Heading to Belgium? Here’s what to know before buying a local SIM card.
This guide covers getting a SIM card and mobile service in Belgium, whether you’re visiting for a short trip or staying longer for something like an Erasmus exchange, so you can stay connected with people back home and locally.
Can You Buy a SIM Card in Belgium?
Yes. Anyone residing in or visiting Belgium can buy a Belgian SIM card from providers like Proximus, Orange, BASE, Carrefour Mobile, Lycamobile, or Vectone Mobile.
For the best experience, make sure your phone supports the frequency bands used in Belgium and isn’t locked to your home carrier.
How to Buy a SIM Card in Belgium?
Prepaid SIM cards are available online, at some international airports, at carrier retail stores, and in some convenience stores.
Airport SIM kiosks tend to charge more and offer limited data plans, and not every airport has one, so options there can be limited. Buying directly from a carrier’s retail store usually gets you better pricing, though you’ll typically need your passport to register the SIM.
Either way, you likely won’t have service the moment you land unless you set things up in advance. If you want to be connected as soon as you arrive, an eSIM or a European prepaid SIM ordered online ahead of your trip is the simpler option.
Here’s how the plans from Base, Proximus, and Orange compare.
Proximus SIM Cards
Proximus offers a few prepaid options (check current pricing on their site, as plans change):
- Pay&go starter pack: SIM card, EUR 10 credit, and 3 GB data for EUR 5 (online offer)
- Reload 10: 500 MB data for EUR 10
- Reload 15: 3 GB data for EUR 15
- Reload 25: 5 GB data for EUR 25
If you can order online, the starter pack tends to be the best value for visitors.
Orange SIM Cards
Orange Belgium’s prepaid option is called the “Tempo Card,” with plans roughly like:
- 1 GB data, 500 texts, 31 days for EUR 10
- 5 GB data, 4,000 texts, 31 days for EUR 15
- 8 GB data, 31 days for EUR 15
- 7 GB data, 5,000 texts, 31 days for EUR 20
These tend to run slightly cheaper than Proximus for comparable data.
Base SIM Cards
Base’s prepaid options include:
- 4 GB data for EUR 15
- 8 GB data for EUR 25
Proximus tends to be the most convenient if you’re buying in person, but any of the three carriers will work fine if their store is easier to reach.
How to Buy a Belgium Prepaid SIM Card Online?
If you’d rather have a SIM ready before you land, you can order one online, including through retailers like Amazon.
Regional multi-country SIMs are also worth considering if you’re visiting more than one European country on your trip, such as the Orange Holiday Europe prepaid SIM, which covers 30+ countries including Belgium with a fixed data allowance over a set number of days. Double-check that your specific destinations are included before buying.
Another option is a prepaid European eSIM or SIM from a provider like Airalo, aimed at international travelers, with plans covering a range of data allowances, validity periods, and country counts. Compare current plans and pricing directly on the provider’s site, since these change often.
Best SIM Card in Belgium
Proximus, Orange, BASE, or an eSIM from a provider like Airalo are all solid choices for traveling in Belgium.
If you’re planning to travel to other European countries during your trip, it’s worth choosing a plan with broader regional coverage rather than a Belgium-only SIM.
Can You Use Your Phone in Belgium?
Belgium uses GSM-based mobile networks, so a CDMA-only phone won’t work there. If your phone has a SIM card slot, it supports GSM, which covers the vast majority of phones today.
Belgium, along with the rest of Europe, Africa, Asia, and Oceania (ITU Regions 1 and 3), uses one set of standard frequency bands. The Americas (ITU Region 2) use a different set of frequencies.
If your phone was bought in Europe, Africa, Asia, or Oceania, it should work in Belgium without any issues.
If your phone was bought in the Americas, it depends on the device. A high-end or recent phone almost always supports the broader multi-band coverage needed to work well abroad, including on 4G/LTE and 5G. An older or budget device might only support fewer bands, which can mean no service in some areas, or only slower 3G/2G speeds where available.
Final Thoughts on SIM Cards in Belgium
Getting a prepaid SIM or eSIM for Belgium is a straightforward process. A regional European SIM is worth the small premium if you’re island-hopping between countries, since you won’t need to swap SIMs at each border.
Proximus or BASE are reliable default choices if you’re buying a Belgian SIM specifically.
