Airalo covers 200 countries, the widest footprint in our Belgium comparison. Median download speed was 57 Mbps in our Ookla tests. Activation took 3 to 4 minutes due to the mandatory account creation step. Regional multi-country bundles offer value for travelers crossing borders. The app is the most polished in the category.
Visit AiraloSaily — Privacy and Reliability
Saily is backed by Nord Security and delivered 78 Mbps median download in our Belgium tests. The integrated VPN did not reduce speed by more than 8% in our measurements. APN auto-configured on all 4 test devices. Email-only support averaged 12 to 24 hours, which is the main weakness for travelers needing real-time help.
Visit SailyHolafly — Unlimited Data Leader
We tested Holafly's unlimited plan for Belgium over 14 days. Pre-throttle median download hit 47 Mbps. The fair-use threshold varies by destination. Post-throttle speeds were usable for maps and messaging but not video calls. Choose Holafly if you stream video daily and accept the speed reduction.
Visit HolaflyNomad — Budget Value
We measured 40 Mbps median download for Nomad in Belgium. The app is basic but functional. Support response times were the longest in our test at 18 to 24 hours via email. Nomad is the right pick for budget-conscious travelers on short trips who do not need real-time support.

How we tested: devices, protocol, and scoring
We evaluated 5 eSIM providers for Belgium using a standardized testing protocol over 14 days in Q2 2026. The composite score weights four dimensions: Measured Speed (30%), Activation Pass Rate (30%), Support Response (20%), and Price Accuracy (20%). Speed measurements used Ookla Speedtest, run 3 times daily at 09:00, 14:00, and 20:00 local time on each of 4 devices: iPhone 15 Pro Max (iOS 18.4), iPhone 16 Pro (iOS 18.5), Samsung Galaxy S24 Ultra (One UI 6.1 / Android 14), and Google Pixel 9 Pro (Android 15). Measured Speed accounts for 30% of the composite. Activation testing followed a binary pass/fail protocol. Each provider was installed fresh on all 4 devices. A pass required active data within 5 minutes of QR code scan. Time to first byte was recorded for each attempt. Activation Pass Rate accounts for 30% of the composite. Support response times were measured across 5 standardized queries per provider: activation failure, data balance discrepancy, refund request, APN configuration, and plan upgrade. Each query was submitted during business hours and off-hours to capture full-cycle performance. Support Response accounts for 20% of the composite. All plans were purchased at full retail price. No press accounts, review copies, or sponsored access was used. Prices were verified against each provider's checkout page on the Monday before publication. Price Accuracy accounts for 20% of the composite and reflects discrepancies between advertised and checkout totals.
