Cancel a mobile plan without fees: when and how

Yes, and sooner than most people think. A Belgian mobile plan can be terminated with no fee from the end of the sixth month after it takes effect, even when signed for 24 months. Before that point, the operator can only charge the plan up to month six. The financed phone stays due. Always.

After how many months can you cancel without fees?

Six months, counted from the contract's entry into force.

The FPS Economy puts it plainly: a telecommunications contract, fixed-term or open-ended, can be terminated without reason and free of charge after six months. The rule is federal. It applies in Namur as in Brussels or Ghent, and it does not depend on any brand: Proximus, Orange Belgium, Telenet and its BASE brand, DIGI Belgium, or a virtual operator such as Mobile Vikings or Scarlet, both running on the Proximus network.

The starting point is the entry into force. In principle, that is the activation of the line, not the day you signed at the counter. A few days apart, sometimes two weeks when the SIM card comes by post. The date is on the first bill.

On an open-ended contract, the question does not even arise: no fee, from day one.

Does cancelling before six months cost more than staying?

No. Exactly the same.

The fee the law allows during the first six months is capped at the plan charges remaining until the end of the sixth month. Run the numbers on an unlimited plan at €39 a month, 24-month commitment, post-promotion price not published, rate card recorded on 24 August 2026. Leaving at the end of month two means paying two months used plus four months of fee: €234. Staying until the end of month six means paying six months: €234. The counter does not move by a single euro. What changes is that the line stops sooner, and sometimes that is all you want.

I spent three years in the cancellations department of a Belgian virtual operator, and this is the sentence I repeated most often on the phone: you lose nothing by leaving now, you gain nothing by waiting, except on the phone.

What does an exit cost, month by month?

The table uses the same case: a €39 monthly plan, and the site's reference device, €599 including a €1 down payment and €598 financed linearly over 24 months, amortisation schedule recorded on 24 August 2026.

Two readings. On the plan, the column never drops below €234: the first six months are paid whatever you do. On the device it is the reverse, every month that passes lightens the exit bill by €24.92. The price applied at month thirteen is published by none of the operators in the recorded rate card: I do not estimate it.

Which amounts stay due after six months?

Only one, in principle: the residual value of the product received at signature.

The FPS Economy phrases it this way: if you received a phone with the plan, the additional fee cannot exceed the residual value of the product at the time of termination. The operator must attach a month-by-month amortisation schedule, over 24 months at most. The full mechanism is taken apart in the article on the €1 phone and its 24-month credit.

On your closing bill, expect three lines, no more:

• the plan pro rata, up to the effective end date;
• the handset balance, read from the amortisation schedule for the month you leave;
• the early termination fee, only if the end falls before the close of the sixth month.

A fourth line labelled "administration fee" or "benefit clawback" on the plan alone, after six months? Ask which clause it rests on. The law provides for nothing of the kind.

Which channel makes a termination valid?

Writing. The phone is not enough.

This is the most common trap, and it costs months of plan charges. The FPS Economy lists a letter, an email and a text sent to the number the operator has set up to receive terminations. A call to customer service can get you your exit figures. It does not count as a termination. At Proximus, the help page on changing or cancelling a subscription details the operator's own channels; the written-form rule itself comes from the law.

Your written notice must carry five items:

• the account holder's name, as shown on the bill;
• the line number and the customer number;
• an unambiguous sentence: "I terminate the contract for line …";
• the end date you want, taking the notice period into account;
• a request for written confirmation and the exit figures, handset balance included.

A timestamped email does the job. Registered post remains the strongest proof when the relationship has soured.

What notice period can the operator impose?

The one in your contract, and two months at most according to the FPS Economy.

You often read thirty days. That is the notice period in many Belgian general terms, not the legal ceiling. Open yours before setting a date: a one-month notice sent at the start of the sixth month puts the end of the contract past the threshold, so with no fee.

Should you cancel yourself when switching operators?

No, never if you care about your number. The new operator requests the port and ends the old contract. A number you terminate yourself is a released number, and it can no longer be ported. The exact order is set out in the article on switching operator while keeping your number.

Seven situations, seven answers

What if the operator charges anyway?

Write once, citing the entry-into-force date and the six-month rule, and ask for a reasoned answer. If it does not come, the Telecommunications Ombudsman Service handles the dispute at no cost to you. The BIPT publishes the framework for terminating Belgian contracts, and that is the text to have in front of you, not the brochure.
