Types of internet connection in Spain: fibre, ADSL, fixed 5G and satellite

Before comparing operators and prices, it pays to know what kind of internet connection you'll actually be signing up for. Four real technologies coexist in Spain in 2026 — fibre (FTTH), ADSL, fixed 5G and satellite — and the gap between them is huge, far bigger than the gap between operators. This guide explains when each makes sense, what real-world speed to expect and where prices land in each category.

Fibre to the home (FTTH): the default if you have it

FTTH (Fibre To The Home) runs a glass cable straight from the operator's central office to your address. It's the only technology that delivers real speeds of hundreds of Mbps to gigabit per second today, with upload nearly equal to download.

• Typical speeds — 300 Mbps, 600 Mbps and 1 Gbps symmetric. Some operators already sell 2 Gbps and 10 Gbps in premium areas.
• Latency — usually 5 to 15 ms to European servers. Excellent for video calls, online gaming and remote work.
• Stability — very high: fibre cable doesn't suffer from interference and serious outages are rare. Speed barely varies with time of day.
• 2026 prices — from €29.90/month (entry plans like MiMobile Red Fiber 300 Mb with no lock-in) up to €50-60/month for fibre 1 Gbps + mobile packs with unlimited calls.

When to pick it: whenever it's available at your address. FTTH coverage in Spain now exceeds 90% of households according to CNMC figures, but pockets remain where it hasn't reached — small villages, isolated houses, some older urbanisations.

ADSL: why it still exists in 2026

ADSL uses the copper telephone pair to deliver internet. It's what Spain had through the 2000s and 2010s, and it remains the only wired option at addresses where fibre hasn't arrived.

• Typical speeds — 5 to 30 Mbps real download depending on distance to the exchange. Typical upload between 0.5 and 3 Mbps (very asymmetric).
• Latency — 25 to 60 ms. Acceptable for browsing, tight for video calls when upload reaches 1 Mbps.
• Stability — depends on the state of the copper pair, which in some rural areas is decades old. Micro-outages common during storms and evening peak hours.
• 2026 prices — €20 to €30/month, paradoxically not much cheaper than entry-level fibre. Copper has high fixed maintenance costs.

When to pick it: when it's the only wired option. If fibre is available there's no reason to sign up for new ADSL in 2026 — it costs the same and gives a fraction of the speed. Telefónica announced a phased copper switch-off years ago, but the process is still active and varies widely by municipality.

Fixed 5G: the real alternative when fibre doesn't reach

Fixed 5G (also called FWA, Fixed Wireless Access) uses the operators' 5G network to deliver home internet through a router with a SIM. The signal comes in via a rooftop antenna or directly to the router if you have good window coverage, and is distributed by WiFi just like normal fibre.

• Typical speeds — 100 to 600 Mbps real download with good 5G coverage; upload between 20 and 80 Mbps. With only 4G+ coverage the figure drops to 30-100 Mbps download.
• Latency — 20 to 50 ms on 5G; 40 to 80 ms on 4G. Enough for normal use, tight for competitive gaming.
• Stability — variable. Speed fluctuates with cell congestion (worst between 20:00 and 23:00) and weather.
• 2026 prices — €30 to €45/month from Movistar, Vodafone, Orange and MasMovil fixed-5G offers. The router is usually included in the fee.

When to pick it: when there's no fibre available and 5G (or at least 4G+) coverage at your address is good. Also as a temporary solution while you wait for fibre, or for second homes where you don't want to pay fibre install + lock-in.

Satellite internet: Starlink and the rest

Satellite internet sends and receives data between a dish on your property and satellites in orbit. Until a few years ago the only options were slow and very expensive (HughesNet, ViaSat) with terrible latency. Starlink (SpaceX) in low orbit changed the picture: today satellite is a real option for areas where neither fibre nor decent mobile signal reach.

• Starlink — typical real speeds 100-300 Mbps download, 10-40 Mbps upload, latency 25-60 ms. Current Spanish monthly fee around €50-65/month (residential and roam plans). Antenna + router kit around €350-400 up front.
• HughesNet / ViaSat — traditional geostationary satellite. Nominal speeds 25-100 Mbps but with 600+ ms latency (satellites sit at 36,000 km altitude). Only recommended where Starlink doesn't have coverage.

When to pick it: you live in an isolated house with no fibre and weak mobile coverage (poor mobile signal rules out fixed 5G). Starlink is the reasonable option in the category except in very specific cases. For second homes used only a few months a year, a generous data SIM with a 4G/5G router usually pays back better than leaving Starlink sitting idle the rest of the time.

Quick comparison: which to pick for your situation

How to check what's available at your address

General-purpose comparators often get it wrong — real coverage depends on the exact building, and sometimes on the floor. The honest steps:

1. Operator coverage checker. Movistar, Vodafone, Orange, MasMovil and Digi all have online checkers where you enter street, number and entrance. Start with two or three to cross-reference — if one says "no fibre" that doesn't mean no operator has it.
2. Ask the concierge or a neighbour. If you see a fibre router in the entrance or cables going to other flats, your building almost certainly already has fibre installed by at least one operator.
3. 5G coverage map. If fibre doesn't reach, next check the operator's 5G coverage to see if fixed 5G is viable. Official maps are indicative — real coverage depends on orientation, walls and floor.
4. Ask us, no strings attached. If you want a second opinion, message us on WhatsApp (+34 694 465 169). We'll check real coverage at your address across several operators before you sign anything — free.
