SIM Card in Brussels: The Honest Expat Guide (2026)

Getting a SIM card in Brussels is one of the first things worth sorting out after you land, because almost nothing in Belgium works smoothly without a Belgian mobile number: your bank app, your commune’s appointment system and most delivery couriers all want to text you a code. The good news is that a SIM card in Brussels is cheap, quick to buy, and with the right ID, ready in minutes. This honest guide covers the three networks, prepaid versus contract, the ID rules Belgian law requires, a day-one eSIM, and home internet in Brussels once you have a lease.

The three networks you can actually use in Brussels

Belgium runs a compact, three-operator mobile market, and you will find shops for all three within a few minutes of nearly any metro or tram stop in central Brussels.

• Proximus is the former state operator, with the widest coverage and strongest 5G, including deep into the metro tunnels. The safe default if reliability matters more than price.
• Orange Belgium covers the capital well and, since acquiring cable operator VOO, increasingly bundles mobile with home internet.
• BASE, owned by Telenet, is the value player, usually cheapest on prepaid bundles.

For a first SIM card in Brussels, most expats pick Proximus for coverage or BASE for price. Budget resellers such as Mobile Vikings and Lycamobile run on the Telenet and Orange networks.

Prepaid or contract: which SIM card in Brussels suits you

Your first SIM card in Brussels should almost always be prepaid. All three networks sell genuine pay-as-you-go SIMs (Proximus calls it Pay&Go+, Orange calls it Tempo, BASE just calls it a prepaid card), and none need a Belgian bank account or a credit check, so you can walk out connected the same day.

Switch to a contract later only if you want a subsidised handset, a fixed bill on direct debit, or a bundle pairing mobile with home internet in Brussels. Contracts usually need a Belgian bank account or SEPA card and, for non-EU residents, your residence permit; they typically run 12 or 24 months. There is no rush, since you can port your prepaid number to a contract at any time.

Typical prepaid prices in 2026. Always confirm the current promotion on the provider’s own site, since pricing changes often.

BASE’s bundles are the simplest choice for residents who want data, minutes and texts in one price. Orange’s Tempo suits light users who add data as needed, and Proximus Pay&Go+ rewards a bigger top-up with more bonus data.

Documents you need to buy a SIM card in Brussels

Belgium was an early mover on SIM registration. Since December 2016, every prepaid SIM card in Belgium must be linked to a verified identity document before it works, and an unregistered card cannot call, text or use data. Registration takes minutes at the counter.

• EU citizens: a passport or national EU ID card is enough to buy and register any prepaid SIM.
• Non-EU nationals: bring your passport. BASE’s own app-based registration accepts a Belgian ID, an EU ID or an international passport, and staff in any store can register a passport in person even where the online portal is built around a Belgian eID reader.

A contract SIM additionally needs a Belgian bank account or SEPA card and, for non-EU residents, your residence permit. Stay on prepaid until you have these.

Where to buy a SIM card in Brussels. Addresses and hours change, so use each network’s store locator to find the branch nearest you before travelling.

1. Operator stores: Proximus, Orange and BASE have branded shops across Brussels, including inside City2, Woluwe Shopping and along Rue Neuve. Locators: proximus.be, orange.be and base.be.
2. Airport counters: Proximus and Orange counters in the Brussels Airport arrivals hall sell prepaid SIMs before you reach the city.
3. Supermarkets and press shops: fine for topping up an existing card, but staff usually cannot register a new one, so buy the card itself at an operator store.

eSIM: staying connected on day one

There is always a gap between landing at Brussels Airport and reaching an operator store, and you do not want to be offline for your taxi app or your bank. A travel eSIM closes that gap: install it before you fly, and you have data the moment you land in Belgium.

Reliable eSIM options for Belgium include Airalo, Saily and Yesim. The trade-off: an eSIM is instant and needs no ID check, but is data-only, with no Belgian number, and costs more per gigabyte than a local plan. A small eSIM for your first days, then a proper SIM card in Brussels for a real number, is the sensible approach. Your phone needs to be eSIM-compatible and unlocked, true of most recent handsets.

Home internet in Brussels: fibre and cable options

Once you sign a lease, home internet in Brussels depends on which network reaches your building: the city is a patchwork of Proximus fibre and cable-turned-fibre from VOO, now owned by Orange Belgium, across the southern half of the city. Always check availability at your exact address before committing.

Orange and budget brand Scarlet resell capacity over the Proximus and VOO networks, so compare both once you know which infrastructure reaches your building. Installation timing depends on whether fibre already reaches your address, so ask for a firm slot when you order, and treat a prepaid SIM card in Brussels tethered to a laptop as your stopgap.

A quick word on privacy and streaming

Belgian internet is fast and open, but many arrivals want their home-country streaming, or a secured connection on public Wi-Fi around Brussels cafes and the metro. A VPN such as NordVPN handles both, optional but worth knowing about.

Frequently Asked Questions

Can I buy a SIM card in Brussels without a residence permit?

Yes. A prepaid SIM card in Brussels only requires a valid identity document. EU citizens register with a passport or national ID card, and non-EU visitors register with a passport alone. A residence permit is not needed for prepaid, though it becomes necessary for a contract plan.

Do I have to register my prepaid SIM with ID in Belgium?

Yes. Since December 2016, every prepaid SIM in Belgium must be linked to a verified identity document before it can call, text or use data. The provider handles this at the counter or through their app when you buy, so bring your passport or EU ID.

What is the cheapest SIM card in Brussels for a resident?

For most residents, BASE’s EUR 10 prepaid bundle (1 GB, 40 minutes, 250 SMS) is the best value deal, and its EUR 15 and EUR 25 bundles scale up cleanly. Orange’s Tempo Data Boost suits users who mostly want calls and add data as needed.

How long does home internet in Brussels take to install?

There is no fixed timeline for home internet in Brussels, since it depends on whether fibre already reaches your building or a technician visit is needed. Order the moment you sign your lease and use prepaid mobile data as a stopgap.

Should I get an eSIM or a physical SIM card in Brussels?

Get both, in sequence. Install a travel eSIM before you fly for data on landing, then buy a physical SIM card in Brussels within your first few days for a real number and cheaper long-term data. The eSIM covers the gap; the local SIM is permanent.
