eSIM for Porto
Signal is good in the city and thinner up the valley. Porto is small and climbs a hill over the Douro river, with port cellars on the far bank and vineyards stretching inland.

Porto: what to know before you go
- Airport to centre
- Metro line E runs from Francisco Sá Carneiro (OPO) to the centre in about 30 minutes. Ride apps are an option too.
- Booked sights
- Popular places like the Livraria Lello bookshop sell tickets you show on the phone. In busy months, book in advance.
- Across the river
- You find the port cellars in Vila Nova de Gaia, on the other bank. Tours are booked online, and a map gets you to the right door.
- Up the Douro
- Whether by train, boat or car, a day up the valley goes through narrow gorges where the signal fades. Save maps for the drive.

Questions about Porto
- Is there signal in the Douro valley?
- Yes in the towns, though it can cut out along the river. Save an offline map of the valley, above all if you are driving.
- What is the cheapest Porto eSIM plan?
- Porto uses the Portugal plans, because an eSIM belongs to a country and not to a city. $3.49 gets you 3 GB for 30 days. Data sizes range from 3 GB to 50 GB across 9 plans, and there are unlimited day passes too.
- Which mobile networks does the Porto eSIM connect to?
- You get NOS and Vodafone, on 5G wherever it is available. The operators are listed on every plan, so you can check before you buy.
- Is there an unlimited data plan for Portugal?
- Yes, the day passes. Each day starts with a full speed allowance, and after it you stay online at a reduced speed of 500 Kbps.
- Will my phone number still work?
- Yes. Every plan is data only, so your regular line stays active for calls and texts, and WhatsApp carries on as usual.
- Should I buy a local SIM card in Porto?
- There is no need. An eSIM is a digital SIM card that you install from a QR code before the trip, so you skip the airport kiosk and never open the SIM tray.
- How does it compare with roaming in Porto?
- For an EU SIM, roaming here is billed like at home, up to the data your plan allows abroad. The eSIM is useful once that allowance is gone, or if your line comes from outside the EU, where carriers usually charge by the day or by the megabyte.
- When is the best time to install the eSIM?
- At home, on Wi-Fi, before you leave. Once you arrive, pick the Fizztrip line for mobile data and switch data roaming on for that line.
- When does the plan start counting days?
- At the first connection at your destination. Buying the eSIM or installing it does not start the clock, so a 30 day plan runs for 30 days from the moment it first joins a network there.
- Can I buy the eSIM weeks before my trip?
- Yes. Validity only starts at the first connection at your destination, so buying or installing early does not use up any days. Install it before the "Install by" date on your order.
- Is there a deadline to install the eSIM?
- Yes. Your order and the site show an "Install by" date, and an eSIM that is still not installed after that date expires. Buying early is fine: just install it on Wi-Fi before then.
- What happens when my data runs out?
- The connection pauses and nothing extra is charged, since every plan is prepaid. Top up from the eSIM page and you are back online on the same eSIM, with nothing to reinstall. On a day pass you get a full speed allowance each day. Once it is used, you stay connected at a lower speed (500 Kbps) until the next day begins.
- Can I add data later?
- Yes, straight from the eSIM page. The extra data goes onto the eSIM you already have, so there is nothing new to install.
- Can I share data with a hotspot?
- Yes. Hotspot traffic uses the same plan data and Fizztrip adds no fee for it. Keep in mind that a laptop burns through data much faster than a phone, so for remote work a day pass or a larger plan is the safer pick.
