Spanish Phone Plans and Home Internet for Americans: SIMs and Rights

Your first step toward a Spanish phone plan is having your U.S. phone unlocked. Then buy a SIM card, which the shop hands over only after recording an identity document such as your passport. Home internet usually means fiber, whose networks reached 95.92 percent of Spanish households on June 30, 2025. From there, Spanish telecom law sets each step: a free contract summary before you sign, contracts of 24 months at most, a ported number live within one working day of the agreed date, and a complaint route through the operator, then a ministry office. This article is for informational purposes only and is not legal advice; verify current requirements with the relevant Spanish authority or a licensed professional.

What can go wrong when you set up a phone and internet in Spain?

Five snags can catch you at this stage.

• A locked U.S. phone. If your phone was not sold unlocked, it is probably locked to its carrier, eSIM included (FCC), and a Spanish SIM will not work in it.
• Roaming on a U.S. plan. Most U.S. plans leave out use abroad, the FCC warns, and the charges can turn up a billing cycle later.
• A costly exit. A permanencia, which is simply a minimum-stay clause, arrives with perks such as a free connection or a cheaper router, and your contract states what leaving early will cost (OAUT).
• A missed deadline. The Oficina de Atención al Usuario de Telecomunicaciones (OAUT), the ministry’s telecom user office, takes your case only if you first complained to the operator within one month (Orden ITC/1030/2007, article 4).
• An address without fiber. In villages, installation takes longer, according to the CNMC, the markets and competition regulator. And the universal service designation ends on December 31, 2026, per a ministry memo.

The rest of this guide takes each of them in turn.

Your rights and deadlines, step by step

Getting a Spanish number: your phone, the SIM and your ID

Get the phone unlocked. Your carrier may refuse until you pay the balance or meet the contract terms, says the FCC’s unlocking guide of January 14, 2025. Under a voluntary industry code, which is not an FCC rule, carriers act on requests within two business days, and a prepaid phone is unlocked on request one year after activation at the latest. Once your phone is unlocked, its eSIM can be reprogrammed in the settings for a new provider (FCC eSIM FAQ).

What the shop records. For your prepaid card, Ley 25/2007, the data retention law, requires a register holding your name, surnames, nationality and the number and type of your identity document, with no residence requirement. The AEPD, Spain’s data protection authority, read it in case E/03790/2015 as requiring you to show the document, with no copy required. Under article 4 of the immigration law and article 13 of the citizen security law, a foreigner’s identity document is the one their home country issues, which for you means the U.S. passport. No official page says outright that a passport alone is enough.

Contracts and eSIMs. In a January 2023 decision on a fraudulent eSIM duplicate, the AEPD read the law as covering every SIM, prepaid or contract. No official rule turned up on identification for eSIM activation or online sales, or on which document a postpaid or fiber contract requires, such as an NIE, the foreigner identity number. If you are staying more than six months, you also apply for a TIE within a month of entry or of your authorization (immigration law, article 4.2); that card proves your legal status, not your identity.

Signing up, switching and leaving

Before you sign. Under Ley 11/2022, the General Telecommunications Law, the operator must first send you a free contract summary, remote sales included, and for fixed internet that summary states the minimum, normally available, maximum and advertised speeds (article 67). The speed you are guaranteed is the one written in the contract, the OAUT notes. Service has to be in Spanish and, if you ask, in the region’s co-official language, with no right to English (article 65.4).

How long you are bound. A consumer contract runs 24 months at most, unless a separate installment contract covers deploying the physical line (article 67.7). You can withdraw from a distance or off-premises contract within 14 calendar days, or 30 after an unsolicited sales visit to your home (consumer law, articles 102 and 104). Any change to your conditions needs a month’s notice, and you may then leave within a month at no extra cost (article 67.8), except when the change only benefits you, is purely administrative or is imposed by law. A permanencia penalty must be proportional to the days left (consumer law, article 62.5). When the law lets you leave early, you owe only for a subsidized handset you keep, and any SIM lock is then removed free (article 67.10).

