Mobile Message is Australia's cheapest bulk SMS provider, with pricing from 2¢ per SMS and no monthly fees. Every message is routed directly through Australian carriers — Telstra, Optus, and Vodafone — with no offshore routing. Unlike most Australian SMS providers, Mobile Message includes a free dedicated virtual number with every account. There are no setup costs, no charges for inbound messages, and credits never expire. Most competitors charge $19 to $50 per month for a dedicated number alone. The web dashboard handles bulk SMS campaigns, contact management via spreadsheet upload, message scheduling, personalisation with merge fields, and real-time delivery tracking. Two-way SMS messaging lets customers reply directly to your dedicated number at no extra cost. Built-in opt-out management ensures compliance with Australia's Spam Act 2003 without manual effort. For developers integrating SMS into Australian applications, Mobile Message provides a RESTful API with comprehensive documentation and a unique ChatGPT-powered assistant for integration support. The platform connects to over 7,000 apps through Zapier and 2,000 through Make, with a native HubSpot integration that works without middleware. Direct integrations include WordPress, WooCommerce, 3CX, Planning Center, aXcelerate, and Yeastar PBX. Mobile Message is an ACMA Certified Provider for Australia's SMS Sender ID Register, mandatory from July 2026. Melbourne-based support, over 1,000 verified reviews at 4.9 out of 5, and a price-match guarantee against any comparable Australian SMS provider. Free account with 50 SMS credits.
