Key answers
- What is a grey route in SMS?
- A grey route is an SMS path that reaches recipients through international third-party hubs without formal telco agreements, bypassing per-message termination fees. Messages sent this way can arrive hours late, fail silently, or produce fabricated delivery receipts.
- What is a direct telco interconnect?
- A direct interconnect hands each message to the terminating carrier — Safaricom, Airtel Kenya, or Telkom Kenya — within milliseconds, on licensed, CA-Kenya-compliant paths. Bulkit operates exclusively through direct interconnects; no traffic is grey-routed.
- How fast should a bulk SMS arrive in Kenya?
- On direct routes, delivery to all major Kenyan networks is sub-second, with authentic delivery receipts (DLRs) tied directly to the carrier rather than simulated confirmations.
Not all SMS routes are created equal. In the competitive SMS aggregator market, many providers cut costs by routing messages through international grey routes — third-party hubs that forward traffic without formal telco agreements.
Grey routes often bypass per-message termination fees, making them attractive on paper. But the trade-offs are severe: messages may arrive hours late, fail silently, or generate fabricated delivery receipts (DLRs) that mislead your analytics.
Bulkit operates exclusively through direct interconnects with Kenya's major telcos — Safaricom, Airtel Kenya, and Telkom Kenya. This means every message is handed off to the terminating carrier within milliseconds, not routed through uncertain third-party infrastructure.
- Sub-second delivery for messages to all major Kenyan networks.
- Authentic DLRs tied directly to the carrier — not simulated confirmations.
- Zero grey route exposure — all traffic is on licensed, regulated paths.
- Safaricom alone covers 65%+ of Kenyan mobile subscribers.
- Direct interconnects ensure compliance with CA-Kenya messaging regulations.
When your business sends transactional OTPs, time-sensitive payment confirmations, or emergency alerts — delivery speed and receipt authenticity are not optional. Grey routes are a gamble that businesses cannot afford.
Bulkit's infrastructure is built around direct carrier relationships. Every message you dispatch through our platform takes the shortest, most reliable path to your recipient's inbox.
