Why choose a SIPcity mobile number?

  • Reach customers where they actually are. Australians know and trust mobile numbers. Using a 04 number makes your messages feel personal and local. Perfect for appointment reminders, confirmations, and two-way customer conversations.
  • Send and receive SMS in one place. Unlike standard landline or VoIP numbers, mobile numbers are the only type that support SMS in Australia. With SIPcity, you can send and receive texts straight from your SIPcity apps, no personal phone required.
  • Shared SMS for your team. Create a shared inbox experience with Shared SMS. Multiple team members can read, reply, and manage texts from a single customer-facing mobile number, keeping communication seamless and consistent.
  • Built for business. A SIPcity mobile number helps unify all your channels — calls, messages, and collaboration — under one reliable Australian network with no overseas routing or lag.

Share a mobile number with your team.

One of the most powerful features of SIPcity mobile numbers is Shared SMS. Your entire team can access the same customer-facing 04 number, with everyone able to view conversation history and send replies. This means your customer always sees a consistent phone number, whilst behind the scenes, any available team member can respond.

It’s perfect for customer service teams, sales departments, or any business where multiple people need to handle SMS conversations. No more forwarding messages or wondering who responded to what—everyone stays in the loop.
