Cellcast sells fixed prepaid credit bundles rather than pricing on monthly volume, so every rate here is the cheapest published combination of bundles that covers the month: 3.7c at 1,000, 3.1c at 15,000 and 2.83c at both 125,000 and 250,000. Mobile Message publishes 3.5c and 3.0c at the lower two volumes and 2.5c at the upper two, so Cellcast is second cheapest in Australian dollars at all four rather than cheapest at any, which several older pages on this site still say it is. Above 100,000 messages a month Cellcast asks you to contact it for a quote, so a large sender may do better than the published figure. Shared numbers and replies are free and credits never expire. Its two absolute claims, a 100% uptime SLA and a 100% delivery guarantee, are published without any supporting document, and its pricing page advertises a lowest-price rating attributed to this site while deep-linking our own comparison table.

Cellcast stands out as the top choice for SMS reminder services in Australia, primarily due to its user-friendly platform that simplifies creating, saving, and modifying message templates. This feature is a significant factor in its recommendation as the go-to SMS reminder provider.
The platform’s intuitive interface ensures ease of use, and its capability for immediate customer response streamlines the process of dispatching crucial, timely SMS reminders. This efficiency is particularly valuable across various industries, where timely reminders can enhance operational efficiency and customer engagement.
SMS Comparison has identified several compelling reasons to opt for Cellcast for your SMS reminder needs, highlighting its value proposition:
The service enables effortless text message sending directly from your personal or business email, their API, or Web SMS platform, making it versatile for different user preferences.
The availability of saved templates facilitates the regular dispatch of SMS reminders, enhancing consistency and reliability in communication.
It allows for the personalization of messages, automatically incorporating your customers’ names and adding a touch of personal engagement to each reminder.
Support is readily available through live chat and phone, ensuring users can access professional help whenever needed. This enhances the overall user experience and service reliability.
With postage costs rising and emails rapidly filling your computer system, SMS reminders quickly become a favoured choice for large, medium and small-sized businesses and organisations across Australia.
With immediate cut-through and a high return on investment, SMS as an effective reminder system can save your organisation significant money and time. Still, it can open up a two-way dialogue with your customers if required. Those enterprises that rely on regular customer and client appointments will know and appreciate the pain caused by regular no-shows. A well-designed SMS reminder program can allow you to set and forget, ensuring your SMS are delivered to those scheduled for an appointment that day, week or month – or most notably, when it matters most for your business.
Not only do organisations save on their postage costs, but they also free up valuable staff time by alleviating the arduous task of multiple reminder phone calls. SMS reminders mean fewer phone calls, happier staff, and a more productive office.

Every provider on this page is scored out of 10 on one method, applied the same way to all of them: published price at four volume tiers, sender and number options, sending methods, stated carrier routes, uptime terms and support cover.
We do not open accounts and we do not send test traffic. Every figure here comes from a page the provider or a named third party publishes, and the date it was read is on the review it came from. Where a provider publishes nothing for a field, this page leaves it blank rather than filling it in. A provider we have not yet scored is shown without a score rather than with a low one.
