Phone & SIM Cards in Portugal — Mobile Plans Guide

Mobile Operators in Portugal

Portugal has four main mobile network operators:

• MEO (by Altice Portugal) — The largest operator with the widest coverage, including rural areas. Offers prepaid and postpaid plans, as well as bundled packages with home internet and TV.
• NOS — Strong network coverage in urban areas. Also a major cable TV and internet provider. Offers competitive mobile plans and bundles.
• Vodafone Portugal — Known for good network quality and competitive data plans, especially in cities. Popular with younger users and tech-savvy consumers.
• NOWO (MásMóvil group) — A smaller, budget-friendly operator with growing coverage. Good for basic plans at lower prices.

All four operators offer 4G coverage across most of the country and 5G in major urban areas. Coverage can be weaker in remote rural areas — check coverage maps on each operator’s website for your specific location.

Prepaid SIM Cards (Pré-Pago)

A prepaid SIM card is the quickest way to get a Portuguese phone number. You buy the SIM, load credit, and use it without any contract commitment.

Advantages of Prepaid

• No contract or commitment period
• No credit check required
• Easy to buy — available on the day you arrive
• Good for controlling spending — you only use what you load

Disadvantages of Prepaid

• Higher per-unit costs compared to postpaid plans
• Less data included for the price
• Credit expires if not used or topped up within a certain period
• Some services (e.g., certain app subscriptions) prefer a postpaid number

Postpaid Plans (Pós-Pago)

A postpaid plan (contrato) gives you a monthly allowance of calls, texts, and data. You receive a bill each month. Postpaid plans typically offer better value for heavy users.

To sign up for a postpaid plan, you generally need:

• NIF (Portuguese tax number)
• Valid ID (passport, residence permit, or EU ID card)
• Portuguese bank account (IBAN) for direct debit
• Proof of address (some operators require this)

Contracts are usually for 24 months, though some operators offer 12-month or no-commitment options at a slightly higher monthly price. Read the contract carefully before signing, especially regarding early termination fees (fidelização).

Where to Buy a SIM Card

You can buy a prepaid SIM card at:

• Operator stores — MEO, NOS, Vodafone, and NOWO all have retail stores in shopping centres and high streets across Portugal. Staff can help you choose a plan and activate the SIM.
• Supermarkets — Large supermarkets (Continente, Pingo Doce, Auchan) sell prepaid SIM cards near the checkout or at the electronics counter.
• Electronics stores — Worten, FNAC, and similar retailers stock SIM cards from all operators.
• Airport kiosks — Some operators have kiosks or vending machines at Lisbon, Porto, and Faro airports, though selection may be limited.
• Online — Operators sell SIM cards online with home delivery. This usually requires a Portuguese address.

Activating Your SIM

After purchasing a prepaid SIM, you need to activate it. Portuguese law requires identity verification for all SIM cards. The activation process typically involves:

1. Insert the SIM into your phone
2. Call the operator’s activation line or use their app
3. Provide your ID details and NIF
4. Wait for activation confirmation (usually within minutes to a few hours)

If you buy the SIM in an operator store, the staff will typically handle activation on the spot.

Top-Up Methods

Topping up a prepaid SIM in Portugal is easy and can be done several ways:

• Multibanco (ATM) — Use any Multibanco ATM to top up your phone. Select “Carregamento de Telemóvel” and enter your number and amount.
• MB WAY — Top up through the MB WAY app from your linked bank account.
• Operator app or website — Top up with a debit or credit card through the operator’s app or website.
• Physical vouchers — Buy top-up vouchers at supermarkets, newsagents (tabacarias), or CTT post offices. Scratch to reveal the code and enter it via the operator’s short code.
• Payshop — Top up at Payshop agents (found in many small shops).