Switching. Your ported number must work within one working day of the agreed date, with no more than one working day without service, and you can still port for at least a month after the contract ends (article 70). To stop a mobile port, you ask the new operator; it is free and needs only the ID you used. The cutoff is 2 p.m. the day before the port, per the CNMC and its binding specification. No amount is given for porting delays, because the royal decree meant to set it could not be found.

Cancelling. Royal Decree 899/2009, applied where it fits Ley 11/2022, asks for two working days’ notice, and the OAUT says the operator must process your cancellation within two days and bill only until then. After an automatic renewal, Ley 11/2022 caps the notice at one month. No official page reconciles the two, so give two working days, and after a renewal refuse any demand beyond a month. The operator must take your notice through the sign-up channel or by phone, give you a reference number, and cannot refuse because you owe money.

Complaints, and the protections against scam calls

Your complaint goes to the operator first, within one month of learning of the problem (Orden ITC/1030/2007, article 4). If no satisfying answer arrives within a month, you have three months to turn to the OAUT, which then has six months to decide (OAUT complaints page). Its 2026 to 2029 charter aims for 150 calendar days. While your complaint runs, the operator can still collect the disputed bill, and once a consumer arbitration board opens a case, the OAUT route closes (Ley 11/2022, articles 65.2 and 78.2).

The operator’s month is not shortened by Ley 10/2025, the 2025 customer service law: its 15 working days for complaints and 5 days for billing ones only supplement the telecom rules. Nor does its right to be transferred to a supervisor reach operators.

You can file online with an electronic certificate or Cl@ve, which is the government login, or on paper at a Correos post office or any public registry (paper claims page). By post, the address to use is the one in the charter, whose approval was published in the BOE, the official state gazette, on July 22, 2026: C/ Poeta Joan Maragall 41, 8th floor, 28071 Madrid. The paper claims page gives Paseo de la Castellana 162 instead, and the official directory gives Calle del Mármol 2. The OAUT phones are 91 030 54 18 and 901 33 66 99, the second being a shared-cost line (numbering guide).

Scam protection. Under Orden TDF/149/2025, a call from abroad showing a Spanish number is blocked unless the phone is roaming, and mobile numbers may not be used for customer service or unsolicited sales calls. Since September 15, 2026, operators also block texts whose sender name is missing from the CNMC alias registry.

Roaming: your Spanish SIM abroad, your U.S. SIM here

In Europe. With your Spanish SIM, Regulation (EU) 2022/612 stops your operator from adding a surcharge to domestic prices anywhere in the EU. The European Commission adds Iceland, Liechtenstein, Norway and, since January 1, 2026, Ukraine and Moldova; the United Kingdom has been outside since Brexit, and for other countries it depends on your operator’s offer. Its brochure, updated January 31, 2023, also leaves out Switzerland, Andorra, Monaco and San Marino. None of them names Gibraltar or Morocco, so check your plan before you cross.

Fair use. Roaming is meant for periodic travel, so the operator may ask you for proof that you live in Spain or have stable links here. Before any surcharge, it must observe at least four months of your use, then give you at least two weeks to change your pattern (Implementing Regulation 2016/2286). The data surcharge is capped at 1.10 euros per GB before VAT in 2026, and at 1.00 euro from January 1, 2027 (Regulation 2022/612, articles 8 and 11); Your Europe, last checked January 7, 2026, still shows 2025’s 1.30 euros. The regulation is what prevails.

Spending, and your U.S. SIM. By default, a cutoff stops data roaming near 50 euros a month before VAT, outside the EU too, in the United States for instance, where the network allows it (article 14 of the 2022 regulation). A U.S. SIM used here follows your carrier’s terms, and the FCC’s travel tips (May 19, 2026) say to learn the local equivalent of 911 before you leave.

