Standard roaming charges are notoriously expensive, and finding physical SIM cards immediately upon landing isn’t always feasible.

After evaluating numerous providers, we have identified the best options to keep you connected to high-speed mobile network providers like Proximus and Orange, ensuring your trip remains seamless. Whether you need a local SIM for a short stay or a long-term solution, we’ve got you covered.

Choosing the Right eSIM for Belgium: Things to Consider

While eSIM4 is our top recommendation for an esim for travel in belgium, your specific plans might require different features. Consider these key factors when selecting your connectivity provider.

Factor Considerations Impact
Trip Length How long will you be in the country? Most providers offer durations of 7, 15, or 30 days to match your itinerary.
Network Quality Does the esim in belgium connect to strong local carriers? Look for a provider partnering with Proximus or Orange for the best rural coverage.
Data Usage Will you stream video or just use maps? Light users can survive on 1GB, while heavy streamers should look for 10GB+ plans or unlimited data.
Total Cost Is the price per gigabyte competitive? Compare the full package price against the amount of data included.
Compatibility Ensure your phone supports eSIM. Most modern phones support Dual SIM configurations, allowing you to keep your home SIM active.
Extra Features Do you need to make calls? Standard eSIMs are data-only, but some offer VoIP capabilities or a phone number.

Saily Banner

Developed by the privacy experts at Nord Security, Saily is an excellent alternative for travelers who prioritize online safety. In addition to providing affordable mobile data, the service integrates security features to protect your connection. You can download the app to make setup a breeze, even for first-time eSIM users.

Coverage

Saily lists no network for Belgium, and none of its help articles names one. Which Belgian operator the eSIM picked shows on your phone only after it connects. A trip that continues past Belgium can keep the same eSIM, because Saily loads new destinations onto it.

Activation Process

Pay on saily.com and the QR code is emailed; pay in the app and the eSIM waits in your profile for Install eSIM. Have the eSIM in place before your trip. Nothing needs pressing to start the Belgium plan; arriving does it. Your home SIM should then go off, as should mobile data switching.

Price

Saily’s Belgian plans begin with 1 GB for 7 days, at $3.99, already $1.01 above eSIM4. The gap grows with plan size, up to $7.01 on the 20 GB month, which costs $25.99. Saily’s shortest unlimited plan, 5 days at $18.99, costs more than any rival’s first unlimited plan here; 30 days cost $71.99.

Airalo Banner

As one of the pioneers in the eSIM market, Airalo remains a solid choice, particularly for those planning a multi-country European Union tour. Their local plans for Belgium connect to the Telenet network. If you are crossing borders, their regional and global “Eurolink” packages covering multiple European countries are very convenient.

Coverage

On Airalo’s Belgium page, the named network is Telenet, with 5G available on these plans wherever Telenet has rolled it out. Telenet is a well-known name in Belgian telecoms. Before paying, follow the page’s link to the full list of networks the eSIM may join.

Activation Process

Most Airalo packages for Belgium sit idle until the eSIM makes its first connection there. Others start at installation, as the Activation Policy shows. Start installation, in the Airalo app, puts the eSIM straight onto an iPhone or certain Android models. In Belgium, switch data to the eSIM line and copy the roaming setting Airalo’s app shows.

Price

Light users can start with Airalo’s $4.00 plan, which covers 3 days and 1 GB. Airalo wants $8.50 for a 30-day plan with 5 GB, so eSIM4’s same plan saves $1.52. Unlimited is $9.50 on the shortest, 3-day plan and $71.50 on the 30-day one. Calls come only on separate data-and-calls plans, which begin at $5.50.

Jetpac plans start at $7.00 for 1GB over 4 days, with 1-day passes from $8.50 for 3GB. While basic, it is perfect for quick trips or emergency data access.

Coverage

Proximus, KPN Group and Mobistar are the Belgian names in Jetpac’s help-centre network table, dated January 2025. Jetpac says the list is for packs it sold after 12 September 2024. Run out of data on a 3 GB or bigger pack, and essential apps like WhatsApp and Google Maps still work for free.

