Belgians are using more data than ever

It's not your imagination - data consumption in Belgium has more than tripled in five years, from an average of 3GB per month in 2019 to over 10GB per month today, according to Belgium's telecom regulator BIPT. Streaming, video calls, and social media are the biggest drivers.

If you're staying connected with family abroad through daily video calls, streaming shows from home, or are a content creator, your real usage is often higher than you'd guess.
