Canstar Blue’s annual review of postpaid SIM-only providers compares Telstra, Optus, Vodafone, Southern Phone, Belong, Vaya, iiNet and Dodo based on value for money, customer service, network coverage, ease of sign up & activation, billing, plan flexibility and overall satisfaction.
See our Ratings Methodology.
Southern Phone is the winner of Canstar Blue’s customer satisfaction award for SIM-only postpaid plan providers, scoring five-star reviews on billing, customer service, value for money and overall satisfaction.
To find the best phone plan for your needs, you’ll first need to determine which type of phone plan you want. If you desire the perfect trade-off between flexibility and value, then a postpaid SIM-only phone plan may be the way to go. Provided you already own your own handset, you can pick from more than 20 different mobile carriers, all desperate for your business. Activating a new plan is as easy as ordering a SIM and porting over your old number if you want to keep it. But with so many service providers to choose from, picking the right plan for your needs represents a challenge.
Canstar Blue can offer a helping hand with our annual review of postpaid SIM-only providers and their plans. Each year, we survey thousands of mobile users across Australia to find out how they’re getting on with their phone plans, and ask them to rate their mobile service providers based on key factors, including the sign up and activation process, customer service, billing information, network coverage, plan flexibility, value for money and overall satisfaction. While the majority of postpaid SIM-only plans come on no-contract terms, these ratings also include feedback from customers on contracted SIM-only plans. These are not to be confused with mobile phone plans that include a new handset.
This year’s review sees the big guys – Vodafone, Optus and Telstra – pitted against smaller providers Southern Phone, Belong, Vaya, Dodo and iiNet. You might not have heard of all five lesser-known telcos, but this year’s results make a compelling case for taking a chance outside of the big three networks. So, what did we find this year?
Here are he best providers for postpaid phone plans, as rated by customers in Canstar Blue’s latest review:
Southern Phone makes its SIM-only postpaid ratings debut with an overall satisfaction score of five stars, seeing it take out the top spot for 2019. Another new entrant, Belong landed in second place with an overall score of four stars. It also achieved a five-star rating for its network coverage. Vaya rounds out the top three for 2019, scoring four stars for overall satisfaction.
It wasn’t a good year for the biggest three providers when it comes to their postpaid SIM-only plans, with Vodafone, Optus and Telstra holding up the rest. However, you shouldn’t be entirely put off by this result as customers of the big three providers tend to rank their service lower, but they can still offer a great deal.
Our annual review provides an insight into what customers think of these postpaid plan providers, but what exactly do they have to offer you right now? Read on as we compare plans from the eight providers in our review and provide a guide on what you should look for from a great postpaid plan.

You might not be familiar with Southern Phone, but the community-focused telco has been around since 2002. With a focus on supporting customers in regional and remote Australia, Southern Phone offers a comprehensive range of phone and broadband plans, including its great-value SIM-only postpaid options.
Operating on the Optus 3G and 4G networks, Southern Phone’s bring-your-own-phone plans are available on both 12-month and no-lock-in contracts, with prices beginning from just $9 per month for 1GB of data. With all plans priced at $60 per month or less, Southern Phone’s postpaid range makes for an affordable alternative to big-name providers, and all plans include unlimited standard talk and text to Australian numbers. If you’re looking for a SIM-only plan with good value data and no unwanted extras, these plans offer simplicity, easy sign-up, and no fuss.
Data options are available up to 80GB per month; this should be more than plenty for most Australian phone users, as well as serious streamers and downloaders. In addition, Southern Phone’s excellent ratings for customer service, plus its 30-day network guarantee, may be enough to for many value-conscious customers to give the telco a try.

Another simple, drama-free SIM-only provider, Belong operates on Telstra’s 3G and 4G networks, covering more than 97% of the population. Its postpaid plan suite currently offers just two basic plans: 10GB for $25 per month, and 40GB for $40 per month. All plans are available on a monthly basis.
While Belong’s range is small, it’s affordably priced, with all plans including unlimited standard calls and texts in Australia. If you opt for the $40 plan, you’ll also get unlimited standard international calls and texts to selected countries – an option available on smaller plans for an additional $5 each month. All three plans also feature unlimited data banking, meaning you can save any unused gigabytes each month for future use.

Another internet-focused telco with a side hustle in mobile, Dodo’s simple SIM-only plans are available on month-to-month terms. There is also a no-data plan available for a tiny $5 per month with optional data, international call and MMS add ons available.
Plans are priced from $5 per month for no data (but with an optional 2GB of data to add on for an additional monthly $10), and all feature unlimited national talk & text in Australia. The $20 plan includes 100 international minutes to 35 countries with the $30 plan including 200 minutes, although extras such as roaming aren’t included. In terms of coverage, all plans are powered by Optus 3G and 4G nationwide networks.

