Best eSIM for Portugal (2026), Ranked

Best value. Local carrier, local pricing.

MEO is the largest mobile network in Portugal. Their eSIM Enjoy is a tourist product: buy online, get QR code by email (usually within an hour), install, go. It supports 5G and comes with validity options of 15, 20, or 35 days.

Starting at €10. That’s local pricing, not the markup you pay through travel eSIM apps. MEO also has the widest coverage in Portugal, including rural Alentejo, Madeira, and the Azores.

The tradeoff: the purchase flow is a Portuguese carrier website, not a slick travel app. It’s not hard, but it’s not as polished as Airalo or Saily.

• Pros: Cheapest per-GB, largest Portuguese network, 5G support, long validity options
• Cons: Less polished buying experience than travel apps, Portugal-only

Easiest setup. The default travel eSIM.

Airalo is the biggest eSIM marketplace and the most polished app-based experience. Portugal plans start at US$4 for 1 GB / 7 days. Buy in the app, scan QR, install. First-time eSIM users will have the least friction here.

Uses Vodafone PT network, which is excellent in cities and along the coast.

Plan	Price	Validity
1 GB	US$4.00	7 days
3 GB	US$8.00	30 days
5 GB	US$12.00	30 days
10 GB	US$18.00	30 days

• Pros: Smoothest app experience, reliable Vodafone network, wide plan selection
• Cons: More expensive per-GB than MEO, data-only

Cheapest travel eSIM app. Slightly beats Airalo on price.

Saily is the budget pick among travel eSIM apps. Portugal plans from US$3.99 for 1 GB / 7 days, up to 20 GB / 30 days. Auto-activates when you land.

Made by the same company behind NordVPN. Clean app, transparent pricing, no surprises. Slightly cheaper than Airalo for the same type of product.

Plan	Price	Validity
1 GB	US$3.99	7 days
3 GB	US$9.99	30 days
5 GB	US$13.99	30 days
10 GB	US$22.99	30 days
20 GB	US$36.99	30 days

• Pros: Cheapest travel eSIM app, clean interface, auto-activation
• Cons: Data-only, no unlimited option

Unlimited data. No caps, no math.

Holafly gives you unlimited data on Vodafone PT. No data caps, no top-ups, no worrying about usage. The price is higher than capped plans, but the convenience is real.

Plan	Price	Data
3 days	US$11.70	Unlimited
5 days	US$16.90	Unlimited
7 days	US$22.10	Unlimited
15 days	US$40.30	Unlimited
30 days	US$74.90	Unlimited

Worth it if you’re working remotely from Lisbon, creating content, or just hate monitoring data. Overkill for a weekend in Porto where you only need maps and messaging.

• Pros: Truly unlimited, Vodafone network, zero management
• Cons: Expensive for light users, data-only, hotspot sharing limited

The only real option for Portugal + Europe in one product.

Vodafone’s travel eSIM gives you unlimited data in Portugal plus a big chunk of data across the EEA and UK. This is the pick if your trip includes Spain, France, or anywhere else in Europe.

Plan	Portugal	EEA + UK	Validity
Standard	Unlimited	25 GB	15 days
Plus	Unlimited	45 GB	30 days
Premium	Unlimited	75 GB	30 days

They also have a Portugal-only plan: 10 GB for 7 days, no calls/SMS. Less interesting unless the Europe bundle doesn’t fit your trip.

• Pros: Unlimited Portugal data + generous EU roaming, official carrier product
• Cons: More complex pricing, less convenient than app-based options

Solid mid-range. Good if you want flexibility.

Nomad uses MEO’s network and starts around US$8 for 5 GB / 30 days. Their add-on system lets you buy more data without replacing the eSIM.

Fine, but not the best at anything for Portugal specifically. MEO is cheaper for local carrier pricing, Airalo/Saily are more polished apps, and Holafly is better for unlimited.

• Pros: Flexible add-ons, MEO network, long validity
• Cons: Not the cheapest, not the best app, not the best at anything specific

Another local option. Less tourist-friendly.

NOS is Portugal’s third major carrier. They sell prepaid eSIMs online with unlimited data and 5G for 15 days. A solid product, but the website is primarily in Portuguese and the purchase flow is less streamlined for tourists than MEO’s.

If MEO’s eSIM is sold out or you want an alternative local carrier, NOS works. Otherwise, just get MEO.

• Pros: Local carrier pricing, unlimited data, 5G
• Cons: Portuguese-language website, less tourist-oriented
