Making your internet reliable enough for remote work

Key rules

• Speed: Plan for at least 10 Mbps down and 5 Mbps up, and 30 Mbps or more if several people share the line.
• Coverage: Check the exact address and floor with operators before signing a lease, since the national map is less precise.
• Backup: Set up and test a second connection at the flat before you rely on it for a call.
• VPN: Using a VPN is legal in Spain, but banks, government sites and streaming services may block it.
• Outage claims: Send the operator a written claim; it must answer within one month, then you can go to the telecoms user office.

What speed you need

For stable work calls, plan for at least 10 Mbps down and 5 Mbps up. If several people share the line, aim for 30 Mbps or more. Video calls on the main work tools need roughly 1 to 4 Mbps each way, so calls are rarely the problem. Large uploads (files, video, backups) depend on upload speed.

Most Spanish home fibre plans are symmetric, commonly 300 Mbps to 1 Gbps both ways, so uploads are usually fine. ADSL, radio and mobile connections are often slower and uneven. A stable, low-delay line matters as much as the headline speed.

Check coverage before you sign a lease

Fibre is widely available in Spain, but rural areas and small, scattered villages have less of it. Check the exact address before you commit to a flat.

Do it in this order:

1. Use the Ministry for Digital Transformation's coverage viewer to see which technologies reach the address.
2. Then use the operators' own checkers with the full address and floor. They are more accurate for a specific flat than the national map.
3. Look at each operator's mobile coverage map, because it decides whether a mobile backup will work.
4. Ask the landlord or neighbours which operator works in the building and whether a fibre socket (roseta) is already installed.

Plan for install delays

Where the building already has fibre, installation usually takes 2 to 7 days after you order, and often 24 to 72 hours with the main operators. If a technician must lay new cable or activate the line, allow 1 to 3 weeks.

Delays are more likely in older buildings with no fibre in the common areas, where the comunidad de propietarios must approve works, in rural areas, after a missed technician visit, and in September and January. Changing operator and keeping your number (portabilidad) can add a few days. Do not schedule an important call for the first days after you move in. The utilities page covers how to contract the line.

Set up a backup link

Have a second way online before you need it. The usual options are:

• Phone hotspot: use a mobile plan with plenty of data. It is the cheapest start.
• 4G/5G router: a portable or fixed router with a data-only SIM. It is a one-off purchase plus a monthly plan.
• Second fixed line: a line from a different operator. It costs a monthly fee, often with an installation charge and sometimes a minimum term.

Prepaid and low-cost data SIMs are widely sold. Check current prices with the operators. A mobile backup is only as good as the local 4G/5G signal, and you should test it at the flat before relying on it for a call.

If your internet goes down

Report the fault to the operator and keep the reference number. Then send a written claim to its customer service. The operator must answer within one month. Operators must compensate you for outages, and your contract usually states how.

If the answer is unsatisfactory or missing, complain to the telecoms user office (Oficina de Atención al Usuario de Telecomunicaciones), normally within 3 months of the operator's reply. After that you can go to consumer arbitration, your regional or town consumer office, or the courts. Business contracts may follow different terms.

VPNs: legal, but sometimes blocked

Using a VPN is legal in Spain, whether it is your company's or a personal one. Illegal activity stays illegal through a VPN.

Blocking is the practical issue. Streaming services, banks and government sites such as Cl@ve, the tax agency and Social Security may block or flag VPNs or foreign addresses, or ask for extra checks. Work tools like Slack, Zoom, Teams and Google Workspace generally work, though your company may restrict logins from unexpected countries. Choose a VPN with a Spanish server, switch servers when blocked, and turn it off for banking or government portals that refuse access.

Court-ordered blocks aimed at football piracy sometimes affect ordinary connections. A VPN can get around them, but you should not rely on that for work.

The checklist, timeline and warnings below cover the steps and the common traps.

Timeline and deadlines

• Fibre installation where a technician must lay new cable or activate the line: 1 to 3 weeks after ordering

• Allow extra time if you change operator and keep your number: a few extra days

• Operator must answer your written outage claim: within one month of your claim

Checklist

• Enter the address in the Ministry for Digital Transformation's coverage viewer to see whether fibre, radio, 4G or 5G reach it.

• Enter the full address and floor in the coverage checkers of the main operators to see whether fibre can be installed there.

• Check each operator's mobile coverage map for the address.

• Choose a backup: a phone hotspot with plenty of data, a 4G/5G router on a data-only SIM, or a second line from a different operator.

Operator checkers and prices change, so confirm them for your address.

What to watch out for

• Streaming, banking and government sites may block your VPN: Many streaming services block known VPN addresses. Banks, payment apps and government sites such as Cl@ve, the tax agency and Social Security may block foreign IPs or ask for extra checks.

• Your company's security policy may reject logins: Work tools like Slack, Zoom, Teams, Google Workspace and GitHub generally work with VPNs, but a company policy can restrict logins from unexpected countries or addresses. Ask your IT team to approve your Spanish connection and VPN before your first working day there.

• A VPN does not make illegal activity legal: A VPN is legal in Spain, but copyright infringement or fraud stays illegal through one. Court-ordered blocks on football piracy can also catch ordinary users' connections. Use a VPN only for work and privacy, and expect some sites to be unreachable during blocked matches.

Frequently asked questions

How long does fibre installation take in Spain?

Fibre installation takes about 2 to 7 days when the building already has fibre, and often 24 to 72 hours with the main operators. If a technician must lay new cable, allow 1 to 3 weeks. Older buildings, rural areas and moving seasons in September and January can add delays.

Is it legal to use a VPN in Spain for remote work?

Yes, using a personal or corporate VPN is legal in Spain, but illegal activity stays illegal when done through a VPN. Some football piracy blocks ordered by courts can affect ordinary connections, though using a VPN is not an offence.

What can I do if my internet is down for days?

Report the fault to your operator and keep the reference number, then send a written claim to its customer service, which must answer within one month. Operators must compensate for outages. If you get no answer, you can complain to the telecoms user office of the Ministry for Digital Transformation, normally within 3 months of the operator's reply.

How much speed do I need for video calls and big uploads?

Plan for at least 10 Mbps down and 5 Mbps up for stable work calls, and ideally 30 Mbps or more if several people share the line. Most Spanish home fibre plans are symmetric at 300 Mbps to 1 Gbps, so uploads are rarely a problem.