The winner of our 2019 Canstar Blue Telco Award for SIM-Only Provider of the Year, Vodafone continues to offer value-packed postpaid plans to customers who are happy to bring their own phone. Offering solely month-to-month options with no lock-in contracts, Vodafone’s plans are available from $40 per month, and include unlimited standard national talk and text, plus great high-speed data inclusions.
All of Vodafone’s postpaid plans now feature unlimited data capped at 1.5Mbps, in addition to your included high-speed data – a great way to prevent overage fees and bill shock. Selected plans also include international calling minutes, and customers on month-to-month plans can add data-free streaming and entertainment passes from an additional $5 per month.

Another Optus network reseller, Vaya offers a modest range of lower-priced, bring-your-own-device postpaid plans, with both monthly and six-month terms available. Prices begin at $16 for 2GB of data on a month-to-month plan, with data options available up to 50GB (or 60GB on a six-month term).
All plans include unlimited standard national calls and SMS, and international calls are available from 2c per minute. The lack of bonus features and perks, such as included international calls, may be off-putting if you’re after a bells-and-whistles plan, but the great value data and unlimited talk and text keeps things simple. Month-to-month plans also auto-renew, but you’re free to cancel at any time without penalty.

Known mostly for its competitive range of broadband and NBN plans, iiNet also offers a small selection of bring-your-own-phone plans. Prices begin at $15 per month for 1GB of data, up to $37.99 for 9GB.
Unlike most other providers in our 2019 ratings, iiNet doesn’t include unlimited national talk and text with all plans; its $15 and $19.99 options feature $550 of monthly call and text credit. This is something to be aware of if you’re considering iiNet, but the telco’s two highest-tier plans do feature some included international calling credit. All plans offer coverage on Optus’ 3G and 4G networks.

Ranking in eighth place in our 2019 review, Telstra recently re-designed its postpaid plans, upping its data offerings significantly across all four plans. Prices start at $55 per month for 40GB of data, up to $115 per month for a hefty 180GB.
Although Telstra isn’t the most affordable provider, its plans are undoubtedly feature-packed. Along with unlimited standard national talk and texts, all plans feature unlimited speed-capped (1.5Mbps) data in addition to your full-speed gigabytes, as well as data-free sports streaming and data-free Apple Music. Three months of BINGE access is also included on all three plans. You’ll also get free Telstra Air Wi-Fi when you connect to any hotspot around the country.
The Medium, Large and Extra Large plans also include free access to Telstra’s 5G network, whereas customers on the Small plan will have to pay an additional $15 to access the network.

Customers on plans of $39 or more also enjoy unlimited standard international talk and text to 35 countries, plus 2GB of overseas mobile roaming data with the $59 plan and 4GB of roaming data with the $79 option.

There are plenty of great SIM-only postpaid deals on offer if you’re ready to bring your own phone to the party. But it’s important to understand exactly how these plans work: unlike prepaid phone plans, going postpaid means you could be charged more than you were expecting to pay.
Postpaid phone plans require you to pay your bills at the end of each billing period. This means that if you exceed your plan’s data limitations along the way, you’ll be charged extra for doing so. Excess data is usually charged at $10 per gigabyte, but some providers charge more; others charge by the megabyte instead, which means costs can quickly add up if you’re not careful.
The main advantage of postpaid plans is that you’ll never be left unable to make a call, send a text message, or use mobile data to chat online. If your prepaid plan expires, you’ll need to spend extra money there and then to get your service back up and running. However, postpaid plans allow you to keep using your service, and simply settle the bill later.
The main disadvantage of postpaid phone plans is the potential to blow out your budget if you’re not careful. Make sure that you know exactly what you will need to pay for going over your plan’s inclusions, keep an eye on your data use, and make sure that exceeding your monthly allowance doesn’t become a habit. If it does, you would be better off upgrading your plan, rather than paying extra in excess charges.
The safety net of being able to make calls whenever you need to means that postpaid phone plans are probably a good idea for those who use their phone a lot. They may also be the preferred choice for parents looking for a phone plan for their child.
If keeping close tabs on your spending is important to you, then prepaid may be the wise alternative. But when it comes to ease of use and maximum bang for your buck, it’s hard to look past postpaid plans.

Canstar Blue surveyed 9,000 Australian adults across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by Qualtrics. The outcomes reported are the results from customers within the survey group who currently have an active SIM-only mobile phone account in their name and pay the bills – in this case, 2,424 people.
Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then by mean overall satisfaction. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criteria.
