Choosing a Mobile Service Provider/SIM

Get a prepaid SIM from a kiosk on your first day, and worry about a contract later. You will want a Belgian number long before you have the commune registration a contract requires — and number portability means switching later costs you nothing.
At a glance
Start prepaid
A prepaid SIM from a nearby kiosk works the same afternoon you land, with no registration, no bank account and no commitment. Lyca is generally the cheapest starting point; the shops that sell it are the same ones selling international calling cards, and there is one near most stations.
Prepaid suits you if you would rather not sign anything, if your stay is short or uncertain, or if you already have a phone and simply need a Belgian number.
You need the number before you need the deal. Banks, the commune, landlords, delivery drivers and every two-factor code want a Belgian mobile in your first fortnight — and a contract wants a commune registration you do not yet have. Prepaid first is not a compromise, it is the correct order.
Move to a contract once you have a flat
Contracts give more data, better rates and the option of bundling. To sign one you normally need to be registered at your commune, and usually a Belgian bank account for the direct debit — which is why this waits until your permanent address is settled.
At that point the sensible move is a household bundle: several SIMs, home internet and television on one bill, which is materially cheaper than buying each separately. Proximus, Telenet/Base and Orange are the main operators; Scarlet and the smaller resellers sit underneath them on the same networks for less money and fewer frills.
Port your number, do not abandon it
By the time you switch, your prepaid number is on your bank records, your commune file, your employer's system and every account you have opened. Number portability is free and takes a few days — ask for it when you sign. Starting again with a new number means updating all of it.
Worth checking before you sign
- Contract length and what it costs to leave early.
- Calls to India — bundles vary enormously, and the cheapest domestic plan is often poor for international calling.
- EU roaming, included by regulation but with fair-use limits worth knowing.
- Coverage at your actual address. Ask neighbours rather than reading a coverage map; Belgian indoor coverage varies street by street.
