Internet + Mobile With the Same Provider: Worth It?

Bundling internet and mobile with one provider simplifies your bill and unlocks a convergence discount. But that rebate is calculated on high standard prices: in July 2026, a combined bundle often lands around €60 to €100/month, while two well-chosen separate offers drop below €40. Here's when bundling is worth it, and when splitting wins.

Convergence means subscribing to several services — internet, mobile, TV, landline — with a single provider to earn a rebate and a single bill. It's the core of Orange's "Love" bundles, Proximus "Flex+" or Telenet "ONE". The idea is appealing, but everything depends on the base price the discount applies to.

Is bundling internet and mobile really cheaper?

Not always. The convergence discount is real, but it applies to standard prices often higher than those of low-cost operators. Bundling simplifies your bill; it isn't automatically the cheapest option.

Take Orange: a Love bundle applies -10% on internet and -25% on each mobile plan added (Orange.be, June 2026). On paper, that's generous. But the rebate starts from a €43/month internet plan and a mobile plan that isn't the cheapest on the market. Once the discount is applied, the total still sits above what an entry-level internet plan and a DIGI mobile plan cost taken separately.

The number that matters is never "how much the discount saves me" but "how much I pay in total, every month, after the promos end". A Proximus Flex+ shown at €66.99/month for 6 months reverts to €101.99/month afterward (Proximus.be, July 2026). The convergence discount does nothing to change that scheduled rise.

How does the discount work when you bundle?

In two ways: a percentage rebate on the subscriptions, and doubled mobile data. Both reward stacking services with one provider.

The percentage rebate is the most visible. At Orange, the Love bundle takes 10% off internet and 25% off each SIM, and these discounts last as long as the bundle exists (Orange.be, June 2026). Other operators prefer a fixed rebate: Proximus deducts up to €45/month for the first 6 months on a Flex+ internet + TV + mobile (Proximus.be, July 2026), which is spectacular at first, then evaporates.

The second lever, less known, is doubled data. Proximus, Orange and VOO double the data allowance of the mobile plan as soon as it enters a bundle — a 6 GB plan becomes 12 GB, at no extra cost (Abonnement-Tv-Internet.be, 2026). The only exception is Scarlet, Proximus's low-cost brand, which doesn't double the data. For a heavy user, that doubling matters more than the rebate in euros.

Why does data double inside a bundle?

It's a retention tactic: the operator gives you more data to make leaving feel psychologically costlier. The doubled plan only exists while the mobile stays in the bundle. Remove the internet, and the mobile data drops back to its original allowance. So the data bonus is never a given — it's a condition tied to bundling.

How much does an internet + mobile bundle cost in Belgium?

Between about €46/month for an Orange entry offer and over €100/month for a high-end fibre bundle. The real price depends on the speed, the number of SIMs and the state of the promos when you subscribe.

Here are the prices collected in July 2026 from operator websites, Astel and Abonnement-Tv-Internet.be, excluding temporary promotions unless noted.

Indicative prices, check at your address. The Proximus and Telenet bundles include TV; the Orange Duo and the DIGI setup do not.

The gap is striking. A DIGI setup (5G Home internet at €7/month + 60 GB mobile at €9/month) costs €16/month with no convergence discount at all (Test-Achats, 2026). It includes neither TV nor a landline, and the 5G internet depends on coverage at your address, but the gap with a traditional bundle often exceeds €50/month.

Is it better to take everything with one provider or split?

Splitting is often cheaper, bundling is simpler. The choice depends on what you value: budget, or the peace of mind of a single bill and one customer service.

Bundling wins when you want TV, a landline, several SIMs and doubled mobile data: then the convergence discount and doubled data offset part of the price. A family of four lines on Orange Love recovers -25% on each, which becomes significant.

Splitting wins as soon as budget comes first. A concrete example: instead of a Proximus bundle at €101.99/month after promo, an entry-level internet around €30/month plus a DIGI 60 GB plan at €9/month cap out below €40/month, for an equivalent internet + mobile use without TV. Over twelve months, the gap exceeds €700.

Does a DIGI internet + mobile bundle exist?

Not as a discounted bundle, but DIGI offers both services at rock-bottom prices independently: a 5G Home internet at €7/month (which uses the mobile network instead of a fixed line) and mobile plans from €3/month, up to 60 GB for €9/month (Test-Achats, 2026). You assemble your own "bundle" with no loyalty clause. The trade-off: no doubled data, no integrated TV, and 5G Home requires good coverage at your address.

What traps should you avoid with a combined bundle?

Three above all: the promo that hides the real price, the commitment that locks you in, and the discount that vanishes if you drop a service. Each can turn an apparent bargain into a heavy bill.

The first trap is the teaser promo. A Flex+ at €66.99/month for 6 months looks attractive, but it reverts to €101.99/month afterward (Proximus.be, July 2026): over 24 months, it's the full price that dominates. Always calculate the average cost over the term, not over the first months.

The second trap is the annual rise. Proximus, Telenet and Orange all raised their prices in January 2026 (Test-Achats, 2026). A bundle signed today may cost more in twelve months without you changing anything. The third trap is structural: the moment you cancel a block of the bundle, the convergence discount disappears on the rest. Dropping the mobile in a Love bundle sends the internet back to full price.

The real cost over 24 months

Over two years, the gap between bundling and splitting runs into the hundreds of euros. It's the duration that reveals the true price, once the promos are gone.

Let's compare similar contents (fixed internet + one mobile, no TV). A Proximus Flex+ at €66.99/month for 6 months then €101.99/month comes to about €2,397 over 24 months. A split setup — entry-level internet at €30/month + DIGI 60 GB mobile at €9/month — caps at €936 over the same period. The gap reaches nearly €1,460, at the cost of no TV and a second bill to manage.
