Built for how businesses actually work
SIM‑only flexibility for small business
SIM‑only mobile plans give businesses more control and better value, without long contracts or device repayments. Choose flexible month‑to‑month plans with clear pricing — ideal if you refresh devices on your own schedule or have team members who bring their own phone.
Supporting always-on payments
Get dependable connectivity for mobile EFTPOS and other data‑first devices like tablets, kiosks and handheld scanners. For resilience, a 4G backup option helps keep essential services online during fixed‑line outages — protecting transactions, rosters and customer service when it matters most.
Coverage on the move
Keep teams connected where work takes them, with reliable 4G and 5G coverage for maps, job apps, CRM updates and video check‑ins. Share data across eligible services so heavy users get what they need, without wasting allowance — and use simple roaming packs to stay reachable when travelling, without bill shock.
Site-ready mobile
Keep supervisors and tradies connected with reliable coverage, built for real‑world site work — from calls and messaging to drawings, photos and job management apps. SIM‑only plans make it easy to use rugged or preferred devices, swap SIMs, keep numbers, and refresh hardware on your schedule. Pooled data across eligible services helps balance heavy site usage with quieter periods.
Designed for teams that flex by project
Data sharing across eligible services helps smooth usage as your team move between on‑site and office work, so unused allowance benefits the wider team. Simple plan management keeps admin light while your team stays responsive.

FAQs
Network
Vocus Mobile uses the Optus network, so your Vocus SIM connects to Optus’ national 4G and 5G mobile network.
5G is the next generation mobile network technology, offering significantly faster speeds, lower latency, and improved reliability compared to 4G . Standard 5G network uses bands N78, and requires a 4G LTE connection. When not in a 5G coverage area, compatible devices will switch to the 4G LTE network where it is available. 4G Network uses LTE bands B1, B3, B7, B28, and B40.
5G provides higher speeds, reduced lag, and better performance for demanding applications like live video conferencing, while 4G offers wide population coverage at slower speeds.
4G Backup is a 4G mobile internet connection that automatically activates if your main fixed-line connection goes down. It’s designed for fixed modems or routers capable of 4G backup and excludes mobile phones, iPads, or other mobile devices.
FAQs
Plans

5G Plans: There is no-excess-data charges, If included or shared data is exceeded, all connected services slow to 1.5Mbps until the next billing cycle unless extra data is purchased. Unused data expires at the end of each billing cycle.
