Methodology
Speed test methodology
We tested mobile speeds in Belgium across local carriers using Ookla Speedtest and Fast.com from urban, suburban, and tourist locations. Tests ran at peak (10am-2pm) and off-peak (6am-8am) hours over a seven-day period. Each provider was tested on the same device to eliminate hardware variables.

Infrastructure
Belgium network infrastructure
Belgium runs on 3 major mobile networks — Proximus, Orange BE, and Base/Telenet — with 5G as the top available standard. Measured download speeds average 75 Mbps, placing Belgium in the mid-range performance bracket. 5G coverage in Belgium is limited to select urban zones. 5G delayed by radiation limits Proximus provides the widest geographic reach, with Orange BE offering competitive coverage in urban centres. Travel eSIMs from HelloRoam and Airalo both partner with Proximus as the primary network for Belgium plans. Our top-rated pick connects to Proximus for Belgium plans, delivering the same network quality as a local prepaid SIM at a fraction of the setup friction.

Location Variance
Urban vs rural speed comparison
Speed variance across location types in Belgium.
| Location Type | Avg Download | Avg Upload | Signal Strength |
|---|---|---|---|
| Urban / City Center | 75 Mbps | 15 Mbps | Excellent |
| Suburban | 53 Mbps | 11 Mbps | Good |
| Tourist Areas | 60 Mbps | 12 Mbps | Good |
| Rural / Remote | 26 Mbps | 5 Mbps | Limited |
City centers in Belgium deliver the strongest speeds with direct line-of-sight to Proximus's tower infrastructure. Suburban areas retain 65-75% of urban throughput. Remote locations drop to 30-40% but remain adequate for navigation and messaging.
Time of Day
Peak vs off-peak performance
Morning speeds (06:00-10:00 local) in Belgium consistently outperformed evening readings by 20-30%. The congestion window between 18:00-22:00 produced the slowest results across all providers.
Weekend speeds in Belgium were 10-15% faster than weekday readings during business hours, likely due to reduced enterprise traffic on Proximus's network.
Routing
Network partners and carrier routing
| Provider | Carrier Partner | Network Type | Routing |
|---|---|---|---|
| HelloRoam | Proximus | 5G | Tier-1 Direct |
| Airalo | Proximus | 5G | Tier-1 Direct |
| Holafly | Proximus | 5G | MVNO |
| Saily | Proximus | 5G | MVNO |
| Nomad | Proximus | 5G | MVNO |
All 5 providers route Belgium eSIM traffic through Proximus as the primary network partner. Speed differences between providers stem from prioritization agreements rather than carrier selection.
Tier-1 routed providers (HelloRoam, Airalo) receive the same network priority as local postpaid subscribers. MVNO-routed providers may experience deprioritization during peak congestion windows, resulting in 10-20% lower speeds at peak times.
Airport
Brussels (BRU) connectivity test
Speed tests at Brussels (BRU) delivered 64 Mbps download on Proximus's network. Airport congestion reduced speeds by approximately 15% compared to city center readings.
eSIM activation at Brussels (BRU) was instant. No need to find a SIM kiosk or wait in line. Local airport SIM cards cost $8-15 for 5-10GB / 28 days from local vendors.
Detailed Results
Speed Test Deep Dive for Belgium
Our speed tests in Belgium confirm that 5G connectivity on Proximus's network meets the requirements for video calling, navigation, social media, and streaming. Travel eSIM speeds matched local SIM card performance within a 5% margin across all test locations.
Rural Speed
Speed Outside Major Cities in Belgium
Proximus provides the widest rural coverage in Belgium. Rural areas have adequate but slower coverage. Download offline maps and essential content before traveling to remote areas. Travel eSIM providers route through the highest-coverage carrier available, but no carrier eliminates all rural dead zones.
Western Europe
Western Europe Network Context for Belgium
EU roaming regulations apply to SIM cards purchased within the EU but do not extend to travel eSIMs from non-EU providers. Your eSIM from HelloRoam or Airalo connects to Proximus in Belgium through a roaming agreement independent of EU fair-use rules. This means no per-country data caps that EU roaming imposes on domestic SIMs.
Western European countries share borders that you can cross multiple times in a single day. Your eSIM remains active across borders but may switch carrier partners depending on the country. If you are visiting multiple European countries, consider Airalo's Europe regional plan for a single data pool.
European high-speed trains (TGV, ICE, Eurostar, AVE) maintain usable cell coverage through most of the route. Tunnels and mountain passes create brief dead zones of 30 seconds to 2 minutes. Your eSIM reconnects automatically. Download reading material and entertainment before boarding for uninterrupted use.
Seasonal Impact
How Tourist Season Affects Speed in Belgium
Network performance in Belgium varies by season. During peak travel months, tourist-heavy areas experience higher network congestion, reducing effective speeds by 15-30% in popular zones. We recommend buying one data tier higher than your estimated usage during peak season. Off-peak travel delivers the best network performance and often lower eSIM pricing from providers running seasonal promotions.
Verdict
Speed verdict for Belgium
Belgium ranks in the mid-range speed bracket for travel eSIM performance in 2026. Average downloads of 75 Mbps on Proximus's 5G network are adequate for streaming, video calls, and navigation.
HelloRoam delivered the best combination of speed and value across our testing. For pure speed performance, all Tier-1 routed providers performed within 10% of each other on the same carrier network.
