Top 7 best mobile plans 2026
The best Belgian mobile plan depends first on what you agree to sign, not on the network. At a comparable advertised monthly price, a 24-month contract with a handset included costs several hundred euros more over the term than a no-contract SIM-only plan — and you do not leave it under the same conditions. This ranking sorts seven plans available in Belgium on three figures only: the price for the first twelve months, the price applied from month thirteen once the promotion ends, and the total cost over 24 months with the handset counted separately.

How do you read the price of a Belgian mobile plan without getting it wrong?
By looking at two figures instead of one. The price shown on the poster and on the operator's home page is almost always a promotional price valid for twelve months; the price actually billed from month thirteen sits elsewhere, in the specific terms, in 8-point type.
The gap is not trivial. On Belgian unlimited plans it commonly runs between €5 and €15 a month, which is €60 to €180 over the second year. A plan advertised at €20 that reverts to €32 in month thirteen costs €384 over two years, not €480 — and, more importantly, it costs more than a competitor advertised at €25 and billed €25 throughout.
My method fits on one line: I note the month 1-12 price, the month 13-24 price, I multiply and I add. That 24-month total is what orders this ranking, and nothing else. The introductory price never appears on its own.
Is the handset included with the plan really cheaper?
Rarely, and never free. A smartphone "included" or "for €1" is a handset balance: the price of the device, possibly discounted, split into 24 instalments sitting alongside the plan. It is not a discount, it is a payment plan.
Two practical consequences, which I watched arrive at the counter every week. First: if you cancel in month 14, the plan stops but the handset balance falls due, in one payment. Second: that balance carries no right to number portability or fee-free cancellation — those protections cover the telecoms service, not the financing of the device.
The honest calculation therefore compares two totals: on one side the plan with handset over 24 months; on the other the same data allowance as SIM only over 24 months, plus the outright Belgian retail price of the phone. In most cases checked, the second column is lower — and it leaves you free to walk away.
What is a virtual operator, and what do you give up?
A virtual operator rents the network of a physical operator and sells its own plan on top. In Belgium four players run their own mobile infrastructure — Proximus, Orange Belgium, Telenet/BASE and DIGI, the most recent arrival — and every other brand relies on one of them.
What you give up is narrower than people assume: the mast is the same, the coverage is the same, the theoretical throughput is the same. What changes is service and margin — traffic priority during congestion depending on the wholesale agreement, sometimes narrower roaming options, online-only customer service, and no shop to walk into.
What you gain is measurable: at equal data allowance, the gap against the corresponding incumbent commonly runs from 30 to 60 %. For a reader using under 20 GB a month who does not need a counter to speak to, it is the most profitable trade-off on the Belgian market.
How many gigabytes do you actually need?
Fewer than the poster sells, in the vast majority of cases. Before choosing an allowance, open your current operator's customer area and note your consumption for the past six months, month by month. That is the only figure that matters, and it costs nothing.
Some orders of magnitude to read it by: an hour of music streaming uses roughly 70 to 150 MB depending on quality; an hour of standard-definition video, 0.6 to 0.9 GB; the same hour in high definition, 2 to 3 GB. Usage without mobile video rarely exceeds 5 GB a month; daily video on the commute climbs past 30 GB quickly.
Two traps recur. Tethering is deducted from the same allowance, which changes everything if the phone is the modem for remote work. And a so-called "unlimited" plan almost never is in the strict sense: a fair-use clause caps heavy usage or throughput beyond a certain threshold. The threshold is in the general terms; if it is not there, ask for it in writing before signing.
How do you leave a Belgian mobile contract?
Through a precise procedure, in a precise order. Never cancel yourself first if you want to keep your number: it is the new operator that triggers portability and cancels the old contract on your behalf. Cancelling first means losing the number.
In practice: you choose the new plan, you provide your phone number, your customer number with the old operator and the identifier of your current SIM card, and the transfer runs within one working day, with a service interruption measured in minutes or hours, not days.
On fees, Belgian telecoms law frames the exit: an open-ended contract, or a fixed-term contract past six months of performance, can be cancelled without an early-termination fee. The balance of a financed handset remains due, and a discount conditional on the contract term may be clawed back — that is written in the specific terms, never on the poster. If you hit a wall, the Telecommunications Ombudsman Service is the free competent contact, and the BIPT is the market regulator.
Comparison table
Methodology : Each plan is taken from the rate card published by the operator or, failing that, from public comparisons of the Belgian market, as at 24 August 2026. Three figures are recorded: the price for the first twelve months, the price from month thirteen, and the 24-month total excluding any handset. The balance of a financed phone is always counted separately from the plan, never folded into it. Where an operator does not publish a figure, the cell stays "not published": no value is reconstructed. No link in this ranking is monetised; links to operators are neutral and nofollow. Belgian mobile rates move several times a year: always check the date of the reading before relying on a figure.

Frequently asked questions
Which is the cheapest mobile plan in Belgium right now?
On the rate card checked on 24 August 2026, DIGI's entry offer is the lowest on the Belgian market, at €3 a month for 7 GB with unlimited calls, no contract. On a more comfortable allowance the same brand shows 60 GB at €9 a month. These are entry prices: check how long they apply before signing.
Can I keep my number when switching operator?
Yes, and it is free. Mobile number portability is a right in Belgium. The new operator triggers it and cancels the old contract for you. So never cancel yourself before subscribing elsewhere: a cancelled number is a lost number.
After how long can I cancel without a fee?
Belgian telecoms law allows fee-free cancellation of an open-ended contract, or of a fixed-term contract past six months of performance. Note that this covers the service. The balance of a phone financed with the plan remains due, and it is payable.
Does a virtual operator get worse reception than an incumbent?
The mast is the same, so the coverage is the same. What can differ is traffic priority during local congestion, depending on the wholesale agreement signed with the host operator, and the breadth of roaming options. In everyday use, the difference does not show.
What happens when my data allowance runs out?
Three behaviours exist depending on the plan: data is cut until the next month, throughput is reduced, or usage is billed above the plan. The third is the most expensive and the one to check before signing. Most Belgian operators let you cap or block out-of-plan usage from the customer area.
Does my Belgian plan work everywhere in Europe?
Within the European Economic Area, yes, subject to a fair-use policy: calls, texts and data are deducted from your Belgian allowance. The United Kingdom and Switzerland are outside it and are billed under each operator's own rate card. Outside Europe, per-minute and per-megabyte rates climb very fast: set a cap before you travel.
Is a prepaid card better than a plan?
Prepaid remains sensible for low, irregular use, a second line, or a short stay. As soon as you regularly pass a few gigabytes a month, the per-gigabyte cost of prepaid exceeds that of a no-contract SIM-only plan, which offers the same freedom to leave. In Belgium, activating a prepaid card requires identifying the holder.
