Cut your telecom bill: the six-step method

Cutting a telecom bill in Belgium comes down to a sequence: work out your full rate once the promotion has ended, check whether a recent increase opens a free exit, call the retention team with a competitor price in hand, and move elsewhere if no commercial gesture arrives.

The retention team is the unit an operator activates when a customer announces they are leaving. It does not sell the public price list: it holds unlisted discounts that can be applied to a subscription already running. It is the only door through which an existing customer gets the new-customer price. You still have to knock at the right moment.

How do you cut a telecom bill in Belgium?

In six steps, in order: cost the full rate, identify the legal exit window, prepare a competitor price, call retention, switch to the sub-brand if you are refused, break the bundle if the gap is still too wide.

What you need: your latest itemised bill, the contract start date, and twenty minutes on the phone. No fees, no paid intermediary. Allow a week from the first call to the new bill if you stay, three to four weeks if you leave.

What are you actually paying today?

Take the amount excluding any promotion, not the one on your first bill. Until that figure is on the table, no comparison holds: you risk setting an introductory price against a full rate, which distorts everything.

On a Belgian statement, three lines deserve a careful read. The base price of the bundle first. Then the options that have piled up: an extra set-top box, a second SIM card, a sports package, an assistance plan. Finally the out-of-plan charges, which point to a badly sized subscription rather than an overpriced one.

What it really costs is calculated over twenty-four months: full rate multiplied by the months remaining, plus the activation fees already paid, minus the launch discount which will not come back. A household that signed a bundle at 65 EUR/month for six months and then 89 EUR/month often discovers it has been paying 24 EUR more than it thought, every month, for a year and a half.

Are the 2026 increases already on your bill?

Probably. Proximus lifted its bundles by 2 to 4 EUR/month from January 2026. Telenet took another route: the landline, previously included in ONE packages, became a paid option at 2 EUR/month on 16 March 2026. Orange and EDPnet followed the same year. These moves apply to ongoing contracts, promotion finished or not, and many customers never noticed because the amount shifts by two euros on an eighty-euro bill.

When can you leave without paying a penalty?

Two windows exist. After six months of subscription, termination is free and needs no reason. And at every notified price increase, a free exit right opens for three months, even on a fixed-term contract.

The framework is set by Belgian regulation and summarised by the FPS Economy on terminating a telecom contract: past the sixth month you leave whenever you want, the contractual notice applies but cannot exceed two months. Before six months, you settle the monthly fees up to the end of the sixth month, and if a smartphone had been given to you, the additional charge is capped at its residual value at the time of termination. A Belgian telecom contract also cannot run longer than twenty-four months: beyond that it automatically becomes open-ended.

The second window is the least known, and the most useful. The IBPT sets out what happens when the operator changes the contract: an increase in the rates applying to your contract lets you terminate free of charge, and that right stays open for three months after the notification. Any other change to the conditions must be announced at least one month in advance, with the same exit right.

How do you negotiate with the retention team?

By calling customer service to announce a cancellation, not to ask for a discount. A discount request stays at the first level; announcing a departure triggers the transfer to the team that holds the budget.

Prepare three things before dialling. The exact price of an equivalent competing offer, with the operator's name and the package — not "I have seen cheaper elsewhere". Your years as a customer, which genuinely weigh in the decision. And the amount you are willing to pay, decided in advance, so you do not fold at the first counter-argument.

Then name explicitly what you want. At Proximus, the benefit reserved for loyal customers often takes the form of a free device rather than a discount on the bill, it is not publicly advertised, and not every adviser offers it unprompted. Asking for it by name changes how the call ends. General customer service is reachable on 0800 33 800.

Do you really have to threaten to leave?

Not threaten: announce. The distinction is practical, not moral. An adviser only transfers a file to retention once it is flagged as a cancellation in progress, and that flag requires a clear request. If you have no intention of leaving, the call ends on the public price list. The corollary is that you should first check that a competing offer genuinely exists at your address, otherwise you are negotiating without a net.

