How much data do you really need?
According to BIPT, the Belgian telecom regulator, average mobile data use tripled in five years: from 3.9 GB to 11.9 GB a month in 2025. Bundles grew even faster. In 2025 nearly 8 in 10 residential customers with a subscription had more than 10 GB included, compared with 6 in 10 two years earlier.
Calling stayed stable, at around 155 minutes a month. Texting fell from 114 messages a month in 2020 to 46 in 2025.
An average says little about you. So look at your invoices from the last three months: your real usage is almost always lower than you think.
Who is a small plan good for?
You’re mostly on wifi. If you have wifi at home and at work, you rarely go above 2 to 3 GB. A 20 GB bundle is then money down the drain.
Your child’s first phone. A fixed price and a limited bundle, cancel any month. No surprises on the bill.
A second number or a spare phone. You use little, so only the monthly price counts.
You don’t call much. You want to be reachable, but you rarely make long calls. Then a small bundle is enough.
What to look for when comparing
UNDO isn’t always the cheapest. There are smaller plans in Belgium under €4, and promotions sometimes lower the price temporarily. So look beyond the price in the ad:
Introductory price or fixed price? Comparison sites often rank by the first-year price. Compare what you pay from month 13.
What happens to what you don’t use? With many operators unused data expires at the end of the month. Over a year, that adds up.
What does an extra GB cost? Some operators charge several times their normal price as soon as you go over your bundle.
Compare based on your own usage? You can with BIPT’s rate simulator at bestetarief.be.
What if 4 GB isn’t enough?
If you occasionally go over your bundle, you pay €1 per extra GB. If you regularly need more, switch to a bigger plan:
All plans can be cancelled any month, so you’re never stuck with the wrong choice. With every plan you support certified climate projects with CO₂ credits.
Any questions? Read what happens to what you don’t use, what happens when your data runs out and how to set a limit.
