Phone and internet: what works on day one, and when contracts start

Terms used

• NIE — The NIE is the identity number Spain gives to foreigners, used in contracts, tax and banking.
• TIE — The TIE is the foreign-resident card that shows your NIE.
• IBAN — The IBAN is your bank account number, used by operators to take monthly payments by direct debit.
• Padrón — The padrón is the town hall register of where you live; its certificate proves your address.
• Permanencia — The permanencia is the minimum term of a contract, with a penalty if you leave before it ends.

Key rules

• Prepaid: A prepaid SIM or eSIM needs no Spanish bank account, only registration with your passport, national ID card or NIE.
• Contracts: Monthly contracts usually need ID plus a Spanish IBAN, and each operator sets its own checks.
• Data-only eSIM: Travel data-only eSIMs need no Spanish ID, so they cover your first days.
• Minimum term: Home internet often carries a 12-month minimum term with a penalty for leaving early.

What works on day one

A prepaid SIM or an eSIM works on day one. A monthly contract usually takes longer, because it needs ID and often a Spanish bank account.

You can buy a prepaid SIM (tarjeta prepago) or eSIM from the main operators. Look in airport shops, operator shops, kiosks, supermarkets or online. You do not need a Spanish bank account. You can top up by card or cash.

Spanish law requires every prepaid line to be registered to a named holder. Use your passport, national ID card or NIE. You can register in the shop or in the operator's app. Activation can take anywhere from a few minutes to a few hours, so buy before you need the line.

Many travel eSIM providers sell data-only eSIMs that need no Spanish ID. They are a good bridge for your first days. Some operators, such as Digi, activate an eSIM in their app with a photo of your ID.

What needs an identity number and a bank account

Monthly mobile and home internet contracts are the harder part. Expect the operator to ask for:

• Valid ID: a passport, an EU ID card or a NIE/TIE. Non-EU customers without a NIE can often sign with a passport, but some operators also ask for a NIE or proof of residence.
• A Spanish bank account IBAN for direct debit (domiciliación). Some operators accept a foreign SEPA IBAN or card payment. Policies differ, so ask.
• A Spanish address for billing. A declared address is often enough. A padrón certificate or a utility bill is only asked for sometimes.

For handset financing or multi-line packages, operators run credit checks. With no Spanish credit history, they may ask for a deposit or refuse the contract. If one operator refuses, try another, or stay on prepaid until you have your NIE and a bank account.

Home internet: plan for the wait

Home internet is not a day-one service. Check that your address has fibre coverage before you sign. The installer also needs your right to live there, so you may be asked for your rental contract or proof of address. Many operators accept just a declared address.

Installation usually takes 3 to 10 working days if a fibre line already exists. If a new line or building access is needed, it can take 2 to 4 weeks. Book as soon as you have the keys, and use mobile data meanwhile.

Contracts commonly have a 12-month minimum term (permanencia). Leaving early usually means a penalty. Ask for the term and the exit penalty before you accept.

The documents list, checklist and timeline below carry the step-by-step detail.

Timeline and deadlines

• Check that your address has fibre coverage and choose an operator: before you sign

• Installation when a fibre line already exists at the address: typically 3 to 10 working days after signing

• Installation when a new line or building access is needed: 2 to 4 weeks after signing

• Minimum term (permanencia) with penalties for leaving early: commonly the first 12 months of the contract

Documents you need

• Valid ID for any contract: a passport, an EU ID card, or a NIE/TIE (your foreign-resident number or card). Non-EU customers without a NIE can often sign with a passport, but some operators ask for a NIE.

• ID to register a prepaid SIM or eSIM: a passport, national ID card or NIE. Data-only travel eSIMs need no Spanish ID.

• A Spanish bank account IBAN for direct debit on mobile and home internet contracts. Some operators accept a foreign SEPA IBAN or a card payment.

• Proof of address, such as a padrón certificate (the town hall registration of where you live), a utility bill or a rental contract. Operators ask for it only sometimes, and many accept a declared address.

Checklist

• Buy a prepaid SIM or eSIM for day one at an airport shop, operator shop, kiosk, supermarket or online.

• Ask the operator whether it accepts your passport alone for a monthly contract or also wants a NIE.

• Ask whether the operator accepts a foreign SEPA IBAN or card payment if you have no Spanish bank account yet.

• Confirm fibre coverage and the installation lead time for your address before you sign a home internet contract.

What to watch out for

• Contract refused or deposit asked: Some operators refuse a postpaid mobile or home internet contract if you have no NIE, no Spanish IBAN or no Spanish credit history. Others ask for a deposit, especially for handset financing or multi-line packages. Start with a prepaid line, then ask a different operator, or ask whether a foreign SEPA IBAN or card payment is accepted.

• Minimum term with penalties: Home internet contracts commonly carry a 12-month minimum term (permanencia), and leaving early means a penalty. Ask for the minimum term and the exit penalty in writing before you sign, and check that you will stay at the address that long.

Frequently asked questions

Can I get a Spanish SIM without a NIE?

Yes, you can usually register a prepaid SIM with just a passport or an EU national ID card. Spanish law requires the line to be registered in your name.

Do I need a Spanish bank account for a prepaid SIM?

No, a Spanish bank account is not needed for a prepaid SIM. You can top up by card or with cash. A Spanish IBAN only matters later, when you sign a monthly contract paid by direct debit.

What if an operator refuses my home internet contract?

Yes, this can happen if you have no NIE or no Spanish IBAN, because some providers decline the contract or ask for a deposit. Try another operator, since policies differ.

How long does home internet installation take?

Installation usually takes 3 to 10 working days when the fibre line already exists. It can take 2 to 4 weeks if a new line or building access is needed. Ask the operator which case applies to your address.
