The BTTR mobile deals engine: smarter cellular discovery
The Australian mobile market is incredibly fragmented, with three major network owners and dozens of smaller MVNOs (Mobile Virtual Network Operators) constantly shifting their price points.
From "first three month" discounts to data-heavy SIM only deals, keeping track of the best value is a moving target. The BTTR mobile deals engine simplifies this by systematically scanning the market for the latest mobile plan deals.
Our system tracks a wide range of providers and by aggregating these offers into a single view, we help you find the best mobile plan deals without the need to manually navigate dozens of provider sites.
How we source deals
Our process is driven by the BTTR deals engine, an automated system that regularly monitors the official promotional feeds of our Australian telecommunications provider partners.
We look for significant deviations from standard plan pricing, such as cheap SIM only deals, waived activation fees, or "double data" bonuses on prepaid deals.
By focusing on active data points, our engine filters out expired offers to ensure you only see the most current mobile sim only deals available in the market.
Buying guide: What to look for in a mobile deal
Finding a cheap mobile prepaid deal is only half the battle; you also need to ensure the network coverage and features meet your lifestyle. Here are the key factors to consider when using our engine to compare sim only deals:
Understanding the networks
In Australia, all providers run on one of the three major networks. While Telstra sim only deals often come with a premium for their extensive regional reach, providers like Boost Mobile offer access to the full Telstra retail network at a lower price point. Conversely, Optus and Vodafone often offer aggressive data inclusions for metro users.
Introductory pricing vs ongoing costs
Many of the best prepaid deals involve a heavily discounted rate for the first few recharges or months. Always look at what the price will revert to after the promotional period ends.
If you are a savvy shopper, you may choose to use our engine to switch providers once your discount expires to keep your costs as low as possible.
Prepaid vs postpaid (SIM Only)
- Prepaid Deals: Best for those who want total control over their budget with no "bill shock." Look for long-expiry deals (365 days) if you want the cheapest prepaid deal over a full year.
- SIM Only (Postpaid): Usually offers higher data caps and the convenience of automatic monthly billing. Most modern mobile phone sim only deals are "no lock-in," giving you the flexibility to leave at any time.
The rise of eSIM
In 2026, eSIM deals have become the standard for quick switching. If your device is compatible, look for eSIM deals in our engine. These allow you to activate a new plan in minutes without waiting for a physical SIM card to arrive in the mail.
When to find the best mobile deals
While our engine finds new savings daily, the Australian mobile market typically sees peak promotional activity during these windows:
- EOFY (June): A major period for mobile phone plan deals as providers look to hit end-of-year targets.
- Black Friday (November): Historically the best time for Black Friday SIM-only deals, often featuring the lowest prices of the year.
- Holiday/New Year: Look for best prepaid deals and "bonus data" offers during the summer travel season.