The trap to avoid: the non-renewable discount

The discount wrung out over the phone is very often temporary. Six or twelve months, then back to the full rate with no warning letter. Threads on the Proximus support forum come back to this point regularly: the customer believes they renegotiated their subscription, when in fact they obtained a deferral. Note the end date in your calendar on the day of the call, and have the duration confirmed in writing, by email or in your customer area. Without a written date, the discount does not exist.

Should you switch to your operator's sub-brand?

Often, yes. It is the most profitable move on the Belgian market, because it keeps the network and changes only the brand, the price and the service level.

The setup is specific to Belgium: the big groups sell the same product under a low-cost brand. Scarlet belongs to the Proximus group and runs on its network. Mobile Vikings has moved under the Proximus umbrella. hey! is the budget brand of the Orange group. The network does not change, coverage does not change, the bill does.

The figures published by L'Avenir on 26 January 2026 put a number on the gap: 239.88 EUR a year for a mobile subscriber leaving Proximus for Mobile Vikings, 168 EUR a year for one leaving Orange for hey!. On the fixed side, the Scarlet Trio bundle, which combines unlimited internet, digital TV and a landline, is listed at 45 EUR/month, and 50 EUR/month in its version with mobile.

Sources: L'Avenir (26 January 2026 and 17 February 2025), Scarlet (2026 bundle comparison), Test-Achats (Proximus 2026 subscriptions). Figures collected in August 2026, to be rechecked at your address.

Breaking the bundle: how much does it actually return?

Up to 707.88 EUR a year for a family of four. The example costed by L'Avenir in February 2025 pairs a Scarlet Trio at 42 EUR/month for internet and TV with four DIGI SIM cards at 5 EUR/month, against an all-in-one bundle from a major operator.

The logic is simple: the big operators charge for the convenience of a single bill, and that convenience costs more than the multi-product discount they grant in return. The more mobile lines a household has, the more the trade-off tilts towards the broken bundle, because the per-line surcharge multiplies.

The reverse is true as well, and it should be said: for a single person with one line, the gap melts. Your operator's convergence discount, the activation fees of a second contract and the loss of the integrated landline can erase the gain. Run the calculation over twenty-four months before cutting anything, and remember that two contracts mean two renewal dates to watch.

What if your operator says no?

You leave. Easy Switch, free and supervised by the IBPT, has the new operator cancel the old contract, transfers the mobile number and coordinates the internet handover to limit downtime.

The procedure requires you to give the new operator your Easy Switch code and your customer number, both printed on your bill. It handles the rest, including the cancellation, which avoids the classic scenario of two subscriptions billed in parallel for a month.

If termination fees appear despite the six-month rule or the exit right linked to an increase, the path is mapped out. A written complaint to the operator first, with the date of the tariff notification. Then a filing with the Ombudsman Service for Telecommunications, free of charge, which handled 15,087 requests in its 2025 annual report published in March 2026. Simply announcing that filing unblocks a share of cases.

How long does switching take?

Allow one to three weeks. Mobile number portability is the fast part, often settled within one working day. The internet handover depends on the technology at your address and on a possible technician visit. Never cancel yourself before the new contract is active: that is exactly what Easy Switch exists to prevent.

The mistakes that cost the most

Four come up constantly. Comparing two promotional prices with each other, when they share neither duration nor exit rate. Negotiating without having checked that a competing offer genuinely exists at your address, which leaves you with no argument. Accepting a discount without having its end date recorded. And letting the three-month window after a price-increase notification lapse, since that is the only moment you can leave without penalty mid-commitment.

A fifth, quieter one: keeping options you no longer use. A second set-top box in an empty bedroom, a sports package out of season, an inactive second SIM card. Each weighs two to eight euros a month, and nobody cancels them because nobody rereads their bill.
