Cheapest eSIM for Portugal: the numbers
As of 31 August 2026, 15:21 GMT, the cheapest eSIM for Portugal is eSIMCard with 100 GB for 31 Days at $35.41. That is $0.35 per GB, the best rate of the 168 plans we compare from 9 providers. 95 plans include 5G. 53 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which mobile networks does Portugal have?
Regulator ANACOM reports 5G in all 308 Portuguese municipalities and 75.7% of parishes, and 4G reaches over 99% of the population.
- MEO: MEO is the Altice owned incumbent and had the fastest 5G build in the year to Q1 2026, growing its 5G station count 33.5%, with sites in 307 of Portugal's 308 municipalities.
- NOS: NOS has 5G stations in all 308 municipalities and the highest share of its sites carrying 5G, at 94% as of late 2025.
- Vodafone: Vodafone leads Portugal on 5G scale with 5,536 base stations as of Q1 2026, the most of any operator, and covers every municipality.
- Digi: Digi arrived as the budget disruptor and already runs 2,695 5G stations reaching 306 municipalities, forcing the big three to compete on price.
MVNOs matter little in Portugal. The price pressure comes from Digi, whose entry pushed MEO, NOS and Vodafone to sharpen their prepaid offers.

Is 5G available in Portugal?
All four operators run 5G nationwide at municipality level. Vodafone has the most 5G stations, NOS has 5G on almost all of its sites, and cities plus the Algarve are well served.
How much data do you need in Portugal?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Portugal right now:
Are unlimited eSIMs for Portugal really unlimited?
Not always. 31 of the plans above are sold as unlimited. Most unlimited travel plans have a fair use rule. You get full speed for a daily amount, often 1 to 5 GB, then the speed drops to around 1 Mbps until the next day. That is fine for messages and maps but slow for video. If you know how much data you use, a fixed plan with a low price per GB is usually the better deal. That is why we rank by price per GB and not by labels.
eSIM or a local SIM at the airport in Portugal?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Portugal starts at $35.41 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Portugal eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in Portugal
EU visitors can roam at home rates. Bring your passport if you want to register a local prepaid SIM.
Vodafone has a store in Lisbon Airport Terminal 1 selling tourist plans from about 20 to 35 euros, such as 20 GB with 500 minutes for 20 euros. City stores are cheaper, with Vodafone Ready data plans at 10 euros for 55 GB.
Skip the airport counter and buy a data heavy prepaid plan in town for half the price. Lycamobile and Digi offer the cheapest data if you shop around in Lisbon or Porto.

Which networks will my eSIM connect to in Portugal?

Do Portugal eSIMs support 5G?
95 of the 168 plans we track for Portugal include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I top up my Portugal eSIM if I run out?
Yes. 53 of the 168 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
How many GB do I need for a week in Portugal?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is MegaEsim at $2.87.
