Postpaid Mobile Plans & Providers

Advertisement

Canstar Blue’s annual review of postpaid SIM-only providers compares plans from Amaysim, iiNet, Vodafone, Optus & Telstra based on factors including value for money, customer service, sign up & activation, billing, network coverage, plan flexibility and overall satisfaction.

See our Ratings Methodology.

Most Satisfied Customers | Amaysim

For the third year in a row, Amaysim has taken out top spot in our customer ratings for postpaid mobile plans. It earned top marks on value for money, sign up & activation, billing, network coverage and plan flexibility.

Amazing job! Amaysim still top for postpaid plans

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 now 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, bill information, network performance, plan flexibility, value for money and their 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 Amaysim and iiNet. While iiNet is a large provider in the internet space, it uses the Optus 4G network for its mobile services – as does Amaysim. In fact, Amaysim is the largest Mobile Virtual Network Operator (MVNO) in Australia, and has once again topped our customer satisfaction ratings.

The five telcos in our review of postpaid phone plans were rated in the following order for overall customer satisfaction:

  • 1st Amaysim
  • 2nd iiNet
  • 3rd Vodafone
  • 4th Optus
  • 5th Telstra

The result means Amaysim makes it three years in a row at the top.

  • Amaysim was again the only provider to score five stars overall, in addition to value for money, network coverage and most other areas. Note that Amaysim no longer offers new customers postpaid plans, instead electing to offer prepaid plans only.
  • iiNet and Vodafone both received four stars overall, with the former praised for its customer service.
  • Optus and Telstra were both awarded three stars overall. The only top marks went to Telstra with regards to network coverage.

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?

Amaysim Postpaid Plans

Amaysim has ceased offering postpaid plans, but did have five postpaid phone plans on offer, starting from just $10. Plans were SIM-only and offered on both a postpaid and prepaid basis, so the below prices and inclusions still apply but only as prepaid offerings. Plans max out at $50 per 28-days – this coming with 60GB data.

Amaysim benefits from having unlimited calls & texts with all plans, as well as international call allowances on the $30, $40 and $50 plans.  Note that the plans below are identical to its prepaid plans – if you wish to shop with Amaysim, you’ll be led to prepaid plans.

iiNet Postpaid Plans

iiNet is probably best known for its internet services, but it also has a fairly concise range of month-to-month, SIM only postpaid deals. iiNet kicks things off at $15, with plans maxing out at under $40. There is a $10 SIM card setup fee, but other than that what you see is what you get.

Vodafone Postpaid Plans

Vodafone is another provider that offers both 12 month and month-to-month SIM only options. Prices start at about $35 a month on 12 month terms and going up to $65 for 125GB of high-speed data (and unlimited data at a capped speed) and you’ll regularly get special offers such as bonus data and discounts. The month-to-month plans have less data for your money but you are able to add Vodafone passes to these plans for data-free music and video streaming, chatting or social media browsing. Many plans also come with generous international call allowances and access to $5 (per day) global roaming.

Optus Postpaid Plans

Optus has a few postpaid plans across both month-to-month and 12 month contracts. As it stands there are some incentives for signing on for a year, including cheaper plans, more data and other perks. On a month-to-month plan, you’ll get much less data than  on an equivalent 12-month option.

Postpaid Phone Plans Explained

As you can see above, there are lots of great postpaid SIM-only deals around. But before you go signing up with a plan, it’s important to understand exactly how these plans work because, unlike with prepaid phone plans, you could be charged more than you were expecting to pay.

With postpaid plans, you pay your bills at the end of each billing period. This means that if you exceed your plan’s limitations along the way, you will be charged extra for doing so. Excess data is usually charged at $10 per gigabyte, but some providers charge more and 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 been left stood by the side of the road unable to make a call, send a text message or use mobile data to chat online. If your prepaid plan had expired, you would need to spend extra money there and then to get your service back up and running. With postpaid plans, you can settle the bill later.

The main disadvantage of postpaid plans is the potential to blow out your budget if you are not careful. Make sure you know exactly what you will need to pay for going over your plan’s inclusions and make sure that doing so 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 plans are probably a good idea for those who use their phones 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.

Frequently asked questions

Canstar Blue surveyed 6,000 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 a prepaid mobile phone plan in their name and they pay the bills – in this case, 1,217 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 alphabetically. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criteria.
