Proximus Mobile Unlimited: what does €49.99 buy?

Proximus Mobile Unlimited costs €49.99 a month, €14.99 more than the fastest unlimited plan from Mobile Vikings, which runs on the same antennas. That gap buys three things: standalone 5G, sold as 5G+, 300 GB usable across the European Union and a speed with no contractual cap. Few subscribers need all three.

A word of context for newcomers. Belgium has three mobile networks (Proximus, Orange and Telenet) plus DIGI, which is still building its own, and around fifteen brands that rent them. Some are MVNOs, mobile virtual network operators with no antennas; Mobile Vikings, yoin and Scarlet all belong to Proximus and use its network.

€34.99 for six months, or for twelve?

Both versions are in circulation the same week.

Test Achats, the Belgian consumer association, lists €34.99 instead of €49.99 for six months in its telecom promotions survey updated on 6 October 2026, for any order placed before 1 November. The listing on the comparison site Astel, consulted on 7 October 2026, shows the same price for twelve months. Our own readings had already seen the duration move: six months on 29 August and 10 September, twelve months on 15 September.

The stakes can be counted. Over 24 months, six months of discount comes to €1,109.76; twelve months, €1,019.76. Ninety euros separate two pages describing the same offer, and neither is necessarily wrong: the duration may depend on the sales channel. Have it written on the order form.

Either way, the price to remember is the one that follows: €49.99.

Proximus Mobile Unlimited against the other Belgian unlimited plans

Eight plans list 300 GB in Belgium. The table sorts them by host network, at the full rate, with no temporary discount.

Full prices: CallMePower (unlimited plans page consulted on 7 October 2026), Selectra (4 October 2026) and the Belgian daily L'Avenir (19 August 2026). European volumes: L'Avenir, 19 August 2026. Speeds: Mon-Abonnement-Gsm (22 July 2026) for Proximus, Test Achats (21 August 2025) for Mobile Vikings Basic and Fast, our reading of 15 September 2026 for Superfast. These are contractual ceilings, not measured speeds. The last column is our own calculation, at the full rate. One reservation: Selectra, on 4 October 2026, does not count Mobile Vikings among the unlimited plans, whereas Test Achats and L'Avenir give it 300 GB.

Read row by row, Proximus is the most expensive in its column and in every other. Read column by column, it is also the only one that ticks the last three.

What does 5G+ offer that the others lack?

A network core that is entirely 5G. The three Belgian networks carry what is called non-standalone 5G, where 5G antennas are still steered by 4G infrastructure. On 7 April 2026 Proximus opened the country's first standalone 5G, for business customers first, then for consumers in the summer. The commercial name is 5G+.

On paper there are three gains: calls go straight over 5G instead of dropping back to 4G, the identity data on the SIM card is better encrypted, and the network can reserve a slice of capacity for a given use, which mainly interests emergency services and companies. Proximus also promises lower power consumption on the phone.

One figure is missing, and it is the one everyone expects. The Proximus 5G page, consulted on 7 October 2026, publishes neither a speed nor a latency for 5G+. It only states that 5G+ covers the same area as its ordinary 5G. For that area, stick to the atlas of the BIPT, the Belgian telecom regulator (IBPT in French): 99.53% of the territory outdoors and 71.51% deep indoors, January 2026 data taken up in the BIPT review of 7 May 2026.

No brand renting the Proximus network opens 5G+ to its customers. The full mechanism is explained in our head-to-head on 5G standalone versus NSA.

Two phones, one dedicated eSIM

Today 5G+ only switches on with the Google Pixel 9 and Pixel 10. You also need a compatible eSIM, which Proximus supplies separately.

With an iPhone or a Galaxy, you pay €49.99 for a 5G that Mobile Vikings carries too.

On the Proximus network, a €14.99 gap with Mobile Vikings

Mobile Vikings belongs to Proximus and uses its network. Its Unlimited Superfast plan lists 300 GB, unlimited calls and texts, for €35. Mobile Unlimited asks €49.99. The gap is €14.99 a month, €179.88 a year, €359.76 over two years. The antennas are the same.

That money is not thrown away. It buys 5G+, if your phone can pick it up. It buys 200 more European gigabytes, since Superfast stops at 100 GB in the EU while Proximus lets all 300 travel. And it buys a higher speed ceiling, 1 Gbit/s advertised against 750 Mbit/s, a difference nobody notices on a six-inch screen. What remains is the shops and customer service of a network operator, which everyone values in their own way.

The toughest competition, though, comes from inside the house. Proximus Mobile Maxi gives 120 GB on 5G for €29.99: twenty euros less every month, €240 a year. And on 14 July 2026 the BIPT published an average consumption of 11.9 GB a month per Belgian mobile customer. Between that average and the 120 GB of Maxi there is already a factor of ten. I cannot see who, below 120 GB a month and without a Pixel, would keep Mobile Unlimited after looking at their own usage in the operator's app.

Who is €49.99 defensible for?

Three profiles, and they are narrow:

• the owner of a Pixel 9 or 10 who wants standalone 5G now, without waiting for a cheaper brand to get access;
• the traveller who uses more than 100 GB a month in the European Union, the point beyond which Mobile Vikings Superfast no longer keeps up;
• the subscriber who replaces a fixed line with a phone and goes past 120 GB, provided the Proximus network is the only one that carries properly at home.

If the third condition does not hold, look at the other networks before signing.

Do Orange and Telenet do better for less?

On roaming, yes. Orange Mobile Unlimited at €40, Telenet Mobile Unlimited at €41 and BASE 39 also let their full 300 GB travel in the EU, for €9 to €11 less than Proximus each month. The detail is in our roaming record by brand.

On standalone 5G, no: to our knowledge, neither Orange nor Telenet sells it to consumers at the date of this article. And those are different antennas. An unlimited plan at €39 on a network that carries poorly at your address is still a bad deal, whatever the table says.

We subscribed to none of these plans and measured neither speed nor latency: this page cross-checks the official Proximus page, the trade press and the readings of Belgian comparison sites, all dated. The rules on the word "unlimited", set by the BIPT communication of 21 February 2022, are covered in our article on the 300 GB rule. Plans sorted on the price in month thirteen, host network shown, are in our 5G plan ranking.
