Internet from Altibox: Service Overview
Altibox is a well-established provider of fiber broadband in Denmark. They are known for consistently ranking high in customer satisfaction surveys, often cited as having “Denmark’s best internet” by the Loyalty Group. Unlike budget providers that focus solely on price, internet from Altibox positions itself as a premium service with a focus on connection stability, high-quality hardware, and customer support.
The company operates exclusively on fiber networks. This means they do not offer internet via old telephone cables (DSL) or cable TV coax networks. By focusing purely on fiber-to-the-home (FTTH), they ensure that all customers receive symmetric speeds, where upload rates match download rates. This technical focus eliminates many of the congestion and latency issues associated with older infrastructure.
Altibox provides services to a large portion of Denmark through partnerships with various infrastructure owners. While they originally started with a strong presence in specific regions like Mid and West Jutland, they have expanded their reach significantly. Residents in many parts of the country can now access their services, provided there is an active fiber line installed at the address.
Speeds and Pricing
Altibox offers a simplified structure for their internet speeds. Most customers choose between a capable entry-level connection and a high-speed gigabit connection. The pricing model typically involves a discounted introductory rate followed by a standard monthly price. In Denmark, internet contracts for consumers have a maximum binding period of six months.
The following table outlines the typical fiber plans available from Altibox based on current market offers. Note that availability depends on the specific fiber network owner in your area.
| Speed (Down/Up) | Intro Price | Standard Price | Binding Period | Ideal For |
| 100/100 Mbit | 99 kr/mo | 309 kr/mo | 6 months | Small households, streaming, browsing |
| 1000/1000 Mbit | 139 kr/mo | 399 kr/mo | 6 months | Large families, heavy gaming, large downloads |
The prices listed above often reflect specific campaigns. For example, the 1000/1000 Mbit plan may be offered at 139 kr/month for the first 12 months, despite the binding period ending after 6 months. It is important to check the specific terms during the sign-up process, as the standard price of 399 kr/month applies once the discount period expires.
Installation fees can vary. In many campaigns, the creation fee (oprettelse) is waived (0 kr). However, if a new fiber line needs to be dug into the property, substantial extra costs may apply. This is usually determined during the address check.
Fiber Technology and Infrastructure
Altibox delivers internet exclusively via fiber optics. This technology uses light signals to transmit data, resulting in significantly higher capacity and lower latency compared to copper-based networks. For users, this translates to a responsive connection that does not slow down during peak evening hours.
Symmetric speeds are a key feature of fiber internet in Denmark. If you subscribe to a 1000 Mbit plan, you receive 1000 Mbit for both downloading and uploading. High upload speeds are essential for video conferencing, cloud backups, and sending large files. This contrasts with cable internet (coax), where upload speeds are typically only 10% to 20% of the download speed.
Altibox utilizes the OpenNet platform to reach customers. This allows them to deliver services on fiber networks owned by other utility companies, such as Norlys, Fibia, and OneFiber. Consequently, you do not need to live in an area where Altibox owns the cables physically; you only need to live in an area where their partner networks have coverage.
Availability and Address Checks
Determining if you can get Altibox requires an address lookup on their website. The Danish telecom market relies on a central database of address availability. When you enter your address, the system checks which physical cables enter your property and whether Altibox has a service agreement with the infrastructure owner.
If fiber is already installed in your home, activation is straightforward. A fiber termination box (ONT) should already be mounted on a wall inside the house. If the previous resident had an active line, Altibox can often activate the signal remotely within a few weeks or even days.
If your area has fiber in the street but not into your specific house, you may need to order a “dig-in” installation. This involves a technician running a cable from the street to your house and drilling a hole through the wall to install the equipment. This process takes longer, typically between 4 to 8 weeks, depending on permits and technician availability.
Installation and Hardware
When you subscribe to Altibox, you generally receive a premium router included in the subscription or for a small rental fee. Altibox is known for supplying high-quality hardware, often from manufacturers like Icotera or Nokia. These routers are designed to handle gigabit speeds over Wi-Fi, although achieving full speed always requires a wired Ethernet connection.
The Fiber Box (ONT) vs. The Router
It is important to distinguish between the two pieces of equipment involved in a fiber connection. The Fiber Box (Optical Network Terminal or ONT) is a small white box permanently fixed to the wall where the fiber cable enters the house. This unit converts light signals into electrical signals. It belongs to the infrastructure owner and must not be removed when you move.
The router connects to the Fiber Box via a LAN cable. The router creates your Wi-Fi network and manages local traffic. If you prefer to use your own high-end router or a mesh system, you can often set the Altibox router to “Bridge Mode” or connect your own router directly to the Fiber Box, depending on the specific network configuration.
Wi-Fi and Mesh Systems
For larger homes or houses with thick concrete walls, a single router may not provide sufficient coverage. Altibox offers mesh Wi-Fi solutions, sometimes branded as “Premium Wi-Fi.” These are additional satellite units that place Wi-Fi signals throughout the house to eliminate dead zones. These units usually come with an additional monthly rental fee.
Sign-up Process and Requirements
Signing up for internet services in Denmark follows a standardized digital process. To become a customer with Altibox, you must have a Danish CPR number (civil registration number). This is used for identity verification and credit checks.
