Top 8 best 5G plans in Belgium

The best 5G plan in Belgium right now is DIGI 60 GB at €9 a month: 60 GB, unlimited calls and texts, and a price the operator has committed not to raise during 2026. For the same budget, Mega Spark gives 30 GB with no time-limited promotion at all. At the other end, Proximus Mobile Smart charges €24.99 for 60 GB — roughly three times DIGI's price for a comparable allowance, and what that buys is one thing only: the best 5G coverage in the country, measured by the BIPT at around 65 % of the territory outdoors. That is the Belgian market in a sentence: three networks, about fifteen labels, and a price gap that comes almost entirely from the brand printed on the SIM. This ranking compares the eight 5G plans that hold up in July 2026, on the price actually paid once the promotion ends, the data really included, and the host network — because a Mobile Vikings plan and an Orange plan run through the same masts.
