What OTP delivery looks like in Belgium.
Latency profile, peak-hour behaviour, recommended fallback chain, and the fraud signals our firewall watches in-market.
Typical latency window
Median 2.4 s with a 95th-percentile inside 8 seconds across operator-direct binds. Two-shot delivery confirmed by DLR.
Peak-hour behaviour
Operator throughput holds steady through local business peaks; throttling kicks in only during outlier mass-send events. BroadNet load-shapes per-MNO to avoid firewall blocks.
Fallback chain
Recommended fallback: Voice OTP after 30s no-delivery. WhatsApp OTP increasingly used as a low-friction alternative.
Fraud signals we watch
SIM-swap attempts on PSD2-SCA flows, robocall-style voice OTP abuse, and number-rented OTP harvesting. PSD2 audit-trail retained for 13 months.
What you can — and can't — send.
Opt-in, opt-out, quiet hours, content restrictions, and the penalty regime for the Belgium market.
Opt-in
GDPR-compliant opt-in required. Double opt-in is the operator-preferred standard for marketing.
Opt-out
STOP keyword honoured network-wide. Opt-out is one-step and irreversible until the recipient re-consents.
Quiet hours
We have not found a regulator-published time-of-day window for promotional SMS in this market. Agree sending hours with the operator and schedule promotional sends for the recipient's local daytime; transactional traffic runs 24/7.
Content restrictions
Sender-ID brand-impersonation is policed; templates flagged against fraud heuristics. PSD2-SCA flows must use a dedicated transactional sender ID.
Regulator penalties
BIPT can fine for breaches; GDPR penalties run up to 4% of global turnover for the underlying data-processing violation.
Termination,
network by network.
The route status column shows how each operator is reached — a direct BroadNet bind or a labelled partner route. No grey-route exposure. Route grades are indicative planning guides, not live measurements.
| Operator | MCC-MNC | Route status | Grade | A2P rate (typ.) |
|---|---|---|---|---|
| Proximus | 206-01 | Direct | A+ | EUR 0.0684 |
| Orange Belgium | 206-10 | Direct | A+ | EUR 0.0664 |
| Telenet/BASE | 206-20 | Direct | A | EUR 0.0644 |
Rates shown are typical pay-as-you-go for transactional traffic. Promotional traffic is priced separately, and volume tiers reduce both. See the rate-card section below for the full ladder.
| Tier | Transactional | Promotional | Notes |
|---|---|---|---|
| Pay-as-you-go | EUR 0.064 | EUR 0.074 | List rate up to 100K messages/month |

Buyer questions about Belgium.
The questions BroadNet's sales engineers field every week from teams shipping into this market.
What's the typical sender-ID approval time with BIPT in Belgium?
Typical lead time: Free-form. BroadNet confirms the current sender-ID requirements and documents during onboarding.
Are BroadNet's routes to Belgium operator-direct?
Yes — every operator on the public coverage table is a direct A2P bind. No aggregator hops, no grey-route exposure. Route grades are indicative planning guides, not live measurements.
Can I send marketing SMS in Belgium without prior consent?
No. Verifiable opt-in is required across every market BroadNet supports, with the consent source, timestamp, and channel logged. Transactional OTP and account-level alerts are exempt from marketing-consent rules.
Which channels do you support for Belgium — SMS only, or also WhatsApp and Voice?
SMS, OTP, WhatsApp Business, and Voice OTP are all supported. RCS Business Messaging is available where the local operator has launched it. All channels run on the same contract and contact model.
Can I be billed in a currency other than EUR?
Yes — billing is available in EUR / USD. Volume tiers apply automatically from 100K messages a month.
Do I need a local-language version of my OTP for Belgium?
Not strictly required for OTP, but operators prefer the body to match the registered template. Marketing traffic should be in the local language — GDPR consent must be in a language the recipient understands.
What happens if a route to Belgium degrades?
BroadNet runs continuous DLR monitoring on every operator. If a route flaps, traffic is automatically re-shaped to the next-best operator on the same destination, and your account manager is notified with a remediation note within the hour.
Do you sign an SLA for traffic to Belgium?
Yes — traffic to this market runs under BroadNet's standard SLA: 99.99% monthly platform uptime, with service credits on enterprise contracts. Support response targets and the credit schedule are published on our Support & SLA page.
