Mobile: SIM-only, prepaid or a contract with a handset
Dutch telecom providers must give you a clear contract summary before you sign any mobile agreement. This document outlines the network quality, internet speed, duration, fixed charges, out-of-bundle rates, and early cancellation fees. You can choose between prepaid cards, a SIM-only plan, or an abonnement (subscription) that includes a mobile handset. If you buy a plan with a phone, the monthly fee splits into a subscription portion and a device repayment portion.
Contracts signed online, by phone, or on the street carry a statutory 14-day bedenktijd (cooling-off period). Within these two weeks, you can cancel the deal without giving any reason. Every telecom company publishes a coverage map on its website showing where 3G, 4G, or 5G functions across the country. Check these maps for your home address and your workplace before committing.
Out-of-bundle costs can climb rapidly if you exceed your monthly data or call minutes. Dutch law requires providers to notify you by text message or app alert whenever your bundle is nearly or completely empty. Some providers let you activate a data limit that stops all internet traffic once your allowance runs out, preventing unexpected costs. Other plans allow you to adjust your bundle monthly or roll over unused minutes and data to the next billing cycle. Look closely at rounding rules: certain operators round calls to full minutes or data sessions to full megabytes, which exhausts your allowance faster than anticipated.
Inside the European Union, standard roaming rules apply, meaning you call and use data under domestic rates. Even so, providers retain the legal right to cap fair-use data volumes while roaming abroad without surcharges. The regulator Autoriteit Consument & Markt (ACM) monitors these requirements, and you can review their guidance on the ACM mobile subscription advice page.
Keeping your phone number and switching provider
You have the right to keep your existing phone number at zero cost when you switch mobile operators. This legal right is called nummerbehoud (number retention). Your old provider cannot refuse this request, and they cannot charge an administration fee for releasing your number. You remain entitled to transfer your number up to one month after your old agreement ends. Numbers can even be moved before your original term finishes, although you still owe the remaining contractual fees to your previous carrier.
The easiest way to switch without downtime is through the official switching service. Your new provider contacts your old provider directly, arranges the transfer date, and cancels the old line on your behalf. When moving to a contract with fewer numbers, you decide which ones carry over:
- You cancel a plan with two numbers and start a plan with one, keeping your preferred number.
- You cancel a family plan with four numbers and split them across two separate providers, assigning one number to the first and three to the second.
Fixed landline numbers can also be retained, but only as long as you stay within the same regional telephone area. Dutch geographic numbers begin with specific prefixes, such as 030 for Utrecht. If you move across regional boundaries, your landline prefix changes and you receive a new number. Mobile numbers have no geographic ties and move anywhere in the Netherlands.
Service disruptions during switching must not exceed one working day. You must be able to place calls no later than one day after the scheduled date. If a provider stalls your number transfer, file an official complaint in writing, as outlined on the ACM number retention page.
Home internet: which providers you can choose at your address
Fixed home internet availability in the Netherlands depends entirely on the physical network connected to your address. Unlike mobile connections that broadcast over the air, fixed line services enter buildings through copper wiring, coaxial cable, or optical fibre. No single company is forced to supply broadband everywhere, but the Ministry of Economic Affairs and Climate Policy ensures that basic internet remains generally accessible and affordable nationwide.
Every address has access to a specific cable infrastructure operated by local network owners. In any given postal code, you will encounter distinct technical options:
- Coaxial television cable operated by a single regional player like VodafoneZiggo, Delta, or Caiway.
- Traditional copper telephone pairs owned by KPN, delivering ADSL or VDSL broadband.
- Fibre optic lines installed by KPN, Glaspoort, Open Dutch Fiber (ODF), or regional operators.
- Wholesale third-party providers that lease space on open networks to sell competitive retail packages.
KPN holds a unique statutory obligation. By law, KPN must provide an affordable fixed telephone line to every household that asks for one. They satisfy this universal service duty with offerings like Belbasis or Belbudget, and they may deliver this over a mobile connection if no fixed line reaches your home. However, KPN is not obligated to bundle broadband internet with that mandatory phone service.
Network owners are generally not required to open their lines to competing internet companies, though KPN and Glaspoort do grant access. On the Open Dutch Fiber network, provider Odido frequently holds exclusive access during the first year after rollout, after which other retail brands can offer services. Check your postal code on comparison portals or via ACM guidance on selecting a telecom provider to identify the specific lines delivering internet to your doorstep.
