The short version

  • Only Courier has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bandwidth commercial terms are negotiated contracts rather than a published rate, so a small team cannot start without going through a sales process.; Courier enterprise-only features like RBAC and EU data residency require a custom sales conversation rather than a published plan.
  • They diverge on capability: Bandwidth covers Owned US carrier network, Courier covers Multi-channel sending.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bandwidth

  • Commercial terms are negotiated contracts rather than a published rate, so a small team cannot start without going through a sales process.
  • US A2P messaging still requires 10DLC brand and campaign registration, and those fees plus per-segment carrier surcharges are charged on top of the negotiated message rate.
  • The self-serve developer experience is weaker than the aggregators it competes with, so teams prototyping quickly start elsewhere and migrate later, if ever.
  • Its owned-network advantage is a United States advantage; international coverage arrived through the Voxbone acquisition and does not rest on the same model.
  • Committed volume pricing means an organisation whose traffic falls short of forecast pays for capacity it did not use.

Courier

  • Enterprise-only features like RBAC and EU data residency require a custom sales conversation rather than a published plan.
  • Pay-as-you-go per-send pricing on Business can become costly at very high volume compared to flat committed pricing elsewhere.
  • The free Developer tier is capped at 10,000 sends per month, which is limiting for growing production apps.

Answered from the vendors’ own pages

Bandwidth: Is Bandwidth a carrier or a reseller?

It is a licensed carrier operating its own US network. That removes the wholesale margin an aggregator pays its upstream and gives direct control over routing and regulatory functions such as E911.

Courier: What does Courier cost?

Courier has three plans: Developer is free for 10,000 sends per month, Business is pay-as-you-go at $0.005 per send, and Enterprise is custom-priced with volume discounts.

Bandwidth: Do 10DLC fees apply on top of Bandwidth's rates?

Yes. US A2P messaging requires brand and campaign registration with The Campaign Registry, and the registration fees plus per-message carrier surcharges are billed in addition to whatever per-message rate you negotiated.

Courier: Is there a free plan, and what are its limits?

Yes, the Developer plan is free and includes 10,000 notification sends per month along with journeys, broadcasts, the MCP server, CLI, SDKs, and email support.

Source
Bandwidth: Did Bandwidth acquire Voxbone?

Yes, in 2020, for 519.4 million dollars. Voxbone supplied international phone numbering and became the basis of Bandwidth's coverage outside the United States.

Courier: How is usage metered?

Courier bills based on the number of notifications sent, not on team size or number of channels used, with Business plan sends charged at $0.005 each.
