How to Choose a Mobile Carrier in Australia Based on Coverage and Price

Check the predicted coverage at your home your workplace and your regular travel locations first. Then compare the price the data, the renewal periods the 4G and 5G access, the speed limits and the essential features. Network reliability is specific, to each location so use maps and practical testing instead of only relying on national coverage claim.

ACMA's guidance also recommends checking coverage, costs, features and whether your device will work with the service before choosing a mobile provider.

A mobile carrier can have broad coverage across Australia and still not be the right choice for your particular locations.

Start with the places where you use your phone most:

• Home: Check coverage inside and around your home, particularly if you make calls indoors.

• Work: If you work in an office, warehouse, shop or other building, check the coverage around that location.

• Commute: Look at the areas you travel through regularly.

• Regional and rural travel: If you regularly travel outside major cities, check the exact towns and roads you use.

• Frequent destinations: Include places such as a family member's home, holiday property or regular camping location.

Australian mobile coverage maps are based on predictive modelling. They are useful for comparing networks, but they cannot guarantee the exact service you will receive at every location.

ACMA's standardised mobile coverage rules took effect from 30 June 2026. Mobile network operators must now publish 4G and 5G coverage maps using the standard categories good, moderate, basic and no coverage, with plain-English descriptions. The maps must also be updated at least every three months.

Even a location marked as having good coverage can perform differently indoors or during busy periods. Buildings, hills, vegetation, distance from a tower, device compatibility, network congestion and maintenance can all affect your experience. ACMA's new rules are designed to make coverage easier to compare, not to guarantee a particular result.

You can compare the official coverage maps from the major network operators, including Telstra's coverage map and Optus' coverage map.

There is no single coverage category that works for everyone. 

If you mainly use your phone in a metropolitan area, good or moderate coverage at your key locations may be enough for everyday calls, messages and data.

If you regularly travel through regional or remote areas, it can be more important to check the specific locations you visit rather than looking at an overall national coverage figure.

If your home has thick walls, a basement or other areas where mobile signals struggle, also check whether the plan supports features such as Wi-Fi Calling. This can help with calls when a compatible phone is connected to Wi-Fi.

Australia has three major mobile network operators: Telstra, Optus and TPG Telecom. Many other mobile providers operate as Mobile Virtual Network Operators, or MVNOs, using access to one of these networks. ACMA explains that many phone companies use the networks of Australia's major operators.

This means you should not judge a mobile provider only by its brand name.

When comparing an MVNO, check:

1. Which underlying network it uses.

2. Which parts of that network are available to its customers.

3. Whether the plan includes 4G, 5G or both.

4. Whether there are speed limits.

5. Whether features such as VoLTE or Wi-Fi Calling are supported.

6. Whether your phone is compatible.

Two providers using the same underlying network can still offer different plans, pricing, speed limits and features.

The easiest way to confirm the details is to check the provider's coverage page and CIS.

The price shown on an advertisement is not always the price you will pay long term.

Before choosing a plan, look at:

• introductory or promotional pricing

• the standard price after the offer ends

• how often the plan renews

• data included

• excess data charges or speed reductions

• optional extras

• international calls or roaming costs

• any activation or other fees.

ACMA requires telecommunications providers to provide a Critical Information Summary (CIS) for their products and plans. A CIS sets out important information such as inclusions, exclusions, fees, contract terms and other conditions.

More data is not automatically better value.

Think about what you actually do on your phone. Someone who mainly sends messages, checks email and browses the web may need much less data than someone who regularly streams video or uses their phone as a hotspot.

A simple way to estimate your needs is to check your recent mobile usage.

You could group your usage like this:

If you consistently use 15GB each month, a plan with 100GB may not give you much practical benefit unless you expect your usage to increase.

Also check what happens after you use your included data. Some providers charge for additional data, while others reduce the available speed.

Once coverage, price and data look suitable, check the smaller details.

Useful features can include:

• eSIM support if you want to activate without a physical SIM 

• VoLTE for compatible voice calls

• Wi-Fi Calling for calls in areas where indoor mobile coverage is weaker

• International roaming if you travel overseas

• International calls if you regularly contact people outside Australia

• Data rollover if available and useful for your usage

• Usage alerts to help monitor your data

• No lock-in contract if you want more flexibility

• Prepaid billing if you prefer to pay upfront.

You should also confirm that your existing phone is compatible before switching. ACMA advises consumers to check whether their device will work with the new telco's network.

For eSIM users, check that your particular phone supports eSIM and that the provider allows eSIM activation for the service you want.

Yomojo is one option for customers looking for prepaid mobile service with 30-day renewals and no lock-in contracts.

Current Yomojo prepaid plans include unlimited standard national calls, SMS and MMS, with different data allowances. As checked on 17 September 2026, the available plans include:

Yomojo services use the Optus network. The current Yomojo plan pages list Optus 4G with speeds of up to 150Mbps, along with Wi-Fi Calling, VoLTE and eSIM support on compatible services and devices.

Coverage should still be checked for your own address and regular travel locations. Yomojo's coverage map provides expected Optus coverage, while noting that actual performance can vary because of buildings, terrain, network demand, device compatibility and other factors.

You can check Yomojo coverage before choosing a plan.

Choosing a mobile carrier in Australia comes down to more than finding the cheapest plan.

Start with coverage, especially at home, work and the places you travel regularly. Then compare the ongoing price, renewal period, data allowance, network access, speed limits and features.

A plan that looks cheaper at first may cost more over a year if it renews more frequently or has a large price increase after a promotion. Likewise, a plan with more data is not necessarily better value if you rarely use it.

Use official coverage maps, check the provider's CIS and compare plans using the same set of criteria. That gives you a clearer picture of what you are actually paying for and whether the service fits the way you use your phone.
