SMS Wholesale
A2P and P2P messaging on white routes only. Grey routes are cheaper per message and we do not sell them.
What you get
White-route delivery, end-to-end visibility.
SMS is not a commodity once a single failed OTP costs you a customer. We deliver via direct MNO interconnects and SMPP into your gateway, no third-party aggregators in the middle.
A2P messaging
Marketing, OTP, alerts, 2FA. Sender ID pre-registration per market. Throughput tuned to MNO rate limits, not assumed.
Direct MNO routes
White routes only. Direct interconnects to MNOs and SMS firewalls. Every message leaves a billing trail, not a ‘delivered, probably’ guess.
Delivery receipts
DLRs per message, not per campaign. We surface the MNO-level reject codes so your team can fix the issue, not guess at it.
Why grey routes cost more
The grey-route maths does not work the way it looks.
Grey routes exploit loopholes in the GSM framework so termination charges are side-stepped. The per-message rate is lower. The total cost is almost always higher.
01
No delivery guarantee
Grey traffic rides unverified networks. Brands often cannot tell whether a message was delivered, campaigns look like they are working when they are not.
02
MNO firewalls block it
By 2022, 82% of MNOs ran a next-gen SMS firewall capable of separating white from grey traffic. Grey gets blocked, silently.
03
Sender ID stripped
When the firewall cannot identify the source, the alphanumeric sender ID gets dropped. Your brand shows up as a random number. Open rate collapses.
04
OTP failure = churn
Two-factor authentication traffic is the largest single A2P use case. A failed OTP often means a failed signup. The per-message saving evaporates.
Market specifics
What changes by region.
SMS is local. Pre-registration, sender ID rules, throughput caps, content inspection, every market has its own playbook.
United States
10DLC mandatory
Brand registration now required or the carriers throttle throughput. We handle registration and campaign use cases end-to-end.
Europe
GDPR per country
Opt-in evidence and content rules apply per country. Sender ID pre-registration is required in most EU markets.
LATAM
Variable support
Alphanumeric sender ID supported in some markets, blocked in others. We run corridor-specific testing.
MEA
High grey pressure
Several corridors see persistent grey-route traffic. We only sell direct, selling grey costs your reputation, not just margin.
Wholesale A2P SMS is the carrying of application-to-person messages — OTPs, alerts, marketing — between platforms, aggregators and mobile operators. The craft is knowing, per destination, which route delivers with real DLRs, which route silently grey-routes your traffic, and how to protect per-message revenue in a market where the price gap between white and grey funds an entire fraud economy.
The DLR you can trust.
A delivery receipt (DLR) is only as good as its provenance. Manipulated DLRs are their own fraud category: the sender is told the message was delivered when the grey route discarded it. We track DLR integrity per route:
- Real DLRs: handset-confirmed receipts from the destination operator
- Intermediate DLRs: confirmed to the SMSC but not to the handset (labelled as such)
- Synthesised DLRs: generated by the route itself — rejected by our platform
The SMPP glossary entry covers the protocol-level details. Our platform surfaces DLR provenance per message, so you know what “delivered” actually means.
Grey route protection, built in.
Every messaging route we operate is scored against the A2P bypass observatory baselines. If your traffic starts riding P2P-priced channels, you see it in the analytics before it erodes your margin. Full methodology: the fraud guide’s messaging family.
Frequently asked
SMPP or HTTP API?
Both. SMPP for high-volume bind-based integrations; REST API for lighter workloads. DLR provenance is surfaced on both.
What is SMS pumping and how do you stop it?
SMS pumping (AIT) manufactures OTP volume toward premium ranges. We flag destination concentration with zero conversion. See the observatory for signatures.
Can I audit my current routes?
Yes — the free traffic audit covers messaging corridors as well as voice. Send your top destinations, we run the grey-route detection against your traffic pattern.
What about 10DLC, GDPR and regional compliance?
Handled per destination: 10DLC registration for US, GDPR-aligned processing for EU, sender ID registration for markets that require it. The regional variations table above covers the top corridors.
