A2P SMS and bulk SMS on carrier routes.

A2P SMS (application-to-person) is the traffic businesses send to people: one-time codes, delivery windows, appointment reminders, statements and campaigns. On PacketExchange it runs on SMS routes bought direct from the carriers who list them, at the route's own rate per segment, with each route's tier and sender support stated before you buy.

Bulk SMS needs no separate product: one request reaches one number or up to 1,000, and every message gets its own ID and status. Send from your brand as an alphanumeric sender, or from a number, and numbers on your do-not-contact list are refused before routing, so a suppressed send costs nothing.

  • Up to 1,000 recipients in one bulk request, with a status per message
  • Alphanumeric, numeric or pre-registered senders, stated on every SMS route
  • One-time codes by SMS, or by a call that reads them aloud, with no verification fee
  • Segments counted before sending: 160 GSM-7 or 70 Unicode characters in one

The SMS APISMS on PacketExchange

Send from the SMS API, or bind over SMPP.

Applications post one JSON request per message to the SMS API. Messaging platforms that already speak SMPP bind straight in: every SMS route you buy comes with its own system ID and password, and messages submitted over the bind are billed on the same segment and fee rules as an API send. Leave out the route and Smart Routing picks the cheapest, the best quality or a balance of both for each destination, or name the route you bought.

SMS pricing and wholesale SMS routes.

An SMS costs the route's rate multiplied by its segments, plus a platform fee of 2% of that amount, capped at $0.001 per message. It is worked out before the message leaves and returned in every reply, and a refused message is reversed in full. Top up from $5 by card or crypto, with no monthly fee and no minimum volume.

Frequently asked questions

What is A2P SMS?
Application-to-person messaging: messages a business sends from its software to people, such as one-time codes, alerts, reminders and campaigns. On PacketExchange it runs on SMS routes bought direct from carriers, at the route's own rate per segment.
Can I send bulk SMS?
Yes. One API request can carry up to 1,000 recipients, and every message in it gets its own ID and status. Platforms that send at volume can also bind over SMPP with the credentials issued with each SMS route.
How much does an SMS cost?
The route's rate for the destination multiplied by the number of segments, plus a platform fee of 2% of that amount, capped at $0.001 per message. The cost is calculated before sending and returned in the reply.
Can I use my brand name as the sender?
Yes, on routes that carry it. Every SMS route lists whether it carries alphanumeric, numeric or pre-registered senders.
Do you support SMPP?
Yes. Every SMS route you buy comes with its own SMPP system ID and password, and the bind is metered to the throughput the route carries.
Can I send OTP and verification codes?
Yes. Send one-time codes by SMS, or by a call that reads them aloud, with no verification fee.