Speed, fibre and your own modem
Fixed internet contracts must state three separate speed figures: minimum speed, normally available speed, and maximum speed. The measured download and upload rate in your home must never fall below the agreed minimum speed. Your connection must reach the normally available speed in at least eight out of ten speed tests. In at least one out of ten tests, your line must reach ninety percent of the stated maximum speed.
Copper networks are gradually disappearing across the country. Telephone lines made of copper struggle to sustain high data volumes over long distances, require high maintenance, and consume excessive electrical power. Telecom operators are replacing copper cables with glasvezel (fibre optic cable). You will see ground crews laying cables marked by distinct coloured outer jackets:
- Orange jackets belong to KPN.
- Green jackets belong to Delta.
- Turquoise jackets belong to Odido.
- Magenta jackets belong to Primevest.
Telecom operators switch off the old copper telephone line once fibre is installed in your neighbourhood. Landlords or homeowners can decline a fibre connection when the street is being excavated, but requesting an installation later creates a na-aansluiting (post-installation). Post-installations often trigger separate one-off charges or recurring monthly fees from the network manager.
To verify if you receive your contracted bandwidth, connect a modern laptop directly to your router with an Ethernet network cable rather than testing over Wi-Fi. Turn off all streaming devices, background downloads, and active applications before launching tests on independent speed test platforms. If tests consistently fall short of the numbers in your contract, notify your provider in writing with your logged data. When evaluating your broadband quality, review the official standards on the ACM internet speed information page.
Contract length, cancelling and price increases
A consumer telecom contract in the Netherlands can have an initial fixed term of at most two years. Locking customers in for longer than two years is not allowed. Once that initial fixed period expires, the provider cannot tie you into another fixed year automatically. Instead, the contract rolls over indefinitely (stilzwijgende verlenging), meaning you can cancel at any time by giving one month of notice.
Your provider must send you an annual summary of their best available rates. At least one month before your initial contract expires, the company must alert you that your commitment is ending. This message must state that you are free to cancel without costs and present you with their most favourable alternative deals. If you decide to sign a new discounted agreement, a fresh fixed term of one or two years starts.
You can cancel your subscription using the exact same channel you used to purchase it. If you concluded the contract online, the company must provide an online cancellation route, such as a web form or an email address. Always demand written proof of your cancellation to prevent billing disputes later.
If your provider alters contract terms or raises prices to your disadvantage, you have the right to cancel your plan immediately without penalty, even during an active fixed-term agreement. The provider must give you personal notice at least one full month before the change takes effect. This free cancellation right does not apply if the price rise matches the annual inflation percentage published by the Centraal Bureau voor de Statistiek (CBS), provided that this inflation clause is written into the general terms. For further rules on early termination, read the ACM contract cancellation guide.
Outages and complaints: your rights as a customer
You are entitled to statutory financial compensation whenever a phone or internet outage lasts longer than 12 hours. This rule applies if the failure sits within the provider's network or hardware and is not caused by your own domestic devices. Faulty customer-owned wiring, self-installed splitters, or third-party routers do not qualify for compensation.
The compensation rate depends directly on the downtime and your regular monthly subscription cost:
- Downtime between 12 and 24 hours entitles you to one full day of subscription fees.
- Outages lasting past 24 hours entitle you to one day of fees for every additional day the disruption touches, regardless of how many hours the problem persists on that second day.
- Prepaid mobile users receive a fixed 0.50 euro compensation for interruptions exceeding 12 hours, plus an additional 0.50 euro for each subsequent affected day, subject to a statutory minimum payout of 1.00 euro.
Calculate your daily subscription fee by dividing your gross monthly fee by 30. If you buy an alles-in-1 (all-in-one) package covering television, home broadband, and landline phone service, divide the combined bundle fee by 30 even if only one individual service fails. However, monthly repayment charges for a mobile phone handset cannot be included in this calculation.
Providers may offer compensation in mobile data vouchers or extra calling credits instead of cash, but you can insist on direct credit against your invoice. If customer service refuses your statutory compensation, submit a formal complaint letter setting a reasonable deadline for resolution, as outlined on the ACM telecom outage compensation page.
What the KNM exam asks about this
The Kennis van de Nederlandse Maatschappij (KNM) exam covers daily life and practical administration in the Netherlands, with contracts for your home falling under the theme Wonen. A question may ask how consumer contracts work, how long initial subscriptions run, or what rights you have when a service fails, often as a short story where a resident receives a higher monthly bill, moves house, or faces an unexpected contract renewal. Knowing the standard notice period of one month, the 14-day statutory cooling-off window, and how to file a complaint with the provider helps you answer.
