Direct A2P SMS routes for OTP and transactional traffic

Why A2P SMS routing quality decides your delivery rate

Two providers can quote the same destination at the same rate and deliver very different results, because the price says nothing about the path. A direct operator interconnect and a grey route look identical on a rate card. They stop looking identical the moment a regulator, an operator firewall or a sender-ID filter gets involved.

What actually separates them:

• Whether the receipt is real. Some routes return a delivery receipt on submission rather than on handset delivery. Your dashboard says 99%, your customers say they never got the code, and there is no way to reconcile the two.
• Whether the sender ID survives. On a compliant route your registered sender ID arrives intact. On an unauthorised one it is frequently replaced, which breaks brand recognition and, for OTP, breaks the user’s trust in the message.
• Whether the route survives volume. A path that performs at a thousand messages a day can behave very differently at a hundred thousand, particularly during local peak hours.

How we route A2P SMS traffic

Traffic is classified before it is routed. OTP and transactional messages are placed on paths selected for time-to-handset and receipt fidelity; opted-in promotional traffic is placed on paths selected for cost, within whatever the destination legally permits. Each destination carries a primary interconnect and at least one qualified standby, and degradation on the primary triggers an automatic reroute rather than a support ticket.

Compliance is part of the route, not an afterthought

Sender ID registration, DLT template approval in India, opt-in evidence, and local content restrictions are worked through during onboarding. This is slower at the start and considerably faster afterwards, because the alternative is discovering the rule when your first production campaign is filtered.
