Belgium – Landlines and Mobile Phones

What are the international dialling codes for Belgium, and what are the area codes for the most popular expat destinations?

Belgium’s country code is 32. To reach a Belgian number from another country, you dial your outgoing international access code (typically 00 or +), followed by 32 and then the local number — leaving out the leading zero. Callers abroad therefore use their international exit prefix, then 32, then the area code without its initial ‘0’, and finally the subscriber number.

All calls placed within Belgium require the leading ‘0’ trunk prefix. This is an important distinction: the zero is mandatory for domestic calls but must always be removed when dialling from overseas. To call out of Belgium internationally, the outbound access code is 00.

Belgian telephone numbers vary in total length depending on type — landline numbers contain nine digits in full, while mobile numbers contain ten. Belgium operates an open numbering plan: major cities use a one-digit area code (after removing the 0), while smaller towns have two-digit area codes.

The area codes for Belgium’s most popular expat destinations are as follows:

A point of potential confusion: Liège landlines also begin with 04 domestically, appearing internationally as +32 4… (nine digits in total), whereas mobile numbers take the form +32 4xx… (ten digits). If you are unsure whether you are dialling a Liège landline or a mobile number, counting the total digits is the most reliable check.

Mobile and GSM numbers always start with 04xx, with the subscriber portion consisting of six digits. Historically, the second digit indicated the network: Proximus numbers were allocated 047x or 0460, BASE received 048x, and Orange received 049x. However, mobile number portability has been available in Belgium since 2002, so these prefixes now only reflect the original allocation — a number beginning with 048x may have long since migrated away from the BASE network.

The emergency number 112 covers fire, ambulance, and police services across all EU member states. Operators responding to 112 calls can assist in the country’s official languages, in English, or in the language of any neighbouring EU country.

Who are the major landline providers in Belgium, and how can you contact them?

Fixed telephony, mobile services, and television in Belgium are largely dominated by three major groups: Proximus, Orange Belgium, and Telenet. For landlines in particular, regional geography plays a significant role in determining which providers are most relevant to you, and it is worth mapping this out before committing to a subscription.

Proximus is the national incumbent and the single largest operator in the country. As a semi-state-owned company with a history stretching back to the state telephone monopoly, Proximus provides the most extensive geographical reach in Belgium, including rural and remote areas. It offers landline, broadband internet, television, and mobile services across the whole country. Visit www.proximus.be or reach their customer service on 0800 33 800 (toll-free within Belgium). New landline connection typically costs around €50, though this installation fee is often waived when subscribing to a combined internet, TV, and phone package. Lines are normally activated within ten days of the request being processed. Always consult the official Proximus website for up-to-date pricing, as promotional rates change regularly.

Telenet is the second major fixed-line operator, with a particularly strong foothold in Flanders and Brussels. It operates a high-performance cable network serving around 58% of the Flemish population and offers broadband internet, digital television, and both fixed and mobile telephony. Telenet has a wide network of physical retail outlets concentrated primarily in Flanders and Brussels. Visit www.telenet.be or use their online chat or app for customer support.

Orange Belgium (including VOO) rounds out the trio of main fixed-line providers. Orange Belgium, part of the French Orange group, traditionally focused on mobile telephony, but its 2023 acquisition of VOO extended its footprint into fixed internet and cable TV across Wallonia and Brussels. If you are settling in Wallonia or the Brussels-Capital Region, Orange and VOO represent a competitive option for fixed-line services. Current plans and contact information are available at www.orange.be.

Scarlet is the budget-oriented alternative for those who want straightforward services at a reduced cost. Operating as Proximus’s low-cost brand, Scarlet functions primarily as a digital-only provider with no physical storefronts. Its offerings and pricing can be explored at www.scarlet.be.

Most Belgian operators offer bundled subscriptions combining landline phone, high-speed internet, digital television, and sometimes mobile service into a single package. Bundling typically unlocks discounts or eliminates installation fees. Confirm all current pricing and promotional conditions directly with your chosen provider before signing up. The national regulator, the Belgian Institute for Postal Services and Telecommunications (BIPT), provides guidance on regulated services and consumer entitlements.

Who are the major mobile phone providers in Belgium, and how can you contact them?

Belgium’s mobile market is served by four network operators — Proximus, Orange Belgium, Telenet, and the recently launched DIGI Belgium — alongside a selection of MVNOs. The country uses the GSM standard, with nationwide 4G coverage and rapidly expanding 5G infrastructure. Here is a summary of each operator:

Proximus — With a market share of between 40–50% at the end of 2024, Proximus is the oldest and largest mobile carrier in Belgium. Its principal advantage is coverage: it reaches both densely populated urban centres and smaller rural communities. Its prepaid offering is marketed under the Pay&Go brand. Visit www.proximus.be or call 0800 33 800.

