Final prices with VAT, the same every month. Subject to fibre coverage at your address. The fibre has a 12-month minimum term, tied to the free installation and router; mobile lines have none. Bundle names (Esencial, Dúo, Familia…) are the ones you will see on your contract and invoice.
*Fair use: up to 300 GB and 5,000 minutes a month per line. Beyond 300 GB the speed is reduced, and beyond 5,000 minutes each call is charged separately.

Before you start
What you need to sign up
As a registered operator we have to identify the account holder. This is what the form asks for.
🪪 An ID document
- NIE: the TIE card or the green EU registration certificate both work.
- A Spanish DNI.
- A passport: fine for fibre online. With a passport and a mobile line, we do the sign-up with you by phone, in English, in a few minutes.
You upload a photo and we fill in the form for you from it.
💳 A way to pay
- A Spanish bank account (an IBAN starting with ES) for direct debit, or
- A debit or credit card, from any country: you register it on a secure page with your bank's verification.
Nothing is charged when you sign up: we review your request and confirm with you first.
🏠 Your address in Spain
The address where we install the fibre. We check coverage there before doing anything. For mobile lines we also ask for your date of birth, because the mobile network requires it.
📱 Your current number, if you keep it
Porting your Spanish mobile or landline number is free and you are never left without a line. For a prepaid (pay-as-you-go) line we also need the ICC number printed on the SIM card. You can choose eSIM for any line.
How it works
Three steps, in English
Sign up online
Choose your bundle or build your own and fill in the form in English. It takes about ten minutes.
We call you
We check coverage at your address and call you, in English, to confirm everything before activating anything.
Installation and SIM cards
A technician installs the fibre and the router at no cost, and we post your SIM cards (or email the eSIM). If you are bringing your numbers, the switch happens without losing service.
FAQ
Questions we often get
Can I sign up without an NIE?
Yes. With a passport you can sign up for fibre online. If you also want a mobile line, we do the sign-up with you by phone, in English: call +34 854 78 34 00.
Do I need a Spanish bank account?
No. Direct debit needs a Spanish IBAN (starting with ES), but you can pay with a debit or credit card from any country instead.
Is the contract in English?
The contract, the terms and the invoices are issued in Spanish, which is the legally binding version. We are happy to explain any part of them in English before you sign.
Can I keep my Spanish phone number?
Yes. Porting is free, line by line, for mobiles and landlines, and you are never left without service.
Which mobile network do you use?
The bundles run on Vodafone's network. SIM-only lines can be on Movistar or Vodafone coverage: the same coverage you would get signing up with them.
Is there a minimum term?
Mobile lines have no minimum term. Fibre has 12 months, tied to the free installation and router: if you leave earlier, only the proportional part of that cost is charged.
Do the prices include VAT?
Yes. Every price on this page is the final price with VAT (IVA) included.
Can I call abroad?
Yes. You can add an international calls bundle of 100 or 300 minutes a month to a line on Movistar coverage.
Do you cover my town?
We sell throughout Spain, but fibre depends on the exact address. The sign-up form checks it with your street and number, or send us your address on WhatsApp and we check it for you.
