Unfortunately, it is pretty hard to have a contract for Fiber Internet connetion with most of the providers without a NIE card. I suggest you to start with Movistar Fiber Internet without contract package and change to another provider after receiving your NIE card.
If you need a extensive mobile data plan during your first days without fiber Internet, I suggest you going with Simyo which uses Orange as backend and provides 25GB 4G Internet connection for €28. In Movistar mobile, you can get only 2.8 GB with this amount of money. You can visit a tienda (shop) and get the SIM card for €10. Then you can load Internet and call packs on the control panel. If you don't have an existing Internet connection, you may ask for the representative.
We came to Madrid, Spain to work for Amazon and applied for our NIE card on 25.07.2017. Our appointment had been arranged for us before our arrival. We were told it may take 1 - 1.5 month for the card to be ready and given a stamped document indicating we've applied for the card and currently on hold. This document was supposed to be a temporary NIE card. Because it contained the essential information like expiry date and NIE number. We also had our NIE numbers on our visa (passport page).
Failing attempts for fiber contract application
After finding a flat in Madrid, we applied for the Fiber connection and 2 mobile lines (to be moved from Movistar) on Vodafone's web site on 06.08.2017. They called us back the following day (07.08.2017) and asked the same information again on the phone (the call was in English). Then I received an email indicating another application was registered than the one I applied the previous day. On 08.08.2017, someone else called me and told me that Vodafone asks for €500 as assistance fee and it would be better for me to go to a tienda (physical Vodafone store). I went to a tienda in Delicias and they told me to wait the men who will come for the installation and they will bring the contract. But I didn't trust his words. The next day (09.08.2017), I went to the tienda in El Corte Ingles, Paseo de la Castellana. I provided my temporary NIE document, my passport / visa copy, my work permit. The saleswoman asked her boss and the next day (10.08.2017) told me they can not accept the application without physical NIE card. So I went to Orange store near Puerta del Sol. They told me the temporary document is invalid and they can not make a contract! So after recommendation of my friend, I went to Vodafone in Puerta del Sol and they accept the documents I provided and take notes on it and sent me because they were closing.
The other day (11.08.2017) Puerta del Sol tienda of Vodafone called me and asked me my IBAN number (for automatic payment). I provided the number and could not get a response until 16.08.2017, when I received a call in Spanish, saying I have to go to the tienda to sign the contract. So I went to the tienda in Puerta del Sol. After waiting for 40 minutes, I was told my contract was cancelled by Vodafone due to the need of €500 deposit. They cancelled it without giving me a chance to pay the deposit (which is kind of insult for me). Also there were 4 applications on behalf of me and all of them were cancelled. I lost many hours dealing with these problems.
It's so strange that the modem they'll be giving doesn't worth €500 and I'll be paying the bills every month and I work for Amazon with indefinite contract. One of my friends paid this amount but could not get the connection to be installed for a long time. One other friend did not sign the contract but gave his bank account details and he was charged. Luckily, he could get his money back.
Applying for Movistar Fiber-only
On 20.08.2017, I applied for Movistar online, they asked for NIE and IBAN. The next day, they called me and told me I had to reside in Movistar for 45 days to apply for a contract and they could offer me Fiber-only package without contract. I accepted. On 23.07.2017, the technician came and installed the fiber cable and the modem. They even didn't ask for my passport or NIE card! It's now working properly but asymmetrical (50/5 Mbps) for now.
Applying for Movistar contract (AVOID)
On 16.09.2017, I applied for Fusion Series contract plan online, providing 50 Mbps symmetric fiber, 4 GB Internet and TV plan. It was €45 for the first 3 months and €60 afterwards without commitment. Only you have to stay for 3 months to avoid €187 installation fee to be charged. This time I had to provide them the fixed line number (given to you on a paper by the technician or written on the control panel) as well in the form. After filling the form, Internet connection changed to symmetric in a few minutes and mobile plans were activated upon restarting the phones. On the phone call last month, I was told (my friend translated) that data plan would be 4 GB and could be share among the two mobile lines. However, that was not the case. It was just for the first line. The second line was limited to 200 MB and stopped working afterwards (or worked very slowly). I had to purchase a plan of 2 GB for that as well with an extra €10 / month. Then I realized I was being charged €90-120 each month as if I did not have any package plan (Fusion Series #0). I learned that some other expats had the same situation.
Applying for Orange contract
After 5 months, on 28.02.2018, I decided to move on Orange. I went to a shop and filled the form for "Love Familia Esencial" which is €66 / month for 50Mbps Fiber + 2 mobile lines with 200 minutes and 8GB in total. They gave me 2 SIM cards and on wednesday, Movistar called us several times, coming up with a counter-offer. I rejected. On thursday Orange called and came to install their modem and the fiber line and landline phone was working. The next day (friday), our mobile lines also migrated to Orange.
However two mobile lines were not working. The English speaking staff was not professional (did not speak English well) and could only tell me "restart your phone, if it doesn't work, go to a Orange shop". I was connectionless all the day! On saturday, the shop decided the sim cards was broken and replaced them and they worked!
After a while, I logged in "Mi Orange" control panel using phone authentication and I saw that
- my mail address was recorded wrong: email@example.com (possibly violated my privacy by sending my account details to someone else)
- they chose the second mobile line as the contact number, not the first one (which I set as contact number).
- my address only had street number. No floor / door number whatsoever.
- when I set a password (had to be alphanumeric and between 6-8 characters), it was sent to me via SMS in plaintext format! How secure! It did not allow me to login with that password, forcing me to use 6-8 digit password.
As you can see, almost all of the experience is broken. The bad thing is that the contract was under the condition of 12 months permanence.
The only nice thing was that it allowed for international calls using a special plan.
Recommendation for Package Contract
Try to have a contract in a shop, with a price written on the contract instead of comfirming whatever is said on the phone. Almost all of the Internet providers cause trouble, so be prepared for that!
