Top eSIM Providers for Belgium
Detailed reviews of our recommended providers, starting with our featured choice.
eSIM4
Best Overall Value
eSIM4 secures the top spot for 2026, offering an unbeatable combination of reliability and price. It is widely regarded as the best eSIM for Belgium for modern travelers. Whether you are visiting for a week of chocolate tasting or a month of business, eSIM4 has a package to fit. eSIM4 connects to the BASE network in Belgium.
Coverage
In Belgium, eSIM4 plans connect through BASE, which our Belgium page names above its plan list. BASE 5G is included on these plans wherever the network offers it. BASE has a mobile network of its own in Belgium. Top-ups use the link in your activation email or the Yabb app, so a longer Belgium stay needs no second eSIM.
Activation Process
A Belgium order on esim4.com is followed by an activation email with three install options. Use its QR code, the manual setup details, or the Direct Installation link, which needs iOS 17.4 or later. eSIM4 suggests installing at home on Wi-Fi, before departure. Once in Belgium, the eSIM4 profile gets data roaming switched on, your home line keeps it off, and data switching stays disabled.
Price
The cheapest way into Belgian data on this page is eSIM4’s 7-day plan with 1 GB, at $2.98. One dollar more, $3.98, doubles the data to 2 GB over 15 days. On 30-day plans, choose 3, 5, 10 or 20 GB for $4.98 up to $18.98. Unlimited plans are there too, from $7.98 for 3 days; a week costs $19.98 and a month $69.98.

Saily
Security features
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.
Saily Belgium Plans
| Data | Duration | Price |

Airalo
Regional travel
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.
Airalo Belgium Plans
| Data | Duration | Price |
|---|---|---|
| 1 GB | 3 Days | $4.00 |
| 5 GB | 15 Days | $8.00 |
| 5 GB | 30 Days | $8.50 |

Jetpac
Short-trip plans
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.
Jetpac Belgium Plans
| Data | Duration | Price |
|---|---|---|
| 1 GB | 4 Days | $7.00 |
| 20 GB | 30 Days | $40.00 |

aloSIM
Calling credits
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.
aloSIM Belgium Plans
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 Days | $4.50 |
| 3GB | 30 Days | $8.50 |

Nomad
Large data bundles
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.
Nomad Belgium Plans
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 Days | $4.50 |
