What’s changing at Telenet

  • No more fixed bundles. Since 27 April 2026, ONE and ONEup are being phased out. You choose internet, mobile and TV yourself, and so put together your own package.

  • Entry-level internet €20 more expensive. The cheapest internet plan went from €36 to €56 a month, according to Test-Achats. The old Easy Internet with 150 GB has gone, the new basic plan has unlimited volume.

  • An investigation by the minister. Consumer Protection Minister Rob Beenders launched an investigation into the new rates.

  • Watch out for welcome discounts. Part of the new prices is a discount that only lasts a year. If you still have a ONE or ONEup bundle, Test-Achats advises not to switch to the new offer without thinking it through.

Why it pays to look at mobile separately

In a bundle it’s hard to see what each part costs. The discount makes the whole cheaper, but your mobile plan often comes with more data than you use. Now that the fixed bundle is going, you can see what you pay per service.

According to BIPT, the average Belgian used 11.9 GB of mobile data a month in 2025. If you have wifi at home and at work, you’re often well below that. An unlimited bundle is then money you leave on the table every month. Also read which plan suits 2 to 5 GB.

How to go about it

  1. Check your last three invoices for how much data, minutes and texts you really use.

  2. Compare internet and mobile separately, on bestetarief.be from BIPT or at Test-Achats.

  3. Calculate with the price after a welcome discount, not the first-year price. Here’s how to work out what a plan costs over two years.

  4. Switching? Keep your number. Your new operator handles the switch and cancels your old subscription. With an eSIM it’s quick.

When a combination is still better value

If you watch TV through your operator and there are several phones in your household, having everything with one operator can still pay off. Do the maths, with the prices after the first twelve months.

Mobile at UNDO

UNDO only does mobile, on Orange’s 5G network. You combine it with internet from any operator.

  • Zero Waste: 4 GB of data, 400 minutes and 400 texts for €4 a month

  • Rise: 8 GB of data, 800 minutes and 800 texts for €8 a month

  • Boost: 30 GB of data, unlimited calls and 100 texts for €18 a month

  • Wild: 40 GB of data, unlimited calls and texts for €24 a month

Every plan can be cancelled any month and what you don’t use carries over to the next month. For every new subscription we plant a tree, and with every plan you support certified climate projects with CO₂ credits.
