  • IoT SIM Cards for Small Businesses & Installers

Many IoT connectivity options in Australia are designed either for large deployments β€” often involving sales-led onboarding, account setup and ongoing service charges β€” 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 β€” one SIM or a small fleet β€” 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 β€” 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. We’ll check compatibility and provide pricing.

Order ahead of your installations

The service period starts when each SIM first connects to the network β€” not when you buy. This allows you to order SIMs for upcoming jobs and activate them as they are installed.

When this isn't the right fit

This is a physical 4G data-only SIM service. It may not be suitable if your device or project requires:

  • LTE-M, Cat-M1 or NB-IoT connectivity
  • Voice calling or regular SMS operation
  • A 2G or 3G-only connection
  • Devices that require a manufacturer-supplied SIM or embedded eSIM
  • High-data mobile broadband or continuous video streaming

Customer Reviews

Overall rating: 4.9 / 5 from 469 reviews.

Fantastic product. So easy to use and delivery was quicker than stated. And I have to give a huge shout out to the great customer service, as my teen daughter was using this card while in France on student exchange and initially became unsure how to activate it properly, but a quick email to customer service and a reply within the hour had her up and running... She just had to turn her phone off then on again πŸ˜†.