Orange Belgium — Orange offers accessible pricing and straightforward sign-up conditions, with a particular emphasis on data-heavy packages that appeal to frequent internet users. Its network performance tends to be somewhat stronger in French-speaking Belgium, making it a popular choice for those based in Wallonia. Visit www.orange.be for current plans.

Telenet / BASE — Telenet provides mobile, broadband, and TV services and also owns the BASE mobile network, which has long been associated with attractive mobile tariffs. Telenet’s network presence is strongest in the northern part of the country, particularly Flanders. Its focus on combining fast mobile internet with home broadband and television makes it an appealing option for those seeking a single integrated package. Visit www.telenet.be or www.base.be.

DIGI Belgium — DIGI Belgium entered the market in December 2024 as the country’s fourth mobile network operator, immediately drawing attention with highly competitive pricing — including a plan offering 15 GB of mobile data for €5 per month. DIGI is currently building out its own 5G infrastructure while operating under a roaming agreement with Proximus for 4G coverage in the interim. Visit www.digi.be for the latest plans — coverage and pricing are evolving quickly and should be confirmed directly with the provider.

In addition to the four main operators, a range of MVNOs (Mobile Virtual Network Operators) offer competitive alternatives. MVNOs lease network infrastructure from the major carriers rather than operating their own. Notable examples include Mobile Vikings and Scarlet (both operating on the Proximus network), Hey! Telecom and VOO (using Orange’s infrastructure), and Lycamobile (targeting customers who make frequent international calls, using the Telenet network). These can be an appealing choice for those on tight budgets or those who place many calls abroad. Check the current offers on each MVNO’s website, as tariffs change frequently.

For impartial comparisons of mobile tariffs, the BIPT offers consumer resources at www.bipt.be. The comparison platform at www.meilleurtarif.be (available in French and Dutch) is also a useful tool for evaluating current pricing across providers.

How do I get a landline connected in Belgium?

The process for getting a landline installed in Belgium is relatively uncomplicated, though it differs slightly depending on whether the property already has an active phone line. Where no line currently exists, a physical access point will need to be installed before service can be activated. The typical steps involved are outlined below:

1. Choose your provider. Depending on your address, the main options are Proximus, Orange, VOO, and Telenet, as well as various niche or alternative operators. Your location will strongly influence which providers are accessible — Proximus serves the entire country, while Telenet is the dominant fixed-line operator in Flanders and Orange/VOO is the stronger choice in Wallonia and Brussels.
2. Check service availability at your address. Every operator’s website includes a postcode or address checker allowing you to see which technologies — DSL, cable, or fibre — are available at your specific property. If a telephone line already exists there, you can also use these tools to verify eligibility for service with your preferred operator.
3. Gather the necessary documents. You must be at least 18 years old and hold a valid form of identification. Proof of your address will also be required. Tenants typically provide a lease agreement or a recent utility bill; homeowners may use a title deed. Confirm exactly which documents your chosen provider requires before submitting your application.
4. Sign a contract. A signed agreement is required before a physical line can be installed at your home. Read the terms carefully, particularly regarding minimum contract durations — many plans lock you in for 12 or 24 months, and early termination penalties may apply.
5. Schedule installation. Your operator will either send a technician to your property or, where a line already exists, activate the service remotely. Typical activation timescales range from 3 to 10 days for cable or fibre connections, and can be longer in some cases.
6. Purchase your telephone handset. A physical handset is not provided as part of the connection service. You can buy one from electronics retailers or sometimes through your operator directly.
7. Clarify any additional charges. Equipment costs vary between providers — some include a router and decoder in the monthly fee, while others charge a separate rental. Always ask about hardware costs upfront to avoid surprises on your first bill.

Whether you own or rent your home does not significantly affect this process, but tenants are advised to check with their landlord whether any existing infrastructure such as cable sockets is already in place, as this can accelerate the connection. For regulatory matters or unresolved complaints, the BIPT is the relevant authority: www.bipt.be. Consumer disputes with operators can also be referred to the Ombudsman for Telecommunications at www.ombudsmantelecom.be.

How do I get a mobile phone SIM card or contract in Belgium?

Obtaining a mobile SIM in Belgium — whether on a pay-as-you-go or contract basis — is a well-regulated procedure. One feature that distinguishes Belgium from many other countries is that all SIM cards, including prepaid ones, must be registered using valid identification.

Belgian legislation passed in 2016 brought an end to anonymous prepaid SIM cards. Under this law, a newly purchased SIM will not be activated until the buyer’s identity has been verified. This contrasts with some jurisdictions where prepaid SIMs can be bought and used without any registration formality. In Belgium, the most straightforward approach is to complete registration in person at an operator’s retail outlet by presenting a valid identity document. Most providers will require identification, so always bring your passport when purchasing.