Activation Process

Bought from Jetpac’s app or website, a Belgium pack keeps for up to 3 months unused. To install, pick the app, Jetpac’s QR code email or hand-typed SM-DP+ details. Hold off switching it on until the plane lands in Belgium. It then needs data roaming, but Allow Mobile Data Switching should never be turned on.

Price

On price per GB, Jetpac ranks last here; even its 10 GB, 1-day pass works out to $1.45. Jetpac’s $40.00 for a 20 GB month is over twice eSIM4’s price, a $21.02 gap. Unlimited passes run $15.00 for 3 days and $37.00 for a week; that week costs $17.02 more at Jetpac than at eSIM4.

aloSIM Banner

aloSIM differentiates itself by addressing the need for voice communication. While the eSIM itself covers data needs, they offer a companion app (Hushed) that provides a temporary phone number for calls and texts. Plans often include a small credit to get you started, which is useful for booking restaurants or calling hotels.

Coverage

KPN, Orange and Proximus are listed as current networks on aloSIM’s Belgium destination page, which you can read before buying. Later, the same three appear among the eSIM features in aloSIM’s app. With three listed, the eSIM has more than one network it can use.

Activation Process

Of three install methods under My eSIMs in its app, aloSIM rates automatic install fastest, ahead of a QR code or manual entry. Package days stay frozen until a supported Belgian network picks up the eSIM. Settings wait for travel day, when the eSIM becomes your cellular data line with roaming on and alosim as its APN.

Price

At $3.50, aloSIM’s Belgium range starts with 1 GB for a single day. Need 5 GB for a month? That is $11.00 at aloSIM and $4.02 less at eSIM4. Bought as 50 GB for 10 days at $25.00, data costs $0.50 per GB, less than anywhere else here. No rival here starts unlimited below aloSIM’s $5.00 one-day plan.

For travelers who need flexibility or larger data packs, Nomad is a strong contender. They offer a variety of plans that cater to both short trips and longer digital nomad stays. Their app is clean and easy to navigate, and they partner with Proximus and Orange Belgium.

Coverage

Proximus and Orange Belgium carry Nomad’s Belgium plans, going by the Network for Belgium line on Nomad’s site. Where either network has 5G, these plans can connect to it. Both are big names in Belgian mobile phone service. The same pair is listed under Network in the app’s Plan Details, so you can check after buying.

Activation Process

Scanning the QR code from your order email is Nomad’s preferred install, and it is best done at home before the trip. The app or manual codes are other options. Leave the eSIM off until Belgium. Once there, it must carry mobile data and have roaming on, and a restart completes the setup.

Price

Across the Belgium plans both sell, Nomad’s prices run $1.02 to $5.52 above eSIM4’s. Its 20 GB month comes closest, at $20.00. Nomad has no plan under $4.50 here; that price buys 1 GB for 7 days. For unlimited data, Nomad sells nothing past 10 days, which costs $33.00, while 3 days cost $11.00.

How To Make Phone Calls with Your eSIM

Most travel eSIM providers offer data-only plans. Here are your options for making calls while in Belgium:

Internet-Based Apps

You can use apps like WhatsApp, FaceTime, or Skype over your esim for data connection. These are excellent for calling other app users, though you generally cannot reach local landlines or businesses without credits.

Voice-Enabled eSIMs

Some providers offer eSIMs with a dedicated phone number, but these often come at a premium. You will need to manage Dual SIM settings and share a new foreign number with your contacts.

Using Yabb with Your eSIM

The Yabb app is designed to work seamlessly with your data plan. Simply download it to access these features:

  • Call landlines or mobile numbers in Belgium or globally
  • Contact local hotels and restaurants for reservations
  • Prepay as you go with no contracts
  • Enjoy clear voice quality using your internet connection

Why Use an eSIM in Belgium?

Purchasing a physical SIM card in Belgium can be time-consuming, often requiring you to visit a shop and present an identity document for verification.

The eSIM advantage: Digital SIMs allow you to bypass these hurdles completely. Since you are roaming on partner networks, there is typically no need for complex identity verification for data plans. You simply scan, activate, and connect as soon as you arrive at Brussels Airport. It is a secure and efficient way to handle your connectivity needs.
