Network & Coverage

Stay connected across every corner of Portugal

Your eSIM connects to the local networks of Vodafone and NOS — for fast, reliable 4G/5G from the hills of Lisbon and the riverfront of Porto to the beaches of the Algarve and the islands of Madeira and the Azores.

Vodafone
Excellent high-speed coverage throughout Lisbon, Porto and major tourist hubs — ideal for streaming and video calls.
NOS
Strong, dependable speeds on your eSIM's local partner network.
Popular destinations covered
Lisbon Porto Algarve Faro Madeira Sintra Cascais Lagos Coimbra Azores

From riding Lisbon's tram 28 and exploring Porto's Ribeira to road-tripping the Algarve coast or hiking the levadas of Madeira, your unlimited data keeps maps, translation and ride-hailing apps running wherever Portugal takes you.

Will my Portugal eSIM work on the islands like Madeira and the Azores?+
Yes. Your eSIM runs on Portugal's leading carriers, which provide solid 4G/5G across Madeira and the main Azorean islands such as São Miguel, including Funchal, Ponta Delgada and most resort and coastal areas. Signal may dip briefly on remote mountain or hiking trails but reconnects automatically.
Can I share my Portugal eSIM as a hotspot?+
Yes — tethering is fully supported, so you can share your unlimited connection with a laptop, tablet or a travel companion's phone — perfect for working from a Lisbon café or keeping the group online during an Algarve road trip. One thing worth knowing: hotspot traffic counts towards the same 5 GB daily full-speed allowance, and tablets or laptops get through it faster than a phone. If you plan to keep several devices online all day, one of our data packages with a fixed GB volume is usually the better fit.

Frequently asked questions

Everything you need to know about your Portugal eSIM

Is the data truly unlimited? +
Yes — there is no data cap and your connection is never switched off. Like every unlimited travel eSIM, the plan carries a daily full-speed allowance: in Portugal that is 5 GB per day. Beyond it you stay online at a reduced speed (512 kbps) for the rest of that day, and full speed returns automatically the next day. Hotspot traffic counts towards the same allowance. We publish the exact figure for all 181 destinations — see our daily allowance by country.
When does my eSIM activate? +
Your eSIM activates the moment you first connect in Portugal. Your days don't start until you're there — so you can install it weeks before travel with no waste.
Which devices are compatible? +
Any unlocked eSIM-compatible device: iPhone XS and later, Google Pixel 3+, Samsung Galaxy S21+, and most modern Android flagships. Check Settings → Cellular → Add eSIM to confirm.
How do I install the eSIM? +
After purchase, check your email for the QR code. On your phone: Settings → Cellular (or Mobile Data) → Add eSIM → Scan QR Code. It takes under 2 minutes. Full step-by-step instructions are included in the email.
What if I need help? +
Our team is available 24/7 via live chat at aerosims.com — day or night, before or during your trip.
Could my internet speed ever change? +
Yes — once you pass the daily full-speed allowance, which in Portugal is 5 GB per day. After that, data keeps working at a reduced speed (512 kbps) for the rest of that day and returns to full speed the next day. Nothing is cut off, and hotspot traffic counts towards the same allowance. This tier is set by the local operator, not by AeroSims. Full details for every destination: daily allowance by country. If you prefer a guaranteed volume at full speed, our data packages give you a fixed number of GB.
Can I extend it if I stay longer? +
Often yes. While the eSIM is still active, open your personal eSIM page — the link is in your delivery email — and you will see there whether extra days can be added to your plan. If they can't, another eSIM for the same destination arrives by email and installs alongside the one you already have.