Getting a prepaid (pay-as-you-go) SIM:

1. Visit an operator’s shop, a supermarket such as Carrefour or Delhaize, or a newsagent. SIM cards are widely available through these channels in all major towns and cities.
2. Present a valid passport or national identity card. Belgian residency is not a prerequisite for a prepaid SIM — tourists and new arrivals without yet having an official address can purchase one immediately.
3. The operator records your details in their system. Be aware that Proximus’s self-registration process can be slow, and activation may take as long as five days. If you need service promptly, another operator such as Orange — which can typically activate a SIM in minutes at the point of sale — may be a better option.
4. Top up your balance using vouchers sold at newsagents and petrol stations, through the operator’s mobile app, or via online banking.

Getting a postpaid (monthly contract) SIM:

1. Apply in person at an operator’s store or submit your application via the operator’s website.
2. A Belgian residential address is generally required to take out a postpaid contract — this is the main practical distinction from prepaid. Newcomers who have not yet registered at their local municipality may initially find themselves confined to prepaid options.
3. Provide a valid identity document, proof of a Belgian address (such as a municipal registration certificate or utility bill), and in some cases a Belgian bank account number for setting up a direct debit.
4. Once your documents are reviewed and approved, your SIM will typically be activated within a few hours.

Compared with countries where SIM registration operates seamlessly in the background, Belgium’s mandatory identification step for prepaid cards may initially seem bureaucratic — but it is quick and simple when handled in-store. The process is broadly comparable to that in France and the Netherlands, both of which have implemented similar EU-aligned registration requirements. If you are newly arrived in Belgium and want a working mobile number from your first day, purchasing a prepaid SIM in-store is the fastest route while your official residency registration is still pending.

How do I pay my telephone bill in Belgium?

Settling your telephone bill in Belgium is a straightforward process, and both landline and mobile accounts offer a range of convenient payment options. The billing cycle and available methods follow a broadly familiar Western European pattern, though there are a couple of local characteristics worth being aware of as a newcomer.

Bills in Belgium are typically issued every two months rather than monthly, and payment is expected within 15 days of the invoice date. This bi-monthly cycle means a larger amount falls due less frequently than in countries with monthly billing, so it is worth budgeting accordingly when you first arrive.

The main payment options are:

• Direct debit (domiciliation): The most widely used method in Belgium. By completing an authorisation form, you allow your bank to deduct the outstanding amount automatically from your account on the due date. Most operators offer a small discount as an incentive to set this up, and it eliminates the risk of accidentally missing a payment deadline.
• Online banking (virement/overschrijving): Belgian online banking infrastructure is highly developed, and paying a bill via your bank’s app or web portal using the structured reference number on your invoice is quick and reliable. Belgium operates within the SEPA system, which is standard across eurozone countries.
• Bank card payment: Payments can be made by debit or credit card in person at an operator’s physical retail outlet, or in some cases through the operator’s website or customer portal.
• Prepaid top-up: For pay-as-you-go mobile accounts, credit can be added using vouchers available from newsagents and supermarkets, through the operator’s app, or directly on the operator’s website.

The specific consequences of late payment vary between operators, but in most cases a first reminder is issued shortly after the deadline, followed by a second notice before any account suspension is considered. Late payment charges may be levied. If you are experiencing financial difficulty, most operators are willing to discuss a payment arrangement. Any unresolved billing disputes can be referred to the Ombudsman for Telecommunications at www.ombudsmantelecom.be.

Are there any practical tips for using phones in Belgium as a newcomer?

Belgium’s telecommunications infrastructure is mature and well-maintained. The following tips address the most common points of uncertainty for people navigating the system for the first time.

EU roaming: As a European Union member state, Belgium falls within the EU roaming framework. This means that if you hold a SIM from another EU or EEA country, you can use it in Belgium at your home country’s standard rates — no additional roaming surcharges apply. Equally, Belgian SIM plans include the use of your allowances within the EU at no extra cost. That said, fair-use provisions are in place for extended stays, so if you are relocating to Belgium on a permanent basis, it is advisable to switch to a local Belgian SIM rather than continuing to rely on a foreign one indefinitely.

Number portability: Both landline and mobile number portability are available in Belgium, meaning you can transfer your existing Belgian number when you change operator — simply initiate the process with your new provider. This typically completes within a few business days. It is not possible, however, to transfer a number issued by a foreign network to a Belgian SIM; you will receive a new Belgian number upon signing up.

eSIMs: While physical SIM cards remain the norm in Belgium, eSIM technology is gaining traction. All three major operators — Proximus, Orange, and Telenet — support eSIM on compatible handsets as of 2025. The digital-first brand TADAAM (a Telenet subsidiary) offers unlimited mobile data at €25 per month with eSIM activation (as of 2025 — verify current pricing directly with the provider). eSIM is especially useful for newcomers who wish to activate a Belgian plan before they arrive or immediately upon landing, without needing to visit a physical shop first.