Choosing the Right Plan

When comparing mobile plans in Portugal, consider these factors:

• Data allowance — How much mobile data do you need? If you use streaming, video calls, or navigation heavily, prioritise data.
• Calls and texts — Most plans include unlimited or generous domestic calls and texts. Check if international calls are included or available as an add-on.
• Coverage — Check the operator’s coverage map for your home, workplace, and regular routes. MEO generally has the widest rural coverage.
• Contract length — Shorter contracts or prepaid give flexibility; longer contracts give better monthly rates.
• Bundling — If you also need home internet and TV, bundling everything with one provider can save money. See our Utilities Guide for more on internet bundles.
• International calls — If you call family abroad regularly, check whether international minutes are included or look for add-on packages.

eSIM Availability

Major Portuguese operators including MEO, NOS, and Vodafone offer eSIM support for compatible smartphones, tablets, and smartwatches. An eSIM is a digital SIM embedded in your device — no physical card needed.

You can activate an eSIM online or in an operator store. This is convenient if your phone supports dual SIM (one physical + one eSIM), allowing you to keep your home country number alongside a Portuguese number. Check with your chosen operator for eSIM availability on your specific device and plan.

EU Roaming Rules

Under EU “Roam Like at Home” regulations, you can use your Portuguese mobile plan in other EU and EEA countries at no extra charge. This means:

• Make and receive calls at your domestic rate
• Send texts at your domestic rate
• Use mobile data at your domestic rate, subject to a fair-use policy

The fair-use policy means operators can set a data roaming limit (usually generous for postpaid plans, more restricted for prepaid). If you exceed this limit, a small surcharge may apply. Your operator must notify you before any charges kick in.

Keeping Your Number (Portabilidade)

If you already have a Portuguese mobile number and want to switch to a different operator, you have the legal right to keep your number. This process is called portabilidade (number portability).

To transfer your number:

1. Sign up with the new operator and request portability
2. Provide your current number and operator details
3. The new operator handles the transfer process
4. The transfer typically completes within one business day

During the transfer, there is usually only a brief interruption of service (minutes to a few hours). Your old SIM will stop working once the transfer is complete. Number portability is free of charge.

Wi-Fi Calling

Wi-Fi calling allows you to make and receive calls and texts over a Wi-Fi network when mobile signal is weak. This is useful in buildings with thick walls or in areas with poor mobile coverage. Most modern smartphones support Wi-Fi calling, and Portuguese operators have been rolling out support for this feature. Check with your operator and in your phone’s settings to see if Wi-Fi calling is available on your plan and device.

Common Questions

What documents do I need to buy a SIM card in Portugal?

To buy a prepaid SIM card in Portugal, you need a valid identification document (passport, residence permit, or EU ID card) and your NIF (Portuguese tax number). Portuguese law requires SIM card registration with valid ID, so anonymous SIM purchases are not possible.

Can I use my Portuguese SIM card in other EU countries?

Yes. Under EU roaming regulations (“Roam Like at Home”), you can use your Portuguese mobile plan in other EU/EEA countries at no extra charge for calls, texts, and data, subject to fair-use limits. This applies to both prepaid and postpaid plans. Check your operator’s fair-use policy for data limits while roaming.

What is the difference between prepaid and postpaid plans in Portugal?

Prepaid (pré-pago) means you top up credit in advance and use it until it runs out. No contract or credit check is needed. Postpaid (pós-pago) means you sign a contract (usually 24 months) and receive a monthly bill. Postpaid plans typically offer more data and better value but require a NIF, Portuguese bank account, and sometimes a credit check.

Can I keep my phone number when switching operators?

Yes. Number portability (portabilidade) is a legal right in Portugal. You can transfer your existing Portuguese mobile number to a new operator. The new operator handles the process — just request portability when signing up. The transfer typically completes within one business day.

Do Portuguese operators offer eSIM?

Yes. Major Portuguese operators including MEO, NOS, and Vodafone offer eSIM support for compatible devices. You can activate an eSIM online or in-store. Check with your chosen operator for eSIM availability on your specific plan and device.
