Top 8 best 5G plans 2026
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.
Updated 17 July 2026
What is the best 5G plan in Belgium in 2026?
DIGI 60 GB, at €9 a month. It gives 60 GB of 5G data, unlimited calls and texts, and DIGI confirmed in January 2026 that it would not raise any of its fixed or mobile prices this year — a rare commitment in a market where annual indexation is the norm. No other Belgian operator goes below €10 with this much data and a price that holds.
The caveat is real and worth stating: DIGI is still building its network. The operator reported roughly 30 % of the population covered by its own antennas at the end of 2025, targeting near-national coverage by 2030; the rest of the time your phone falls back on national roaming. If you live and work in an already-covered urban area, this is an excellent deal. If you drive 80 km a day through the countryside, test before you cancel your current line.
If a network under construction worries you, Mega Spark at €9 for 30 GB is the obvious runner-up: half the data, but the Orange network behind it and no promotion that expires.
Which operators actually own a 5G network in Belgium?
Three: Proximus, Orange and Telenet. Every other brand you meet in a comparison rents one of them — that is what an MVNO is. DIGI is the fourth case, apart: it is deploying its own masts, but only partially.
The split, as of July 2026: Scarlet and Lycamobile run on Proximus. Mobile Vikings, hey! Telecom, Mega, yoin, edpnet, JIM Mobile, Neibo, UNDO and VOO run on Orange. BASE, Mixtus and TADAAM run on Telenet. This detail changes everything: a hey! Telecom plan at €14 for 50 GB and an Orange plan at €23 for 70 GB use exactly the same masts with exactly the same 5G coverage. The €9 gap does not buy signal; it buys a shop, a call centre and a brand.
That is also why a 5G ranking that does not print the host network next to each price is useless. Here, every row carries it.
How much does a 5G plan cost in Belgium, and why do headline prices lie?
An honest 5G plan costs between €9 and €25 a month depending on data. Below that, you are almost always inside a twelve-month promotion, and the advertised price is not what you will pay.
The figures surveyed on 17 July 2026 speak for themselves. Mega Glow advertises €1 a month for 5 GB: true for twelve months, then €4. yoin offers 150 GB at €4 a month; in month thirteen the bill becomes €25, a six-fold increase. Mega Flash shows €9 for 60 GB, then €14. None of these offers is dishonest in itself — the terms are written down — but a ranking that sorts them by headline price mechanically puts promotions on top and lies about the real cost.
Our rule is simple: we rank on the month-thirteen price. On that basis, DIGI 60 GB at €9 and Mega Spark 30 GB at €9 stay at €9 indefinitely, while the €4 yoin becomes one of the most expensive plans in the table. Over 24 months it is starker still: €216 with DIGI against €348 with yoin (12 × €4 + 12 × €25).
Is 5G really worth it, or is 4G enough?
For email, scrolling and HD video, 4G is plenty — and 4G coverage is better everywhere. 5G becomes useful for 4K streaming, cloud gaming, tethering a laptop, or in congested places: a station, a stadium, central Brussels at 6 pm. The difference is less raw speed than the ability to absorb thousands of devices in one spot.
The BIPT's measured speeds put things in perspective. Proximus network: up to 136.8 Mbps, around 65 % outdoor coverage and 35 % indoors. Telenet network: up to 90.7 Mbps, ~62 % outdoors, ~29 % indoors. Orange network: up to 94.5 Mbps, ~52 % outdoors, ~31 % indoors. That is a long way from the gigabits of the launch presentations, and the indoor/outdoor gap explains why 5G often vanishes the moment you get home.
Two conditions before paying for 5G: a compatible handset (otherwise the plan drops to 4G and you pay for nothing), and real coverage at your address. Check it on the operator's site, not on a marketing map.
How do you switch 5G plan without getting caught out?
Since July 2022, Belgian law lets you cancel a mobile plan free of charge after six months, keeping your number. It is the most under-used lever on the market: nothing stops you trying DIGI or an MVNO for six months and leaving if coverage disappoints.
