Read more All UNDO contact detailsAbout this provider
UNDO is a climate-positive Belgian telecom provider. The surplus from every subscription is invested in projects that pull CO₂ out of the atmosphere — turning your monthly mobile bill into climate-positive impact rather than passive emissions.
For its mobile plans, UNDO uses the network of Orange in Belgium, with the same 4G and 5G coverage as Orange customers. UNDO does not offer fixed broadband or TV — the focus is purely on mobile.
UNDO network and coverage
UNDO uses the Orange Belgium mobile network for all its mobile plans. 4G and 5G coverage is therefore identical to Orange. UNDO does not offer fixed broadband or TV.
Prices in July 2026 excluding additional fees — only promotions from our partners are included.
