Looking for an internet provider

You can place yourself on the waiting list for Starlink in Spain (see link).  Meanwhile, you could use cellular internet via an iPad, phone, or dedicated hotspot.  I see that Spain does have unlimited data cellular available.

Since the link in my original answer hasn't been approved yet, google "Starlink Spain" and you'll see your first option.  For your second option, google "wifiaway" (one word), which is actually a very convenient option for those who just need temporary internet access while waiting for a permanent installation.

Thanks Lewis, do you know when Starlink is due to be up?

hI, you can get a mini portable modem in a bigger city if you are out in the sticks. Nowadays, cell phone providers work off the satellites, not the towers. If you can, travel to Madrid, Barcelona etc and get your provider there. And get their dedicated mini modem with unlimited data chip.

You can get the exact same hotspot (mini portable modem) through WifiAway, along with an extended battery pack.  While it's true that the newer 5G millimeter-wave technology uses microwaves, it does not utilize satellites (as in orbiting the Earth).  If cellular used satellites, it would be unusable inside a home or parking garage (no line-of-sight to the sky).

Last I heard, several friends here in the US already had Starlink, including one friend who is using it in a camper (motorhome) and another in their boat.  You should add yourself to the waiting list, because it is first-come first-serve.

In addition, I've done many things (here in the US) to obtain high-speed internet in places that were lacking it.  As long as there is a location within eyesight (as in a home which your eyes can see from the roof of your home) that has internet access, there is hope for you yet!

For example, my community only recently got fiber, and because I'm on a lake, cable and DSL was unreliable.  So I purchased a point-to-point microwave link (5 GHz), set one up on my rooftop and the other at a friend's home 8 km away.  I offered to pay for half his internet bill, which he was very happy about.  In return, I now had reliable high-speed service through his home, right into my home.  This is called "back haul."

For short range (up to 2 kM), you can use a low-power bridge like this.  For longer range (8 kM), you can use one of many point-to-point dish setups.  Telecommunications is my hobby... I've been a ham (amateur) radio operator for 40+ years.
