VoLTE and VoWiFi: which Belgian brands enable them

Both features are free and neither is decided at mast level. They are decided brand by brand. On the Proximus network, the four labels surveyed enable them; on the Orange network, the gap between Orange and VOO is still open. Surveyed on 20 September 2026, host network shown.

3G is gone, 2G shuts down in 2028

The question changed nature in two years.

Belgium's network operators unplugged their 3G one after the other: Orange started in January 2024, Telenet and BASE began theirs in September 2024, Proximus cut its own on 31 December 2024. That leaves two paths for voice on a Belgian handset. Either 2G, in service since the early 1990s, or 4G and 5G through VoLTE. Nothing in between.

And 2G carries an expiry date. On a page last updated on 13 August 2026, the BIPT, Belgium's telecom regulator, states that Orange, Proximus and Telenet/BASE have confirmed the shutdown of their 2G networks across 2028 and 2029, and advises looking now for an alternative for devices that still depend on it.

A brand that does not enable VoLTE is not withholding a comfort feature. It is putting you on a countdown.

VoLTE and VoWiFi, two free features and two different routes

VoLTE, for Voice over LTE, carries the call on the 4G or 5G radio layer instead of 2G: sound quality improves, the call connects in one or two seconds instead of five, and your data session no longer drops during the conversation. VoWiFi, for Voice over WiFi, carries the same call over your fixed internet line when the mobile signal is missing, in a basement, inside a well-insulated recent building, at the back of a shop.

Both are free. Minutes come out of the plan like any other call, and no Belgian operator surveyed bills them separately.

Both are switched on inside the handset, under the mobile network settings, labelled "Wi-Fi Calling" and "Calls over 4G". If the option does not appear on a handset that supports it, the phone is not what is missing. The operator-side authorisation is.

Why are two brands on the same network not equal?

Because neither feature lives in the masts.

Radio coverage is shared: a hosted brand uses the same masts as its host, and that is the whole point of renting a network. VoLTE and VoWiFi live in the core network instead, on a calling platform that the owning operator has to open to the brand it hosts, plan by plan, while maintaining a list of approved handsets. That is a cost line, a support line and a negotiation. Nothing forces a host to grant it, or a brand to pay for it.

Orange says so plainly on its own page: the feature applies to its own subscribers, and the operator lists by name the plans that qualify. The masts are the same for everyone. The calling platform is not.

The brand-by-brand table, host network shown

Surveyed on 20 September 2026, from brand support pages, official communications and the Belgian telecom press. The right-hand column carries the date of the most recent public statement found, because on this subject the age of the information matters as much as the information.

Two readings come out of this table, and neither is the one an article about MVNOs usually produces.

The Proximus network is the only one where all four brands surveyed offer both features. A Scarlet subscriber at 8 € and a Proximus subscriber at 49,99 €, thirteenth-month prices surveyed on 15 September 2026, place their calls over the same route, with the same sound quality. On that network the feature is not part of what you give up by moving down the range, whereas 5G is: Scarlet stays on 4G.

On the Orange network, the internal gap is the widest on the market. hey!, at 5 € a month, offers both features; VOO, on the same masts, is still completing its switchover. The cheapest brand on the network is therefore better equipped on this point than one of the most established, and the coverage rankings published by the regulator say nothing about that gap, because they measure masts.

Coverage is rented, the calling platform is negotiated. Two brands can pick up the same signal and not make the same phone ring.

Does the Belgian regulator know the brands that rent?

The BIPT keeps a consumer page on calls and texts over VoWiFi. It explains the feature, tells you to check with your operator, then points to three destinations: Orange, Proximus, Telenet/BASE. No hosted brand appears.

The regulator is right on the substance, since it regulates networks and a brand that rents one is not a network. The consequence stands nonetheless: the only official Belgian source on the subject does not answer the question a large share of the market is asking.

VOO is catching up, and that is the serious objection

The objection holds, and it has to be put before any conclusion.

VOO began moving its mobile customers onto the Orange network in October 2024, in successive waves, and that move brings VoLTE and VoWiFi with it. The gap in the table is therefore not a permanent choice: it is work in progress, on a detailed timetable the operator does not publish. Same movement at DIGI, whose support pages still denied Wi-Fi calling in early 2025 while users were already seeing it work on iPhone.

The consequence runs two ways. A feature table is a snapshot, valid for today's decision, wrong somewhere within six months, which is exactly why it carries a date. The most complete public list found online was published on 21 August 2024 and edited a week later, before DIGI sold mobile plans at any scale, and it is still quoted as is two years on.

One line does not move, the regulatory calendar. In 2028 and 2029, VoLTE stops being a selling point and becomes the condition for a phone that rings.

Can your internet connection block Wi-Fi calls?

Yes, and that is the second half of the problem.

VoWiFi runs through your router, so through your fixed internet provider. Several Belgian connections are documented as unreliable with this traffic: the call connects badly, drops, or the icon never appears even though the mobile plan supports it. The cause then sits on the fixed side, and switching mobile brand will fix nothing at all.

A second limit comes from location: neither feature is guaranteed from abroad, and a VPN presenting a foreign IP address is enough to break both. Check your brand's rule before relying on them on holiday.

Five checks settle the matter, and all of them can be done from the sofa.

• Does the option appear in your handset settings? Missing on a recent phone sold in Belgium, it signals a missing operator-side authorisation rather than a hardware fault.
• Does the plan's technical sheet name both features? The commercial homepage almost never mentions them; the tariff sheet or help page often does.
• Was your handset sold for the Belgian market? An imported model may never receive the carrier settings that reveal the option.
• Does your fixed internet provider pass this traffic? Test on a Wi-Fi network other than your own before blaming the mobile plan.
• Does a call connect in aeroplane mode with Wi-Fi on? That test is conclusive: if the conversation goes through, VoWiFi is genuinely working.

Is a free feature worth switching brands for?

No, not on its own. Yes, when it comes on top of something else.

The calculation, surveyed on 15 September 2026 on the Orange network, thirteenth-month prices: hey! asks 5 € a month and provides both features, Orange Mobile Small asks 15. Ten euros a month, 120 € a year, for the same masts and the same calling route. VoLTE alone does not justify paying three times more, and it does not justify staying put either.

If your brand does not enable it and the mobile signal stops at your front door, however, VoWiFi becomes the only free answer to the problem. An unapproved signal booster is illegal in Belgium and the BIPT can seize it. A femtocell has to be negotiated with the operator. An outdoor antenna costs more than a full year of subscription with the cheapest brand on the same network.

We do not test these features in the field and we measure nothing: this page cross-checks operator support pages, official communications and the Belgian telecom press, surveyed on 20 September 2026. The market sorted on the thirteenth-month price sits in our 5G plan ranking, host network shown next to every line, and can be reordered in the comparison tool. We have covered elsewhere which network each Belgian mobile brand uses and the difference between 5G standalone and non-standalone, which governs native 5G voice.
