Soprano Design review
Soprano Design is an Australian enterprise CPaaS provider whose published monthly plans for an Australia selection are priced by contact count rather than message volume. The Soprano plans page shows three AUD tiers, Business from A$25 a month for up to 500 contacts; Enterprise from A$250 a month for up to 2,500 contacts; Corporate from A$900 a month for up to 10,000 contacts, but no comparable Australian per-message SMS rate at our monthly sending volumes. A written quote is therefore needed to establish actual SMS usage costs, including whether sends, number fees and GST are included.

Not yet scored
One of 45 brands reviewed. Not in the priced comparison: publishes no Australian rate.
- ISO/IEC 27001 and SOC 2 Type II certifications across the Soprano Connect and Whispir platforms
- Claims direct connections with 15+ leading carriers, bypassing aggregator chains
- Dedicated numbers and alpha sender IDs offered
- API, email-to-SMS, two-way messaging and SMPP offered
- Contact-based monthly plans with published AUD fees do not establish a comparable per-message SMS rate at our sending volumes, so no unit price comparison can be made from the plans page alone.
- Built for enterprise and government integration rather than self-serve bulk sending
- No Australian phone line is published, and support varies by plan, from 8×5 email on Business to 24×7 email on Corporate
Where Soprano Design stands
Soprano Design is a Sydney based enterprise CPaaS vendor. Its published plans, with Australia explicitly selected, are quoted in AUD per month and defined by contact limits rather than message sends, so the Business from A$25 a month for up to 500 contacts; Enterprise from A$250 a month for up to 2,500 contacts; Corporate from A$900 a month for up to 10,000 contacts figures cannot be compared with per-message SMS pricing. No verified unit SMS rate for Australia is published at our volumes. Support tiers also differ between plans, and hours are not guaranteed without a contract.

How Soprano Design prices
Soprano Design publishes no Australian per-message rate keyed to monthly volume, so this review prints none (why we never estimate one).
Soprano pricing
The Soprano plans page, rendered with Australia explicitly selected, displays three monthly plans in AUD: Business from A$25 a month for up to 500 contacts; Enterprise from A$250 a month for up to 2,500 contacts; Corporate from A$900 a month for up to 10,000 contacts. These tiers are defined by contact limits, not message sends, so they cannot be directly compared with providers that publish per-message rates. The page does not display an Australian per-message SMS price, and whether plan fees include any sends, number fees or GST is not confirmed. A written quote is required for actual Australian SMS usage.
Soprano SMS capabilities
The Soprano SMS page, as published by the provider, advertises two-way messaging with replies and keyword triggers, scheduled and event-based sends, dynamic personalisation fields, and real-time delivery reports with audit trails. The platform can be used through a no-code interface or via API, with published support for REST, HTTPS, SMPP, SMTP, SOAP, FTP and XMPP protocols. Soprano also claims direct connections with multiple carriers, described generically without naming any Australian termination carrier. Integration guidance is available in our SMS API guide.
Soprano support
The general Soprano SMS page advertises 24/7 Regional Support, but the plans page ties support to the tier purchased: email support hours increase with each plan level, and only the top tier includes 24x7 email support. These are advertised support descriptions, not contractual commitments, and no guaranteed Australian business hours are established absent a contract. Buyers should confirm severity response times, escalation paths and regional coverage in writing.
Soprano buyer fit and quote checklist
Soprano suits enterprise buyers who need multi-protocol integration, two-way messaging and tiered support, rather than small businesses wanting a self-serve rate card with transparent per-message pricing. Before committing, ask what sends are included relative to contact limits, how per-part charges and excess rates are calculated rather than assuming a blanket character threshold, what number fees apply, the billing currency and GST treatment, evidence of routing and delivery performance, API authentication and rate limits, and contracted support severity and escalation terms.
