NOS is a strong starting point for unlimited data during a Portugal-only holiday. Vodafone Travellers is more useful if you want ordinary calls and texts as well as mobile internet. Roafly suits visitors who prefer to arrange an eSIM before departure and use a fixed data allowance over 30 days.
The important distinction is the plan, not just the operator. Some inexpensive Portuguese cards are mobile broadband products with no roaming, and their advertised uses may focus on tablets or hotspots. If you are still choosing between roaming, a SIM and rented WiFi, compare the broader internet options in Portugal first.

NOS offers more domestic data for heavy use, while Vodafone Travellers adds voice service. The Roafly plans last longer than the 15-day starter cards, which matters if a two- or three-week itinerary would otherwise require a renewal.
If your phone supports eSIM and you prefer to arrive with your data plan arranged, choose your allowance from the Portugal eSIM plans.

Which Local SIM Should You Choose?
NOS for unlimited data within Portugal
NOS Net Móvel prepaid combines a low initial cost with unlimited domestic data. It can be used in a smartphone, tablet or hotspot, so it is a practical shortlist option for video calls, navigation and sharing a connection during a holiday.
The decisive restriction is no roaming. Keep it for a trip within Portugal; do not buy it expecting the same service to continue across the Spanish border. Unlimited data also does not promise a particular speed: signal, congestion and network management still affect performance. The NOS prepaid terms cover the current starter card and top-up options.
Vodafone Travellers for calls and texts
Vodafone Travellers includes 25 GB and lasts 30 days from first use. Its voice and messaging allowances are:
-
500 shared minutes/SMS for national use.
-
50 shared minutes/SMS for included international destinations.
These are combined allowances, not 500 minutes plus another 500 texts. International calling is also destination-specific, so establish whether the country you want to call is included. The Vodafone Travellers plan details explain the package.
This is the more relevant option if you expect to call restaurants, accommodation or other ordinary telephone numbers. Its current upfront purchase price was not reliably published in the verified plan information, so get a complete quote before paying.
MEO Enjoy for mobile broadband
MEO Enjoy offers time-limited mobile internet with all data traffic included. Its positioning is mainly for computers, tablets and routers, making it more relevant to someone bringing a hotspot than to someone seeking a conventional phone plan.
The MEO Enjoy shop displayed the 15-day card at €10 when checked. Related promotional wording carried campaign dates that had already passed, so treat this as an displayed price to reconfirm, rather than an assured walk-in total.
Enjoy is for use in Portugal and does not include roaming. If you want to put it in a phone, establish that your intended device and use are supported before buying. Ask for a different MEO prepaid phone plan if regular calls and SMS are essential.
Where to Buy a SIM Card in Portugal
At the airport
Lisbon Airport has a Vodafone shop in Terminal 1’s public arrivals area, making a physical SIM purchase possible before you continue into the city. Airport buying is useful when you want staff to install the card and help you test it.
Allow time for baggage collection and any customs formalities in Portugal before the shop visit and your transfer. Late arrivals also need an alternative: a shop being at the airport does not mean it stays open around the clock.
Ask which exact plan is being sold and what the full starting cost includes. Do not assume that every airport counter stocks the same cards or matches an operator’s offer.
In town or delivered to your accommodation
Operator stores give you another opportunity to buy a card and discuss the right tariff. Taking the plan name from the comparison table makes the conversation easier than asking for “a SIM with internet.”
NOS also offers ordering with delivery to a hotel or apartment. Arrange this with your accommodation before ordering and leave enough time for delivery; it is less suitable when you need data immediately after landing.
Neither an airport location nor a city shop automatically establishes which purchase is cheaper. Compare the complete plan and initial payment, including any SIM, setup or required first top-up charges.
Documents, Payment and Activation
Bring your passport or another identity document in case the seller requests it. Requirements can vary by seller and ordering channel; carrying ID is preparation, not a claim that every tourist prepaid purchase has the same registration rule. delivery will also need usable recipient and address details.
Before paying, work through these practical points:
-
Device: Your phone must be unlocked and able to use the chosen physical SIM or eSIM.
-
Plan type: Request prepaid service without a long contract, with calls included if you need them.
-
Total payment: Ask for the complete initial amount and the payment methods accepted at that location.
-
Validity: Establish what starts the allowance period and when it expires.
-
Working connection: Turn WiFi off and test mobile data before leaving. Test an ordinary call too if voice service is part of your purchase.
Keep the receipt and any SIM PIN or PUK information. If your phone uses two SIMs, select the travel line for mobile data and review the home line’s roaming settings so it does not supply data unexpectedly.
Using Your SIM in Spain and Elsewhere in Europe
Crossing into Spain changes the buying decision. NOS Net Móvel prepaid and MEO Enjoy do not include roaming, even though they are sold by Portuguese operators.
Vodafone Travellers’ international call allowance is a separate feature from using mobile data abroad. Before choosing it for an journey, obtain the roaming countries, available data and any extra charges for that exact tariff. The domestic 25 GB allowance alone does not establish what you can use in Spain.
The same country check applies to an eSIM: a Portugal plan should not be assumed to cover another destination. Choose a package explicitly listing every country on your route if you want connection throughout the trip.
Before buying any extra SIM, look at your existing mobile plan. If it already includes enough roaming data in Portugal and your destinations, another purchase may add little value.
When a Roafly eSIM Makes More Sense
Roafly is useful when your priority is mobile internet over a 30-day trip and you would rather set up digitally than visit a shop. Its Portugal service uses Vodafone and NOS, and the purchased data allowance can also be shared through a hotspot. Top-ups are available if you need more data.
It is data, with no local phone number. Messaging and calling apps can use the connection, but it does not provide a normal Portuguese voice-and-SMS service. That trade-off matters if you need to telephone a business that does not use your preferred app.
Local unlimited data can be better value for frequent streaming or heavy laptop use. Roafly’s fixed allowances are more appealing when you can estimate your usage and value the longer validity and advance setup. To assess network and allowance differences in more detail, compare eSIM plans for Portugal.
Frequently Asked Questions
Can I buy a Portuguese operator eSIM instead of a physical card?
Yes. Vodafone offers eSIM options for visitors as well as physical SIM cards. Choose the specific digital tariff on its own terms; do not assume an eSIM has the same price, allowance or validity as a similarly named physical card. Your phone must support eSIM and be unlocked.
Can I extend a prepaid card for a longer stay?
Some prepaid cards can be topped up to add another period of service. NOS currently lists a €20 top-up for 35 days of unlimited domestic data. That is a renewal option for the card, distinct from the 15-day starter purchase. Establish when the new period begins before reloading.
Will a data-only SIM work for WhatsApp calls?
Yes, WhatsApp calls use an internet connection. The limitation is ordinary phone service: a data-only plan does not itself supply conventional mobile calls or SMS. Keep access to your home number if you need texts sent to it, and check any roaming charges with your home operator.