Network coverage and quality: Belgium’s mobile networks use the GSM standard with nationwide 4G coverage and expanding 5G deployment. All three principal operators completed the shutdown of their 3G networks during 2024, freeing up spectrum for faster technologies. Brussels, Antwerp, Ghent, and Liège all enjoy strong 5G coverage, and 4G serves most rural areas well, with some gaps in very isolated agricultural regions. Proximus is generally regarded as having the widest reach in the countryside, while Orange tends to deliver slightly stronger performance in Wallonia.

Language of customer service and provider websites: Belgium’s three language communities mean that operator websites and support services are typically available in Dutch, French, and sometimes German. Some provider portals are offered only in Dutch or French; a browser translation tool is an easy workaround. In practice, customer service staff at major operators — particularly those serving Brussels — can often assist in English, even if this is not formally advertised.

Bundled packages: The growing popularity of “quad play” packages — combining broadband internet, television, fixed telephony, and mobile service in a single monthly subscription — makes them well worth considering as a newcomer. Bundling services typically produces a lower combined cost than subscribing separately, and managing a single bill simplifies the administrative side of settling in.

Regulatory and consumer protection resources: The Belgian Institute for Postal Services and Telecommunications (BIPT — www.bipt.be) is the national telecoms regulator. If a complaint with a provider cannot be resolved directly, the independent Ombudsman for Telecommunications at www.ombudsmantelecom.be provides free mediation for consumers.

Frequently asked questions about telephone services in Belgium

Can I keep my foreign number when I move to Belgium?

No — porting a number from a foreign network to a Belgian SIM card is not possible. Number portability in Belgium applies only to transfers between Belgian operators. When you move to Belgium, you will be allocated a new Belgian number. In the short term, you can continue using your foreign SIM under EU roaming rules, but if you are taking up permanent residence, switching to a Belgian SIM will eventually be necessary to benefit from the best available rates.

Do I need a local address to get a SIM card in Belgium?

A Belgian address is not required to purchase a prepaid SIM — valid photo identification (a passport or national identity card) is all that is needed. For a postpaid contract, however, proof of a Belgian address is generally required, such as a municipal registration certificate or a utility bill. As a result, people who have not yet formally registered their address in Belgium are typically restricted to prepaid options during their initial period in the country.

Is it easy to find English-language customer service from Belgian telecoms providers?

Provider websites and billing correspondence are primarily presented in Dutch and French, reflecting Belgium’s official language communities. In practice, though, customer service representatives at the major operators — especially those dealing with customers in Brussels — are frequently able to help in English. If you struggle to navigate a provider’s website, using your browser’s built-in translation tool is a straightforward solution.

How long does it take to get a mobile contract activated in Belgium?

The activation timeline differs between operators. Orange can typically complete prepaid SIM activation in minutes at the point of sale in-store. Proximus’s self-registration procedure may take up to five days in some circumstances. Postpaid contracts usually become active within a few hours once the required documents have been checked and accepted. Before committing to a particular operator, it is worth asking specifically about their activation timescale.

What is the emergency number in Belgium?

The universal emergency number 112 connects callers to fire, ambulance, and police services throughout the EU. Within Belgium, the number 101 is dedicated to police emergencies specifically, while 100 is used for medical emergencies and fire services. The 112 service operates in multiple languages, including English.

Are Belgian mobile plans expensive compared to other European countries?

Historically, Belgium’s mobile data tariffs have tended to sit above the EU average. However, the December 2024 arrival of DIGI as the fourth mobile network operator — with introductory plans starting at just €5 per month for 15 GB of data (as of 2025) — has injected substantial competitive pressure into the market. Tariffs are shifting rapidly in response, so it is essential to check current pricing directly on each provider’s website rather than relying on older comparisons.

Can I use an eSIM when I arrive in Belgium?

Yes. As of 2025, all three major operators — Proximus, Orange, and Telenet — support eSIM on compatible devices. International eSIM providers also offer data-only plans that connect to Belgian networks, which can serve as a convenient interim solution for short-term arrivals. For those staying longer term, a local eSIM plan from one of the main Belgian operators tends to be more economical and includes voice calling. Consult each operator’s official website for the current list of compatible devices and available plans.

What should I do if I have a dispute with my phone provider in Belgium?

If a complaint cannot be resolved through direct contact with your provider, the independent Ombudsman for Telecommunications offers free mediation for consumers at www.ombudsmantelecom.be. This service handles disputes between individual consumers and telecoms operators operating in Belgium. For broader regulatory questions and consumer rights information, the national regulator BIPT can be consulted at www.bipt.be.
