Cellcast is an Australian-owned SMS and MMS platform based in Melbourne. It offers an SMS API gateway, email to SMS, two-way messaging and a shared inbox, and its Cellcast Infinity plans add reviews, marketing tools and AI agents.
Pay as you go in Australian dollars, with credits that never expire: from about A$0.047 per SMS on the smallest bundle down to A$0.028 at volume, and MMS from A$0.18 to A$0.34. Replies are free. Infinity plans cost A$87, A$159 or A$587 a month with 500, 2,000 or 4,000 SMS credits. Dedicated numbers are a paid add-on.
Cellcast has no iMessage or RCS, so iPhone users get SMS or MMS. Linq sends iMessage with RCS and SMS fallback from real phone numbers for a flat fee from $260 a month with no per-message fees, while Cellcast bills per message. Both offer an API with inbound messages; Cellcast also sells marketing and review tools.
Australian businesses that want low-cost bulk and two-way SMS, with an inbox and AI agents for leads and reviews.
