1800 Numbers Are Free from Mobile Phones
One of the most important features of 1800 toll-free numbers is that calls are completely free for mobile phone users. Unlike 1300 numbers which cost mobile users 25-40¢ per call (or consume their plan’s standard call allowance), 1800 numbers don’t cost callers anything or use any of their included minutes.
This is particularly significant in modern Australia where mobile phones have largely replaced landlines. Most of your customers are calling from mobiles, making the toll-free nature of 1800 numbers valuable for maximizing contact. Customers don’t need to worry about call costs, whether they’re on limited mobile plans, prepaid credit, or pay-as-you-go services.

How Mobile Calls to 1800 Numbers Work
When a mobile user dials your 1800 number, their mobile network routes the call through the toll-free system at no charge to them. The call doesn’t count against their included call minutes, doesn’t consume prepaid credit, and doesn’t appear as a charge on their bill. From the caller’s perspective, it’s as if the call never happened—except they connected to your business.
This works across all Australian mobile networks including Telstra, Optus, Vodafone, and all MVNOs (mobile virtual network operators). The toll-free routing is handled at the network level, meaning there’s no special setup required for customers and no compatibility issues across different mobile providers.

While mobile callers pay nothing, your business covers the cost of calls from mobile phones. Mobile-originated calls typically cost 28-35¢ per minute depending on your plan tier—higher than the 22-28¢ per minute for landline calls, but still the same flat rate regardless of call duration or caller location.
These mobile call rates reflect the higher costs mobile networks charge for toll-free termination. Your business pays a premium to ensure mobile callers can contact you for free, but this investment often pays off through increased call volume. Mobile users are significantly more likely to call when they know it’s free, particularly for longer enquiries or support calls.
The cost difference between mobile and landline-originated calls is built into the transparent pricing structure. Higher-tier plans offer better per-minute rates for both call types. For example, the Prepaid plan charges 35¢/minute for mobile calls, while the Premium plan charges 28¢/minute—a 20% saving for high-volume operations.
Most Australian businesses find that the increased response rate from mobile advertising justifies the higher per-minute cost. When running radio ads or outdoor advertising where people primarily hear your number while mobile, offering free calling removes a significant barrier to immediate response.

Benefits of Free Mobile Calling
The free mobile calling feature of 1800 numbers provides several business advantages. First, it increases conversion rates from mobile advertising by removing cost barriers. Second, it encourages longer, more detailed enquiry calls since customers aren’t watching their credit drain. Third, it positions your business as customer-focused and accessible.
For businesses in competitive markets, offering free mobile calling can differentiate you from competitors using standard phone numbers or 1300 numbers that charge callers. Customer service operations particularly benefit—customers are more willing to call about issues or questions when they know the call won’t cost them anything.
The toll-free experience also improves customer satisfaction scores. When customers can call your support line for free and stay on the line as long as needed to resolve issues, it reduces frustration and increases positive interactions. Many businesses find this goodwill worth the additional cost per minute.
Comparing 1800 vs 1300 for Mobile Callers
The key difference between 1800 and 1300 numbers for mobile callers is cost to the customer. 1300 numbers charge mobile callers 25-40¢ per call or consume their plan’s standard call allowance. 1800 numbers are completely free with no charges or minute consumption. This difference significantly impacts calling behavior.
Research shows mobile users are substantially more likely to call toll-free numbers than charged numbers, particularly for non-urgent enquiries. They’re also willing to stay on the line longer for support or detailed information when the call is free. If maximizing mobile response is important for your business, the higher per-minute costs of 1800 numbers often deliver positive ROI through increased call volume.
However, if your business receives most calls from landlines, handles only brief transactions, or operates in low-margin industries where call costs matter significantly, 1300 numbers may be more economical. The decision depends on your specific circumstances. If you’re still deciding, consider starting with an 1800 number to test response rates, then comparing costs.