The sign-up flow requires authentication via MitID. MitID is the national digital ID system used for banking and government services. This ensures that the contract is legally binding and linked to the correct individual. If you have recently arrived in Denmark and do not yet have MitID, you may need to contact their customer service via phone to arrange an alternative registration method, though this is becoming less common.
During the sign-up, you will select your payment method. The most common method is Betalingsservice (PBS), which automatically deducts the bill from your bank account. Using manual invoices (Girokort) often incurs a substantial administration fee (typically around 49 kr per bill), so setting up automatic payment is highly recommended.
Contract Terms and Consumer Rights
Danish telecommunications law provides strong consumer protection. When you sign a contract with a binding period, it cannot exceed six months. After the binding period expires, you can cancel the service with one month’s notice. This applies even if you are on a 12-month discount plan; the price may increase after the discount, but you are free to leave after month six.
If you move address, you cannot simply take the connection with you without notifying the provider. You must check if Altibox can supply the new address. If they can, the contract typically continues. If they cannot supply the new address (for example, if you move to an area with only coax cabling), you have the right to terminate the contract, usually with the standard one-month notice.
Altibox also offers a “satisfaction guarantee” on some subscriptions. This allows customers to cancel within a short window (e.g., 14 or 30 days) if the service does not meet expectations, without being held to the full binding period. Always read the fine print to see if this applies to your specific offer.
Comparing Altibox to Competitors
The Danish internet market is competitive. When considering internet in Denmark, it is useful to compare providers based on more than just price. Altibox generally sits in the premium segment. Their standard pricing (309-399 kr) is higher than budget providers like Fastspeed or Jetnet, which often charge around 249-289 kr for similar speeds.
The difference lies in the service bundle. Budget providers typically offer a “raw” internet connection with basic support. Altibox includes a higher level of customer service and often better included hardware. Additionally, Altibox offers traditional TV packages and streaming bundles, which many budget internet providers do not.
For users in major urban areas, you might compare Altibox with internet in Copenhagen providers like Hiper. While Hiper utilizes both coax and fiber to reach maximum coverage, Altibox sticks strictly to fiber. This means Altibox has lower total coverage but a more consistent technology baseline.
TV and Entertainment Bundles
Altibox is a “triple-play” provider, meaning they can supply internet, TV, and landline telephony (though landlines are rare today). Their TV packages are delivered via the internet connection (IPTV) or via an app. This is convenient for households that want a single bill for all digital services.
The TV packages range from basic local channels to extensive packages including sports and international channels. They also offer “Choose Yourself” options where you can pick specific streaming services (like TV2 Play or Viaplay) to include in your subscription. This integration can sometimes offset the higher cost of the internet subscription if you were planning to pay for these services separately.
Customer Service and Self-Service
Customer support is a primary selling point for Altibox. They offer telephone support with reasonable opening hours, as well as email and social media support. For technical troubleshooting, they provide extensive online guides tailored to the specific routers they supply.
Customers have access to “Mit Altibox” (My Altibox), a self-service portal. Here, users can view invoices, change payment details, and modify their subscriptions. It is also where you can monitor your current operational status and check for any network outages in your area.
Technical Considerations for Gamers and Power Users
For gaming, latency (ping) is often more important than raw bandwidth. Because Altibox uses fiber, the latency is typically very low, often between 2ms and 10ms to local Danish servers. This provides a significant advantage over 4G/5G mobile broadband or older copper connections.
Users running home servers or advanced network setups should be aware of public IP addresses. Some internet providers use CGNAT (Carrier-Grade NAT), which shares one public IP address among many users. This can complicate port forwarding. Altibox generally provides a dynamic public IP address, but it is worth confirming if you require a fixed static IP, as this usually costs extra.
If you are looking for internet from Norlys, you might find that Altibox is actually delivering the service over the Norlys fiber cables. In this scenario, the physical line is maintained by Norlys, but billing, router support, and customer service are handled by Altibox. This separation of infrastructure owner and service provider is standard in Denmark.
Summary of Pros and Cons
Advantages
The primary benefit of Altibox is the stability of the fiber connection. Symmetric speeds ensure that cloud backups and video calls are seamless. The included hardware is generally of a higher specification than budget competitors, reducing the need to buy your own router. Their customer service reputation is also a safety net for less technical users.
Disadvantages
The main drawback is price. The standard monthly fee is higher than the market average for bare-bones internet. Additionally, availability is strictly limited to addresses with fiber access. If you live in an older apartment building in a city center that only has coax cable (cable TV network), you cannot get Altibox.
Final Installation Tips
When your installation date arrives, ensure someone is home if a technician visit is scheduled. If you are doing a self-install (activation only), you will receive the router by mail or pick it up at a parcel shop. Connect the router to the ONT using the provided cable—do not use old cables from previous installations, as they may not support gigabit speeds.
Place the router centrally in your home and off the floor. Fiber speeds are incredibly fast, but poor router placement can reduce Wi-Fi performance by 50% or more. If your home is larger than 120 square meters, consider ordering the mesh solution immediately to avoid coverage frustration.
