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.
Lowest price recordedThe newcomer has moved the Belgian price floor: 7 GB with unlimited calls at €3 a month, 60 GB at €9 a month, no contract. The contract is short and readable, which is rare. Check before signing: coverage at your address, the infrastructure being younger than that of the three incumbents.

Best trade-offVirtual-operator pricing on the Proximus network: the most comfortable trade-off on the Belgian market for anyone who wants incumbent coverage without incumbent pricing. Plans start around €10 a month. Service is entirely online, which suits poorly anyone who wants a counter.
Cheapest unlimitedThe cheapest unlimited plan among the incumbent brands recorded, at €39 a month on the Telenet/BASE network. The gap against DIGI or Mobile Vikings stays wide on small allowances: BASE becomes interesting once you genuinely pass 50 GB a month.

Own networkAn unlimited plan at €40 a month on its own infrastructure, with a dense shop network and customer service reachable other than online. That is what you are paying for: the rate is consistent with the incumbents, not with the virtual operators.
For an existing household customerAn unlimited plan at €41.16 a month. Taken alone, the mobile plan has no pricing argument; it regains one inside a bundle with the household's fixed internet, where the convergence discount changes the maths. Then check what the bundle price becomes once the promotion ends.
