Many IoT connectivity options in Australia are designed either for large deployments โ often involving sales-led onboarding, account setup and ongoing service charges โ or around conventional mobile plans that are not built specifically for unattended devices. Installers and small businesses connecting a handful of devices can be left between the two.
Lemon Mobile exists for that gap: straightforward, long-validity 4G data SIMs you can buy directly online โ one SIM or a small fleet โ with no contracts and no monthly SIM bills.
Buy online or ask about bulk pricing
For compatible devices and standard data requirements, there is no separate business onboarding process โ choose your plan, set the quantity you need and check out directly through the product page.
Bulk orders
Multi-SIM pricing is available for bulk orders. Email hello@lemonmobile.com.au with your device brand and model, required quantity, approximate timing and preferred plan if known. Weโll check compatibility and provide pricing.
Order ahead of your installations
The service period starts when each SIM first connects to the network โ not when you buy. This allows you to order SIMs for upcoming jobs and activate them as they are installed.
