# Abonnement-goedkoop.nl

> Abonnement-goedkoop.nl compares Sim Only mobile plans and plans with a phone in the Netherlands, to help people find the cheapest plan that fits what they need. It lists 403 Sim Only plans from 11 providers and 10453 plans with one of 187 phones from 11 providers, last updated 2026-11-13. The site is in Dutch; prices are in euros per month, apart from what is paid upfront for a phone.

How prices are compared:

- By default every list is sorted and filtered by the price after the promotion: the monthly price once any introductory discount is over, which is what you pay for most of the contract. Cheapest first.
- Many plans have a lower promotional price for the first months of the contract (how many differs per offer). It is shown next to the price after the promotion, but only decides the order when you add `prijs=nu` to the URL ("price now"), which then lists only the plans that have a promotion.
- Plans at the same price are ordered by the other price, then always in the same order.
- A plan with a phone also has a one-off payment upfront for the phone (a connection fee included). Its monthly prices, and the price filters, are without it, but plans with a phone are sorted by what they cost a month on average over the contract, the upfront payment and any promotion included, so a deal with a lot to pay upfront is not first for its low monthly price.
- The order is by price only, never by commission.

Affiliate disclosure: the site is free to use. Its offer links ("Bekijk aanbieding") redirect to the provider, and the site may earn a commission when a plan is taken through one. It lists the plans from its providers' product feeds, so not every plan on the Dutch market is necessarily in it.

## Pages

- [All Sim Only plans](https://www.abonnement-goedkoop.nl/sim-only): every plan on its own, cheapest after the promotion first, 24 per page. By provider instead, add `weergave=providers`: https://www.abonnement-goedkoop.nl/sim-only?weergave=providers, each provider's cheapest plan with up to three of its others below it (with filters its next cheapest, without them the cheapest of each of its other data bundles), 24 providers per page; the rest of a provider's plans only load with a click. Both take the filter parameters below.
- [Phones with a plan](https://www.abonnement-goedkoop.nl/mobiele-telefoons): every phone that comes with a plan, those chosen most first, each with a page of its plans at https://www.abonnement-goedkoop.nl/abonnement-met-telefoon/{slug}, cheapest first. Search them with `q`, for example https://www.abonnement-goedkoop.nl/mobiele-telefoons?q=iphone.
- [All plans with a phone](https://www.abonnement-goedkoop.nl/abonnement-met-telefoon): every phone's plans, each on its own, cheapest first, 24 per page.
- [Providers](https://www.abonnement-goedkoop.nl/providers): every provider, each with a page about it at /providers/{slug} (its network, and links to its plans). For one provider's plans, use the `brand_id` filter below.

- [Plan finder](https://www.abonnement-goedkoop.nl/beste-mobiele-abonnement): advice on the three cheapest plans for what someone needs, each at another provider: Sim Only, or with a phone. Its answers go in the URL: for a phone with the plan `with_phone=1` and `phone` (the phone's slug, the end of its page's URL), `data` (1, 5, 10, 20, 40 or `unlimited`, in GB), `contract_months` (1, 12 or 24) and, for a perk at a provider they already have something with, `current_subscriptions[kpn][]=internet` (providers `kpn`, `vodafone`, `odido`; services `internet`, `tv`, `mobile`).

## Filtering plans by URL

Add these query string parameters to https://www.abonnement-goedkoop.nl/sim-only (or to a network's page, to the plans with a phone or a phone's page, or to the JSON API below). Every filter has to match.

- `price_min`, `price_max`: monthly price in euros, against the price after the promotion (or the promotional price with `prijs=nu`); for a plan with a phone, without its upfront payment.
- `upfront_min`, `upfront_max`: for a plan with a phone, what is paid upfront for the phone, in euros.
- `data_min`, `data_max`: data per month in GB. A plan with unlimited data matches any `data_min`, but never a `data_max`.
- `minutes_min`, `minutes_max`: call minutes per month. Unlimited calling matches any `minutes_min`, but never a `minutes_max`.
- `contract_duration`: contract length in months: 1 (cancel monthly), 12 or 24. Several with `contract_duration[]=12&contract_duration[]=24`.
- `network`: `kpn`, `vodafone` or `odido`: plans on that mobile network, from any provider.
- `brand_id`: a provider's id (see /llms-full.txt or `provider.id` in the JSON API). Several with `brand_id[]=1&brand_id[]=2`.
- `prijs`: `na-actie` (default, the price after the promotion, every plan) or `nu` (the promotional price; only plans with a promotion).
- `weergave`: `alle` (default, every plan on its own) or `providers` (by provider). Not for the JSON API, which always lists every plan on its own.
- `page`: the page of results: 24 plans each, or 24 providers with `weergave=providers`.

Examples:

- At least 10 GB for at most €15 a month: https://www.abonnement-goedkoop.nl/sim-only?data_min=10&price_max=15
- Cancel monthly, on the KPN network: https://www.abonnement-goedkoop.nl/sim-only?contract_duration=1&network=kpn
- The lowest promotional prices, with at least 20 GB and 500 minutes: https://www.abonnement-goedkoop.nl/sim-only?prijs=nu&data_min=20&minutes_min=500

Filter with `network` or `brand_id`.
- A phone's plans as JSON, at its `plans_api_url` (https://www.abonnement-goedkoop.nl/api/v1/phones/{slug}): the plans on that phone's page, cheapest first, with the same filter parameters as the Sim Only plans.

Sorted as the phone's page is, by `total_contract_cost` over `contract_months`. Also takes `upfront_min` and `upfront_max`.
