International Messaging
A2P SMS on the corridors that matter
Application-to-person messaging delivered over direct carrier routes — with the sender ID registration, compliance handling and delivery reporting that high-volume senders depend on.

LIVE FLOWDirect SMS routes to Nigeria and West Africa
Our flagship messaging corridor: direct routes into Nigeria with the throughput and delivery rates that grey-route aggregators cannot sustain.
SMPP connectivity
Industry-standard SMPP binds with high throughput, plus HTTP API access through our CPaaS platform for lighter integrations.
Sender ID & compliance handled
Registration support per destination, DND and opt-out handling, and route transparency — so your traffic stays deliverable and compliant.
What is A2P SMS?
Application-to-person SMS is machine-generated messaging sent to end users: one-time passwords, transaction alerts, delivery updates and service notifications. Unlike person-to-person traffic, A2P lives or dies on route quality — a login OTP that arrives late is a lost customer.
Why direct routes matter
Grey routes look cheap until messages silently disappear. Direct carrier routes cost more per message and far less per delivered message. We publish delivery reporting per destination so you can see the difference in your own numbers, and we support sender ID registration in markets that require it — including the registration-heavy corridors across South Asia and Africa.
Corridors we are strongest on
- Nigeria and West Africa — direct routes, high throughput
- India, Pakistan and Bangladesh — registration and compliance support included
- Greater China — compliant routing for international senders
- 150+ further countries through quality-tested partners
Frequently asked questions
What is a grey route, and why avoid it?
A grey route delivers messages through unofficial channels — SIM farms or unapproved interconnects. It looks cheap per message, but carriers actively filter it, so delivery silently degrades. Direct routes cost more per attempt and far less per delivered message, which is the number that matters.
Do you support alphanumeric sender IDs?
Yes, where the destination market permits them. Many of our strongest corridors require sender ID registration, and we handle that registration process with you as part of onboarding.
What throughput can we expect over SMPP?
Binds are provisioned to your traffic profile — from steady transactional flows to high-burst OTP traffic. Tell us your peak TPS requirement and we will size the bind accordingly.
How does sender ID registration work in South Asia?
India, Pakistan and Bangladesh each run registration regimes with different lead times and documentation. We manage the filings per destination and keep you informed of timelines, so your traffic starts compliant and stays deliverable.
