Monster SMS includes conversational AI auto-reply agents out of the box. Twilio requires you to build that yourself using Autopilot or external AI APIs. That means weeks of developer time vs 20 minutes of setup.

Twilio charges in USD, adds a monthly number fee, and bills per API call. Here's what sending SMS actually costs on each platform at common Australian business volumes.
| Volume / month | Monster SMS (AUD) | Twilio (est. AUD inc. number fee) |
|---|---|---|
| 1,000 messages | $50/mo (5.0c/SMS) | ~$55–$75/mo (variable, USD conversion + number fee) |
| 5,000 messages | ~$138/mo (Pro + top-up, ~2.8c/SMS avg) | ~$130–$180/mo (volume rate + number + hosting costs) |
| 15,000 messages | $600/mo (4.0c/SMS flat) | ~$280–$400+/mo (but requires dev infrastructure costs on top) |
Twilio estimates based on ~AU$0.012–0.015/SMS (USD 0.0079 + currency) plus AU$2–5/mo number rental plus hosting/developer costs. Monster SMS pricing is fixed AUD ex GST with all features included.
Twilio migrations are usually number import plus API transition projects, so the best starting point is the guided switch flow.
Then create your account and bring your numbers across when you are ready.

"Finally a platform that doesn't require a developer. Set up our first campaign in 20 minutes."
"The pricing is transparent and the AI actually works. No nasty surprises on the bill."
Yes. Monster SMS supports Twilio number import. You can bring your existing Twilio number across so your customers see the same number they already know. The process takes a few minutes and our team can guide you through it.
No. Monster SMS is built for business owners and marketers. You can create campaigns, set up AI auto-reply agents, manage contacts, and read analytics without writing a single line of code. If you want to integrate via API, that's available too.
Compliance is built in from the start. Opt-out management is automatic on every campaign. Opted-out numbers are immediately suppressed. Monster SMS is designed specifically for the Australian regulatory environment so you're not configuring compliance yourself.
For most use cases, yes. Twilio charges in USD (adding currency risk), plus a monthly number rental fee, plus you need developer time to build and maintain your SMS workflows. Monster SMS includes everything in a single AUD subscription, with all features included at no extra charge.
You can top up any time at 6c per message (500-pack) or 5.5c per message (1,000-pack). You can also upgrade your plan mid-month. You'll never be cut off without warning.
