Proximus, Orange or Telenet: which 5G network works best in Belgium?

Three 5G networks. That is all Belgium has, and it is the first figure to hold in mind before comparing anything. Proximus, Orange and Telenet own masts; every other name you meet in a comparison — Scarlet, Mobile Vikings, hey!, Mega, BASE, yoin, Neibo, VOO — rents one of the three. DIGI is the recent exception, building its own network, still partial.

In other words: choosing a 5G plan means making two separate choices. A network, which decides what you receive. A brand, which decides what you pay. The two have nothing to do with each other, and confusing them is the most common mistake on the Belgian market.

Which 5G network works best in Belgium?

Proximus, no argument. BIPT measurements put it ahead on all three metrics that matter: around 65 % outdoor coverage, around 35 % indoors, and speeds up to 136.8 Mbps. It also holds the widest 5G spectrum in the country and the most advanced rollout — Antwerp, Ghent, the coast, several areas of Brussels, Bruges, Leuven, Kortrijk and Ronse.

Telenet sits just behind on outdoor coverage at ~62 %, but tops out at 90.7 Mbps. Its network is live in Antwerp, Genk, Ghent, Hasselt, Leuven, Kortrijk, Roeselare and along the coast, gradually moving to 5G standalone. Indoors it is the weakest of the three: ~29 %.

Orange comes last on outdoor coverage (~52 %) while offering slightly more speed than Telenet (94.5 Mbps). Its network covers Antwerp, Bruges, Ghent, Leuven and several points along the coast, expanding steadily into the larger cities.

What are Belgian 5G speeds actually worth?

A lot less than you were promised in 2020. The gigabits of the launch presentations reflected laboratory conditions: a mast thirty metres away, one device connected, clear skies. In real life, the BIPT measures 136.8 Mbps at best.

That is not bad news in itself — 136 Mbps covers just about everything you do with a phone, 4K included. But it puts the sales pitch in perspective. 5G's real contribution is not raw speed: it is capacity. Where 4G chokes when fifteen thousand people leave a stadium at once, 5G absorbs it. You feel the difference at Brussels-Midi at 6 pm, not running a speed test in your garden.

Why does 5G disappear when you get home?

Because coverage maps advertise the outdoors, and physics handles the rest. Look at the gap: Proximus falls from ~65 % to ~35 % the moment you cross a doorway. Telenet, from ~62 % to ~29 %. Orange, from ~52 % to ~31 %.

The reason is technical and stubborn. Belgian 5G leans heavily on the 3.6 GHz band, which carries poorly and penetrates worse. A solid brick wall, high-performance double glazing, a concrete-framed building: each eats part of the signal. 4G's lower frequencies travel far better — which is exactly why your phone switches itself back to 4G in the living room.

Which brand runs on which network?

The split, as of July 2026, fits in three lines. Proximus network: Proximus, Scarlet, Lycamobile. Orange network: Orange, Mobile Vikings, hey! Telecom, Mega, yoin, edpnet, JIM Mobile, Neibo, UNDO, VOO. Telenet network: Telenet, BASE, Mixtus, TADAAM.

That table is worth money, literally. A hey! Telecom 50 GB plan costs €14 a month and runs on Orange's masts. An Orange Mobile Medium 70 GB costs €23 and runs on the same masts. For €9 more you are not buying a better signal — you are buying 20 GB, a shop and a call centre. Whether that is worth it is your call.

Should you pick the network or the price?

The network first, the price second — never the other way round. A €9 plan on a network that does not reach your home is €9 wasted. Once the network is settled, though, let price decide without sentiment: on a single network, the gap between the operator and its cheapest MVNO is often two to one.

DIGI deserves a separate mention. The operator breaks the market on price — 60 GB at €9 a month, with the rate frozen until the end of 2026 — but its own network covered only around 30 % of the population at the end of 2025, with national roaming filling the gaps. In town, it is an excellent deal. Across 80 km of daily countryside, test before you cancel.

How do you check what your address receives?

Three steps, in order, none taking more than five minutes.

First, the operator's coverage map, at your exact address — not your municipality's. Then the same check along your routes: home is irrelevant if you spend your days elsewhere, and 5G on a train has nothing to do with 5G in a living room. Finally, use Belgian law: since July 2022 cancellation is free after six months, number kept via Easy Switch, and the new operator handles the switch. Six months of subscription is the only coverage test that does not lie.

One last check, obvious but common: your handset must support 5G. Otherwise the plan falls back to 4G permanently and you pay a premium for a technology your device cannot receive.

So what do you actually take?

It depends on what your address receives — which is exactly why nobody can answer for you in one line. What we can do is line the real prices up against each network: our 5G plans ranking compares the eight offers that hold up on the month-thirteen price, not the headline price. And if you want to weigh them criterion by criterion, the comparison table puts all eight side by side.
