.1 or newer for full eSIM support.
- Android version: Android 9 or newer typically supports eSIM, though it depends on the manufacturer.
- Region-specific variants: some Samsung models sold in Hong Kong or China are dual physical SIM with no eSIM , verify your specific model number.

Tip: if your current phone doesn't support eSIM but you travel often, an unlocked, mid-range eSIM-capable phone (e.g., Pixel 7a, iPhone SE 3, Samsung Galaxy A55) makes an excellent secondary travel device , pair it with a Cellesim plan and you have a full mobile internet kit for any destination.
Yes! This is the most important question for island travelers. Our eSIM plan covers all of Portugal, including the autonomous regions of the Azores and Madeira islands. You can use the same plan to explore Lisbon and then fly to São Miguel (Azores) or Funchal (Madeira) and stay connected.
It depends. Portugal is in the EU, so "Roam Like at Home" applies only to EU citizens.
- 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.
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.
Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.
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.
Yes. Portugal is a top hub for digital nomads, and our eSIM provides stable 4G+/5G speeds suitable for Zoom calls from cafes in Lisbon or Ericeira.