Emergencies: 112, 091 and ES-Alert

From any phone, a call to 112 costs nothing (Ley 11/2022, article 74), and the same holds across the EU. According to the national page of July 27, 2026, you need no area code, even from a foreign mobile, and calls go through from a phone with a locked keypad or no PIN entered, with an inactive SIM or outside your operator’s coverage. Cantabria and the Valencian government add that a call works even without a SIM; Catalonia (2019) says some network must be available; the FCC says some EU countries require a SIM, without naming Spain. Keep a working SIM in your phone. No official page says whether 911 reaches 112 in Spain.

Madrid answers in Spanish and English and interprets about 80 languages; Catalonia answers in Catalan, Spanish, English, French and German; Andalusia in Spanish, English, French, German and Arabic. The U.S. Embassy says to ask for an English-speaking operator, and lists 091 for the National Police along with its own number, +34 91 587 2200.

ES-Alert, the public warning system, reaches every phone in the area over 4G and 5G, with nothing to sign up for (Protección Civil). Your phone will display it on iOS 15.6 or Android 11 and later; Android 9 and 10 show it with the wrong labels, and Android 8 or older do not show it. The top level, the civil protection alert, is on by default and cannot be switched off. An alert may carry a second language, usually English, which a phone set to a language other than Spanish will display. The Canary Islands and Catalonia say tourists can get alerts if their phone is properly set up at home; no official page covers U.S. phones or SIMs.

Home internet: coverage, installation and the universal service

Coverage. On June 30, 2025, fiber reached 95.92 percent of households, 88.95 percent in rural areas, and 5G over 99 percent of the population, according to the 2025 coverage report and its summary. The ministry’s coverage page contradicts itself for that date, with 95.72 percent for fiber in its figures and 96.79 in its chart caption. Before you sign a lease, look up the address or its 14-digit cadastral reference on the fixed broadband map. The map names the operators serving each parcel (maps page), with data as of June 30, 2024, and may show a parcel as covered only because it is near a declared point; a mobile map covers 4G and 5G.

Installation. Outside the universal service, the operator must state in your contract when service will start (OAUT). In 2025, 95 percent of fixed lines were installed within 24 days in villages under 100 inhabitants, against 7 in cities over 500,000 (CNMC). You can test your line with the CNMC speed test. No official telecom price comparator turned up, even though Ley 11/2022, article 68.2 calls for one; the CNMC’s comparator covers energy only.

Universal service. Ley 11/2022, article 37 guarantees fixed broadband of at least 10 Mbps download. A reasonable request to Telefónica (Movistar) brings you a connection within 60 calendar days, and if it comes late, the monthly fees are waived automatically (ministry page); under RD 424/2005, article 29, any property on urban land qualifies, and elsewhere your habitual residence does. The draft order the CNMC reviewed caps wireless or satellite supply at 45 GB a month, and no official page shows the final order. The CNMC reported that Telefónica would be designated for 2025 and 2026, and the ministry’s April 2026 memo says the designation ends on December 31, 2026. The ministry’s out-of-date universal service page still names Telefónica as the provider until January 1, 2025.

A draft decree of April 2026 would, from January 1, 2027, raise the minimum to 100 Mbps, cut the deadline to 30 days and, where no operator is designated, oblige every operator in its coverage area (press release); it is not law. UNICO Demanda Rural funds operators to offer at least 100 Mbps for 35 euros a month where nothing else exists, covering installation and equipment up to 600 euros; its undated page does not say whether it takes new applicants. Your electricity, gas and water contracts arrive in the same first days, and the utilities guide takes them in order.

Your next step: get the phone unlocked before you fly

Before you leave, ask your U.S. carrier to lift the lock. Once you land, buy a prepaid SIM with your passport, and for a contract, bring your NIE once you have it. Any usual payment method will do (RD 899/2009, article 25), such as a direct debit from a Spanish bank account or from any euro account in the EU (SEPA Regulation, article 9). Check the coverage map before you commit to a lease, and keep every reference number. Your first month in Spain fits the phone line around the TIE appointment.

All of this is something you can do on your own, and a paper complaint needs no digital certificate. If a disputed debt goes to collection, that is the moment to talk to a lawyer or a consumer association.
