Don’t pay for gigabytes you never use

Test-Aankoop compared the cheapest mobile plans on the market right now. Their key piece of advice sounds very familiar to UNDO: don’t buy more data than you really need.

In its latest edition, Test-Aankoop lined up the most affordable mobile plans, neatly split by user profile — from people who barely browse to those who stream non-stop. The common thread? One simple piece of advice you probably saw coming: don’t pay for gigabytes you never use.

That’s exactly why UNDO exists.

“Buy less” is the best money-saving advice

The consumer organisation recommends checking your most recent bills and knowing your actual data usage before choosing a plan. If you use 10 GB a month, there’s no reason to pay for 50 GB. Sounds logical — and yet that’s exactly what a lot of Belgians do.

At UNDO, we flip that logic around. Instead of selling you as much data as possible, we help you choose what you really need. And whatever you don’t use stays yours: unused data, minutes and texts simply roll over to the next month.

Most people use less than they think

Test-Aankoop makes it concrete. Three hours a day on social media? That adds up to roughly 9 GB per month. Four hours of YouTube a month? About 4.7 GB. Even a heavy Spotify listener stays well below the dozens of gigabytes the big operators try to talk you into.

In other words: for a lot of people, a small, smart plan is more than enough. And that’s exactly where UNDO comes in.

UNDO Zero Waste: listed among the most affordable

For light data users, Test-Aankoop includes UNDO Zero Waste in its comparison of the cheapest plans. A telling detail: for that profile, Proximus and Orange don’t even make the top 10 of cheapest operators.

From €4 per month, UNDO Zero Waste gives you 4 GB of data, 400 minutes and 400 texts on the Orange 5G network — more than enough if you use your data mindfully. Need a bit more after all? Then you switch to a bigger plan effortlessly, no hassle.

Affordable and climate-neutral — no contradiction there

This is where UNDO makes the difference. Because with us, you don’t just pay less — you also call climate-neutral.

Every UNDO subscription offsets the CO₂ of your mobile usage and plants a tree: 1 subscription = 1 tree. With the UNDO Tracker, you can also see in real time what your mobile usage costs in CO₂. Just like Test-Aankoop advises you to track your data usage, we help you track your impact.

Mindful usage doesn’t just save on your bill. It saves the planet a little, too.

Work out what you really need

Test-Aankoop’s advice and UNDO’s philosophy boil down to the same thing: stop paying for what you don’t use. Check your usage, choose mindfully, and give the rest back to nature.
