hey! Telecom: the most readable 5G plan range in Belgium?

Four lines. That is the entire hey! mobile catalogue, and it already says something in a Belgian market where yoin lists nine price lines and Neibo just as many, where Scarlet asks you to arbitrate between Red, Berry, Cherry and Hot, and where Mega offers Glow, Spark, Star and Flash without any of those names telling you how many gigabytes you are buying.

At hey!, the four plans are called S, M, L and XL. One axis: data volume. Everything else — unlimited calls, unlimited texts, no commitment, the Orange network — is identical across the range. The question is whether that readability holds up on the bill, and what it costs elsewhere.

What exactly is in the hey! range in August 2026?

Four commitment-free plans, from 15 to 160 GB, all on Orange's 4G/5G network. Here is the grid recorded on heytelecom.be on 2 August 2026, promotional discounts included.

All four include unlimited calls and SMS/MMS. None commits you: hey! is a fully online operator, launched on 24 September 2021 as Orange Belgium's digital brand, and cancellation happens from the customer area.

Two details matter more than average. Changing plan is free once a month, with prorated billing — so you can start on L and drop to M after a month of real usage, which no store-based operator makes this easy. And the subscription can be suspended for three months, useful for a long stay outside the EU.

What does hey! cost once the promotion is over?

Between €5 and €25, and it is the right-hand column of the table that matters. The €7, €11 and €21 rates include a discount of €2, €3 or €4 per month, along with extra gigabytes — 10 GB on the M, 30 GB on the L. hey! presents that discount as held "for life", meaning maintained for as long as the mobile subscription stays active.

Two conditions narrow the scope of that wording. The discount only applies to new subscriptions, and the order window runs from 4 June to 9 August 2026. After that date the M returns to €9, the L to €14 and the XL to €25, with the base volumes: 25 GB, 50 GB and 160 GB.

The out-of-bundle rate deserves a check on your side. The grid published by hey! states €0.001/MB in Belgium and in the EU, roughly €1 per gigabyte. Several Belgian comparison sheets still show €0.01/MB, ten times more. The mechanism itself is consistent: SMS alert at 80% then at 100% of the included volume, continuation out of bundle up to a €50 cap in Belgium and €60 in EU roaming, cut-off beyond that. Read the figure in your own terms before you go over, not in a third-hand table.

Are four plans really more readable than the rest?

Yes, and the gap is measurable. On a Belgian comparison site's 22 July 2026 snapshot, yoin lists nine price lines, Neibo nine, UNDO seven, Mega five, Scarlet five, Lycamobile five. hey! lists four, named after clothing sizes and separated by a single number.

That restraint has a practical consequence: it makes cross-operator comparison possible. When a catalogue crosses three data tiers, two calling levels and an "unlimited" option, you are no longer comparing prices, you are comparing combinations — which is exactly what stacking references produces, deliberately or not. A €12.50 plan for "30 GB + unlimited national" does not sit easily next to an €11 plan for 80 GB.

What is the network behind the hey! label worth?

Exactly what Orange is worth, bit for bit. hey! owns no masts: the brand resells access to Orange Belgium's 4G/5G network, of which it is the digital arm. Your coverage is Orange's coverage, at your address, with no discount and no bonus.

What the BIPT says about that network, in measurements rather than marketing maps: an average download speed of 94.5 Mbps and 24.4 Mbps upload. Proximus stays ahead at 136.8 Mbps, Telenet follows at 90.7 Mbps. On outdoor 5G coverage, the BIPT mobile atlas relayed in May 2026 puts all three networks at the top — 100% for Proximus and Telenet, 99.9% for Orange. Indoors the story changes: the BIPT measures a "very good" 5G signal at around 32% for Orange, far below the outdoor figure. A comparison sheet consulted in late July 2026 still quoted 62.70% 5G coverage for Orange: the data moved, the sheet did not.

Remember the mechanism rather than the percentage: Belgian 5G leans on the 3.6 GHz band, which travels poorly through brick and concrete. A hey! plan loses nothing when 5G stops at your front door — it falls back to 4G, like every other plan. Our comparison of the three Belgian networks has the network-by-network detail.

hey! or Orange: what is the price gap on the same masts?

Roughly double, and the gap widened in 2026. Since the tariff revision of 18 January 2026, the Orange grid puts Mobile Small at €14 for 8 GB, Mobile Medium at €21 for 50 GB and Mobile Unlimited at €39 for 300 GB.

The hey! S gives nearly twice the data for a little over a third of the Orange Mobile Small price. The L gives 30 GB more than Mobile Medium for half the rate. On the same masts, with the same coverage, in the same city.

What that €10 monthly gap buys at Orange is real, but it should be named: physical stores, phone support, internet + mobile bundles with coupled discounts, and multi-SIM reductions. If you use none of the four, you are paying for a commercial infrastructure, not for signal. The comparison also holds against the other brands hosted by Orange — Mobile Vikings and its €25 unlimited plan runs on the same network, with a different positioning.

Where does hey!'s readability stop?

At customer service and at bundles. hey! is fully online: support runs through the customer area chat, open from 8 a.m. to 10 p.m., and only blocking a lost or stolen SIM has a free phone number. No stores, no commercial phone line. Public ratings reflect that — 3.4/5 on Trustpilot across nearly 2,900 reviews, 3.5/5 on Google — with neither collapse nor enthusiasm.

The second blind spot is the bundle. hey! sells a mobile plan and an internet plan, never the two together. hey! internet is €29/month on promotion against €39 otherwise, carried over the Telenet and VOO cable networks in Wallonia and Brussels, at 200 Mbps down and 10 Mbps up, with no fibre. A household that wants a coupled mobile + internet rate has to look elsewhere.

One point in the brand's favour: Test Achats awarded it two "Best of the Test" labels in 2026, a distinction relayed by Orange Belgium and by hey! itself. We have not tested these plans in the field — we compare published price grids and public measurements, and we say so.

Should you take hey!?

If your address is well covered by Orange and you manage your subscription online, yes — the data-to-price ratio is among the most aggressive in Belgium, and the range reads in thirty seconds. The hey! mobile L at €11 for 80 GB is hard to beat on that network.

If you want someone on the phone, a store to walk into with a problem, or a bundle that couples your internet and your mobile, hey! is not your operator, and the monthly saving will not offset the frustration.

Either way, two steps before signing. Check Orange coverage at your exact address and along your commute, not at the scale of your municipality. And subscribe before 9 August 2026 if you are aiming at the M, the L or the XL, otherwise the "for life" discount will not apply. To place hey! against the other Belgian brands, thirteenth-month price in hand, our 5G plan ranking lines them up in the same column, and the comparison tool puts them side by side criterion by criterion.
