Which internet service provide is best in Spain? | Telecom Consumer Discussion Forums

For stays superior to 12 months: Movistar is the best option if you know that you are relocating to Madrid for more than 1 year:

    Movistar: get the best quality possible, go for optical fiber (100 Mb instead of 20!), with the new offer of Movistar Fusion, which includes also 500 Min & 1GB data on your mobile for 72,48€ a month.
    If you want cable TV with it with more than 80 channels, add 24,20 € per month
    If you want an additional mobile line with 500 minutes and 1 Gb per month, as well as unlimited text messages, add another 24,20 € per month.

b) if you only have a passport – Ono
    36,28 €/month for 12 Mb, no commitment, then after 6 months, 48,08 €.

In the end, if you want to keep the promotional price, you just have to call your provider to ask them for a renewal, and or just tell them that you are going to Orange, and they will renew you the promotional price in 90% of the cases.
Yes, you can get the Ono packages with a passport and without a NIE, but not by the online form – only by calling. They do speak English if you ask for it.
