How an introductory price works

Most Belgian mobile plans start with a discount for a limited time. After that you pay the standard price. It’s in the terms, so it’s allowed. But the price you see when you sign up isn’t always the price you pay a year later.

Comparison sites sort by today’s price. Plans with a temporary discount therefore often rank above plans with a lower fixed price.

Work it out over two years

An example with rounded amounts:

  • Plan A: €10 a month in the first year, then €20. After twelve months you’ve paid €120, after twenty-four months €360.

  • Plan B: €4 a month, with no end date. After twelve months you’ve paid €48, after twenty-four months €96.

In the first year the difference seems small. In the second year it adds up. So compare what you pay over two years, not just today’s monthly price.

What to look for in the terms

  • How long the introductory price runs: six months, twelve months or not at all

  • Which standard price follows

  • Whether the price also applies to existing customers, or only to new ones

  • Whether unused data expires at the end of the month

  • What an extra GB costs if you go over your bundle

  • How long your notice period is

When a promotion is better value

If you switch operator every year, you can save with introductory prices. Keeping your number is free in Belgium, so switching is easier than it sounds. If you stay on the same plan for years, a fixed price is usually better value.

Zero Waste: one price since June 2025

Zero Waste launched in June 2025 at €4 a month, and still costs €4 today. There’s no introductory price, and new and existing customers pay the same.

  • 4 GB of data, 400 minutes and 400 texts, on Orange’s 5G network

  • What you don’t use carries over to the next month

  • €1 per extra GB if you need a bit more

  • Cancel any month, and your number comes with you for free

  • A tree at activation in our own forest in Congo, and CO₂ credits for certified climate projects

Need more? Rise (8 GB, €8), Boost (30 GB, €18) and Wild (40 GB, €24) work the same way: one price, with no introductory discount.
