Belgium is three travel countries in a 30,000 km² box
The country is dense — about 11.8 million people across roughly 30,000 square kilometres — and the trip pattern reflects that. You're in Brussels for a meeting on Tuesday, in Bruges for a long weekend on Friday, in Antwerp for the diamond district by Sunday. The drive from one to the other is under two hours. Connectivity that resets at a city boundary or expires after seven days makes no sense in a country you can crisscross before lunch.
Roamzy charges $1.43 per gigabyte in Belgium. That's $0.0014 per megabyte, billed in real time as your phone uses data on Belgian networks. No subscription, no expiry, no minimum bundle. One per-MB rate across 192 countries — same rate in Brussels-Sud as in Knokke.
How much will Roamzy actually cost on this trip?
Belgian travel days run 0.5–1.5 GB: Maps from Bruxelles-Midi to your hotel, the SNCB app for the InterCity to Bruges, the camera-translator on a Flemish menu, your bank app for a card payment that's contactless everywhere, video calls home. Call it 1 GB/day:
| Trip length | Roamzy ($1.43/GB) | Tourist roaming pass | Airport local SIM |
|---|---|---|---|
| 3 days | $4.30 | $15–40 | $10–25 + paperwork |
| 1 week | $10.00 | $25–60 | $15–30 + paperwork |
| 2 weeks | $20.00 | $40–100 (often two passes) | $20–35 + 30-day cap |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
An airport SIM at Brussels-Zaventem or Charleroi runs the standard Belgian flow: ID, KYC at the kiosk, a tariff priced for tourists, and roughly 30 minutes you'd rather have spent on the train into town. The eSIM is attached before the wheels touch the runway.
Where does Roamzy work in this country?
- Brussels, Antwerp, Ghent, Liège, Bruges — 5G in the centers, LTE everywhere else
- The InterCity rail — near-continuous signal end to end, brief drops in tunnel sections under the Schelde
- Brussels Metro — signal on platforms and through most of the network
- The motorway grid (E40, E19, E411) — continuous LTE
- The Ardennes and rural Wallonia — solid LTE in towns, thinning on the wooded valley roads
Belgium is small enough that you'll rarely lose signal for more than a stretch of a few minutes outside the deep Ardennes. Offline-cached maps are still worth having for a weekend in the forest.

What are Roamzy's honest limitations?
Three traps Roamzy doesn't have, because they were never built in.
- No welcome promo that bait-and-switches the second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling. One rate, full speed — first GB and the hundredth both cost $0.0014/MB.
- No auto-renewal. Balance runs out, the eSIM stops. No background charge surfacing months later.
It's not a marketing gimmick — it's an engineering decision born from indifference to gimmicks. You can't make a tariff cheaper than no fine-print and no expiry — so we don't.
What if my trip continues to other countries?
Belgium sits at a junction. Eurostar to London, Thalys to Paris and Amsterdam, ICE down to Cologne — the eSIM hands over the moment the network changes:
- France — common onward via Lille; same EU rate
- Poland — the cheap-flight network out of CRL; same per-MB billing
