MVNO or budget brand: the difference in Belgium

An MVNO is a mobile operator that rents someone else's network without owning a single mast. In Belgium, a good half of the brands filed under that label are not MVNOs at all: hey!, Scarlet, VOO, BASE and Mobile Vikings belong to the group whose network they use. Sorted as of 29 September 2026, host network shown.

What is an MVNO, exactly?

MVNO stands for mobile virtual network operator. It has no mast, no spectrum bought at auction and no mandatory core network: it buys wholesale capacity from an operator that has them, then resells plans under its own name at its own prices.

The word covers two trades with almost nothing in common. A full MVNO rents the radio layer but runs its own core network, issues its own SIM cards and handles its own calling features. A light MVNO simply resells, with the card, the voice platform and most settings remaining the host's. In between, an MVNE (mobile virtual network enabler) can rent its technical platform to brands that do not want to build one. None of these three profiles is an operator's budget brand.

The budget brand is not a tenant. It is the owner's second shop window.

Seven Belgian "MVNOs" belong to network operators

The MVNO list of a major Belgian comparison site, shown as updated on 29 September 2026, files Scarlet, Mobile Vikings, hey!, VOO, TADAAM and even DIGI, which owns its masts, under that name. The same page still places edpnet on the Orange network, although the brand moved to DIGI in February 2026, and shows former Mega plan names at 1 €, a teaser price with no promotion length.

Sorted from the official pages of the groups and brands, the picture looks like this.

Seven brands out of fourteen therefore belong to one of the three incumbent groups. The true independent MVNOs number five: yoin, UNDO, Neibo, Mega and Lycamobile, plus a few niche labels on the Telenet/BASE network such as United Telecom and Ello Mobile.

Why does an Orange customer moving to hey! keep the same SIM card?

Because the card belongs to the core network, and hey! has no core other than Orange's.

hey!'s plans page, consulted on 29 September 2026, says it plainly. A number arriving from Proximus, VOO, Telenet or BASE gets a new card. A number arriving from Orange keeps its own. No MVNO, even a light one, can offer that: its card is either its own or its host's, never that of a rival that happens to own the masts.

Belgian history provides the counter-test both ways. At the end of 2015, Telenet sold mobile as a full MVNO on the Mobistar network, today's Orange, to about 900,000 subscribers; after the BASE takeover, cleared in February 2016, those customers were moved onto BASE masts without changing SIM card, precisely because Telenet already ran its own core. Conversely, Mobile Vikings customers received a new card in February 2022 when moving from the Orange network to the Proximus network.

The SIM card tells you who owns the core. The logo printed on it only tells you who bills you.

The cheapest gigabyte comes from the operator, not the tenant

Here is the thesis, and it runs against intuition. On the Orange network, the owner's entry brand sells a gigabyte three to five times cheaper than the independent MVNOs renting the same masts.

Prices surveyed on 29 September 2026, except Mega (10 September 2026). No temporary discount is included: hey! mobile S, Orange Mobile Small and UNDO showed none, and the others were surveyed at the standard rate.

Two gaps stand out. The first sets the owner against its tenants: 0.33 € versus 1 € to 1.60 € per gigabyte, with UNDO keeping an edge only in absolute terms, at 4 € for a third of the allowance. The second plays out inside a single group, on a single network, for a single 15 GB allowance: 5 € at hey!, 18 € at VOO, which is 13 € a month and 156 € a year between two brands answering to the same shareholder.

The explanation lies in the cost structure. An MVNO pays its host a wholesale price that includes the host's margin. An entry brand pays itself nothing: the group can price it below the wholesale rate it charges its own tenants, capture the most price-sensitive customers, and leave its main brand untouched at 15 €. That is segmentation, not generosity, and it produces the cheapest offer on the network.

On the Orange network, the MVNOs' toughest rival is not another MVNO. It is the entry brand of the company that owns the masts.

The objection: is a house brand better served than a tenant?

It is the serious argument, and it only half holds.

Intuition says a brand owned by the network owner gets everything the network offers. On the Proximus network, the facts say otherwise. Scarlet, part of the group since 2008, broadcasts no 5G at all. yoin, an independent tenant on the same masts, sells 5G as a 1 € monthly option capped at 150 Mbit/s, and Mobile Vikings, although owned by Proximus, does not open 5G on its 10 GB plan. The owner restricts its entry brands to protect the value of its main brand, and does so by marketing decision, with nothing to renegotiate.

TADAAM makes the point even more sharply. On 15 September 2026, Telenet withdrew its subsidiary's 25 € unlimited mobile plan, described by the Belgian press as the cheapest on the market, citing a "conscious choice to allocate our investments where they add the most value". Existing customers keep it for now. New ones are pointed to BASE unlimited, listed at 39 € with a 30% discount for new customers, within the same group.

That leaves traffic priority, often raised against MVNOs. The traffic management policy of the Proximus network, reproduced on JIM Mobile's support page last updated on 7 November 2024, splits the bandwidth of a congested mast evenly among simultaneous users, the only exception being the Business Priority option for professionals. For independent MVNOs, wholesale contracts are not public, and the BIPT, Belgium's telecom regulator (IBPT in French), publishes its measurements network by network, never brand by brand. Nobody can therefore claim, with evidence, that a yoin customer comes after a Proximus customer at 6 pm outside the station.

Who decides when a brand changes network?

The owner for house brands, the contract for MVNOs. Both move.

Mobile Vikings moved from the Orange network to the Proximus network in February 2022, eight months after its takeover by Proximus, completed in June 2021 for 130 million euros. VOO has been moving its mobile customers to the Orange network in waves since October 2024, a year and a half after Orange Belgium took control. In both cases, the change of shareholder moved the customers.

edpnet, meanwhile, changed network three times without ever changing owner: Proximus, then Orange, then DIGI in February 2026, following its wholesale deals.

And the line between categories moves too. Telenet was an MVNO until 2016 and now owns a network; Mobile Vikings was an independent MVNO and has become a house brand. A brand's status has to be re-read after every takeover, which on this market means roughly once a year.

DIGI is neither

DIGI owns its own network, code 206 12, and borrows Proximus 4G through national roaming until 2029 where its own masts are still missing. It is a network operator under construction, not an MVNO, and edpnet, owned by its partner Citymesh, now runs on its masts.

Five checks to find out who owns your brand

None takes more than two minutes, and three can be done without leaving the plan's page.

• Does the name of a network group appear in the brand's legal notice or terms and conditions? It is the fastest test, and it settles the ownership question.
• Does a customer of the host operator have to change SIM card to join the brand? If they keep theirs, as Orange customers do at hey!, you are dealing with the owner.
• Are 5G and the maximum speed written in black and white on the tariff sheet? A house brand can be denied them by choice, an MVNO by contract.
• Does customer service run through the group's shops, or only through a digital channel? hey! answers by chat and WhatsApp from 8 am to 10 pm, with no shop.
• Does the advertised discount apply "for the length of the contract" or for twelve months? As of 29 September 2026, hey! grants a lifetime 2 € discount on its M plan for any order placed by 4 October, while Orange Mobile Medium goes from 16 € to 23 € in month thirteen.

We do not subscribe to any of these plans and we measure nothing in the field: this page cross-checks the official pages of groups and brands, the Belgian press and public tariff sheets, surveyed between 10 and 29 September 2026. The market sorted on the month-thirteen price sits in our 5G plan ranking, host network shown on every line, and can be reordered in the comparison tool. The full brand-by-brand network table is in which network each Belgian mobile brand uses, and the calling features each brand enables in VoLTE and VoWiFi: which Belgian brands enable them.
