This is the same information you'll get before you sign anything.
Ask five wholesale providers for pricing and you'll get five versions of the same sentence: "discounts as you scale." Here's what that sentence usually hides — and what you get here instead.
| Industry default | TrunkLine | |
|---|---|---|
| Volume pricing | A vague promise, with numbers behind a sales call | Published graduated tiers, before you sign anything |
| Margin | Bundled into one rate — impossible to audit | Shown as its own line, separate from carrier passthrough |
| Route quality | You hear about problems from your own customers | Every CDR is visible the moment it lands |
| Growth pricing | Rewards whoever is already biggest | Rewards growth against your own baseline |
| Inbound traffic | A pure cost line on numbers you already own | A revenue line, if you want it to be |
Rates step down in graduated bands as your monthly volume grows. Crossing into a new tier only changes the price of the segments in that tier — never the ones you already sent.
| Monthly segments | Rate per segment |
|---|---|
| First 1,000,000 | $0.0080 |
| Next 5,000,000 | $0.0065 |
| Next 20,000,000 | $0.0050 |
| 25,000,001+ | Custom |
Volume-tier pricing re-prices messages you already sent once you cross a threshold — which means invoices that quietly change after the fact. Graduated tiers price each segment at the rate for the band it falls in, permanently. You can reconcile every invoice against your own logs, every time.
If your deal genuinely needs a committed-volume structure, we handle the shortfall as one explicit true-up line at period close — never as a silent re-rating pass over messages you've already been billed for.
Six things that are usually a negotiation elsewhere, published here as a default.
Passthrough and margin are billed separately, so you can see exactly what the carrier charges and what we charge, on every invoice.
Rebates are calculated against your own prior-period volume, not a flat table that only rewards whoever is already biggest.
Host, port, bind sessions and throughput are documented before you sign anything, not revealed after onboarding.
Every message is browsable in real time, so a delivery problem shows up on your dashboard before it shows up in a support ticket.
Own a number range? Two-way and inbound traffic can be turned into a revenue line instead of sitting on your books as pure cost.
A white-label console with your branding, your sub-accounts and your own markup, running on our infrastructure.
No discovery call required to get started — just the information we'd ask for on one anyway.
Destinations, volume and sender types — about ten minutes.
Graduated pricing and route options land in your inbox, not a meeting invite.
Send real volume on a small batch and check delivery and DLR quality first.
A named person who knows your account, not a rotating support queue.
"We could finally hand our finance team a rate card without translating it for them first."
Name, Title, Company"Pilot batch landed clean DLRs within a day. That's rare in this market."
Name, Title, CompanySend a traffic profile and get a rate card back. No call required to get the numbers — though we're glad to have one after.
This goes to a real person, not a queue. We'll reply within one business day with route options and a rate card built around what you actually send.
No. Most accounts start with a pilot batch on a small volume, then scale once delivery and pricing check out.
SMPP 3.4 (transmitter, receiver and transceiver binds) and a REST API. Host, port, bind sessions and throughput are documented during onboarding, before you commit to anything.
Both are available — we'll recommend one based on your traffic profile and history.
Yes. If you own number ranges, inbound traffic can be set up as a monetized two-way program rather than a pure cost line.
Yes — the white-label console supports your own branding, sub-accounts and markup on top of our infrastructure.
Most accounts are sending a pilot batch within a few business days of sending a traffic profile.
