Our verdict

DELTA Fiber suits Dutch households that want the home line and a sim-only mobile plan from the same provider. Plan for renewal fees of €42.50 to €125 rather than the entry rate, and expect full fibre to reach 8,000 Mbps on the largest plan.

Pros and cons

Pros

  • The highest tier reaches 8,000 Mbps with uploads of 100 to 8,000 Mbps, so large files and photo backups move without waiting.
  • The mobile side runs as an MVNO on the Odido network, with sim-only plans, wifi calling and hotspot sharing included.
  • Plan terms run 12 and 24 months, so a shorter commitment is available alongside a longer one.
  • Support runs on chat, phone and help centre, so a phone call or a live chat covers most questions before a help centre is needed.

Cons

  • Annual indexation can raise the monthly fee during and after a discount period, so renewal fees of €42.50 to €125 are the figure to plan around.
  • A setup fee of €29 is charged to join, above the €0 median across the site, so the opening bill is heavier than the monthly rate suggests.
  • Coverage is NL only, so the choice narrows for anyone who moves or splits a household across another border.

Who it suits

  • Households in NL that want home internet and a mobile line from the same provider.
  • People who send large files or back up photos, with uploads of 100 to 8,000 Mbps on the higher tiers.
  • Families adding lines, since a multi line discount is offered alongside sim-only plans and an unlimited plan at €25.

Who should look elsewhere

  • Homes outside NL: EarthLink lists fttp, 5G and satellite, so it covers connection types DELTA Fiber does not sell.
  • Households chasing the highest end of the speed table, since DELTA Fiber ranks 10 of 114 on max download while EarthLink lists a broader spread of technologies.

Core features

Lines run on fttp and cable, so a fibre plan and a cable plan sit in the same range. The highest tier reaches 8,000 Mbps with uploads of 100 to 8,000 Mbps, which matters for backups, cloud photos and sending large files out. The network reaches 1,700,000 premises, and the address checker settles whether a line serves a street before an order goes in. The box is a WiFi modem with WiFi 7 mesh points, so the mesh points arrive as part of the kit rather than as an add-on.

Plans and prices

Entry price is €30 a month. The reference plans list a lower speed tier, a gigabit tier and an Unlimited tier; the gigabit plan carries the entry rate, while the Unlimited plan sits several times higher. Set-up is charged at €29. Introductory pricing and renewal pricing are different numbers: once the discount period is over, fees run €42.50 to €125, and annual indexation can lift them during or after that period. The lower end of the renewal range is the closer guide to a steady monthly bill.

How it compares on our data

On max download, DELTA Fiber sits 10 of 114 brands, a high ceiling for the field. On post contract price the rank is 18 of 36, the stronger of the two cost measures. Entry price sits at 70 of 95 and the setup fee at 66 of 86, so the entry point is where it gives ground. The overall picture is a well ranked speed offering paired with a mid field entry price.

The company behind it

The business behind the mobile lines is DELTA Mobiel B.V., based in the Netherlands, so the company sits in the same market as the homes it connects. Support runs on chat, phone and help centre, meaning a phone call or a live chat handles most questions and a help centre covers the rest. A Dutch customer can raise a broadband or mobile problem through the same desk, which is convenient when both services arrive together.

Frequently asked questions

What does DELTA Fiber cost at the start?+

Entry price is €30 a month, and joining costs €29. The reference plans list a lower speed tier, a gigabit tier and an Unlimited tier, and the gigabit plan carries the entry rate while the Unlimited plan sits several times higher. The headline figure is introductory, so renewal fees of €42.50 to €125 are what to budget for later.

What happens to the price after the introductory period?+

Renewal fees run €42.50 to €125 after the discount period ends, and annual indexation can lift the monthly fee during and after that period as well. That is the figure to plan around rather than the entry rate, and it is what sets the standing monthly cost of the line.

Is there a setup fee?+

Set-up is charged at €29 on a new line, above the €0 median across the site. It is a joining cost rather than a monthly addition, so it lands on the opening bill and stays out of the plan price itself.

How fast is the connection, and what about uploads?+

The highest fibre tier reaches 8,000 Mbps, with uploads of 100 to 8,000 Mbps across the range. Lines run on fttp and cable, so a cable address will see a lower tier than a fibre one. Upload speed is the part that shows on backups, cloud sync and video calls.

Where does DELTA Fiber actually operate?+

Broadband runs in the Netherlands, so DELTA Fiber is a Dutch choice. The network reaches 1,700,000 premises, and the address checker confirms whether a line serves your building before you order. Mobile from the same provider is sold on the Odido network.

Can I get a mobile line with the broadband?+

Mobile is sold as an MVNO (mvno) on the Odido network, with sim-only plans, an unlimited plan at €25 and a multi line discount for extra lines. Wifi calling and hotspot sharing are included, and billing runs on a contract (contract).

How long is the contract, and how do I reach support?+

Plan terms run 12 and 24 months, so there is a shorter commitment as well as a longer one. Support runs on chat, phone and help centre, covering a phone call, a live chat and a help centre from inside the same market as the network.

What is the deal for roaming abroad?+

Roaming in the EU is fair use, so heavy data use abroad follows that allowance rather than unrestricted access. Worth reading the terms before a long trip, since the mobile side is built as a home market service rather than a travel one.