Three habits, in order. Check coverage at your address and along your daily routes — not just at the office. Look at the data allowance rather than the 5G label: 5G burns through data faster, and 5 GB disappears over a weekend if you stream. Finally, compare the MVNOs on the same network as the operator you like: hey!, Mobile Vikings and Scarlet resell Orange's or Proximus's signal, often at half the price.
One last point: number porting goes through Easy Switch, and the new operator handles the cancellation. You do not have to call the old one and be talked into a retention offer.
Comparison table
Methodology : Surveyed 17 July 2026, postcode 1000 (Brussels). Prices and allowances come from the operators' public price lists and from the Selectra/CallMePower telecom comparison engine, which pulls them live from the catalogues. 5G coverage and speed figures are the BIPT's, network by network. Ranking is done on the MONTH-THIRTEEN PRICE: a promotional offer is judged on its post-promotion rate, never on its headline price. The score out of 100 weights data per euro (40 %), the host network's real BIPT coverage (25 %), included calls and texts (15 %) and price stability over time (20 %). No plan was field-tested by the editorial team: this ranking compares price lists and public measurements, not impressions of use. No link in this ranking is monetised — links point to the brand's official site.

Frequently asked questions
What is the cheapest 5G plan in Belgium?
Excluding promotions, DIGI 7 GB at €3/month is the lowest entry ticket on the market, unlimited calls and texts included. If you want the best data-per-euro rather than the lowest absolute price, DIGI 60 GB at €9/month and Mega Spark 30 GB at €9/month are ahead. Offers advertised at €1 or €4 (Mega Glow, yoin 150 GB) are twelve-month promotions that then rise to €4 and €25.
Which operator has the best 5G coverage in Belgium?
Proximus. According to BIPT measurements its network reaches up to 136.8 Mbps with around 65 % outdoor and 35 % indoor coverage — the most advanced rollout in the country (Antwerp, Ghent, the coast, several areas of Brussels, Bruges, Leuven, Kortrijk and Ronse). Telenet follows with ~62 % outdoors and up to 90.7 Mbps, Orange with ~52 % outdoors and up to 94.5 Mbps.
Do Mobile Vikings and Scarlet give the same 5G as the big operators?
Yes, give or take their host's coverage. Scarlet runs on the Proximus network; Mobile Vikings and hey! Telecom run on Orange. Coverage and speeds are the host network's: only price, customer service and options differ. That is what makes a hey! Telecom 50 GB plan at €14 directly comparable to an Orange Mobile Medium 70 GB at €23.
How much data do you really need with 5G?
Between 20 and 30 GB for ordinary use (social media, music, browsing, some video). Count on 50 to 60 GB if you watch series on the move or tether. Unlimited (Mobile Vikings Unlimited Basic at €25, TADAAM at €25) only makes sense if your phone replaces a fixed line. 5G shifts the maths: with identical habits you consume faster, because everything loads faster.
Do you need a special smartphone for 5G?
Yes. Without a 5G-capable handset the plan automatically falls back to 4G and you pay extra for nothing. Most models sold since roughly 2021 are compatible, but check the spec sheet before subscribing — and check that your device's 5G bands match those used in Belgium if you bought it outside the EU.
Can you cancel a 5G plan without a fee?
Yes, after six months, since July 2022. Belgian law bans cancellation fees beyond that point, and Easy Switch lets you keep your number: the new operator handles the switch. In practice, trying DIGI or an MVNO commits you for six months only.
Is DIGI worth it despite its incomplete network?
In urban areas, yes: 60 GB at €9 with a price frozen until the end of 2026, and no competitor comes close. In rural areas or on long daily commutes, be careful — DIGI reported around 30 % of the population covered by its own antennas at the end of 2025, with national roaming filling the gaps. The general rule applies here more than anywhere: check coverage at your address before signing, and use the six-month free cancellation window as a trial.
