Where does CHOICE get these numbers?
Overall satisfaction score
Our mobile satisfaction survey rates providers based on their own customers' feedback on how they're performing. Our 2017 survey covered a range of questions such as call clarity, internet speed, customer service and how clear the bill is to understand. The overall satisfaction score is an average of all these questions.
ALDImobile scored highest overall and high for reliability and value.
What matters to you
When choosing a mobile provider on a SIM-only plan, respondents told us that value for money (94%), network coverage (94%) and network reliability (94%) are equally important factors.
Interestingly, ALDImobile and Amaysim scored higher than Telstra and Optus for network coverage even though ALDImobile doesn't use all of the Telstra network and Amaysim uses the Optus network. This result may indicate that the overall stronger customer satisfaction of ALDImobile and Amaysim customers leads to a perception of better network coverage compared to Telstra and Optus customers when this is simply not the case.
Scoring the satisfaction rating
Satisfaction scores are calculated out of 100 by asking respondents to rate their service provider on various attributes and overall satisfaction on a seven-point scale ranging from terrible to excellent. The results are tested for statistical significance to verify scores that are statistically higher or lower than the average.
A provider needed 30 or more respondents to be included in our results. For the scores tables, the average score refers to the category average and includes not just the brands listed but also all other brands which had a sample of N<30 and didn't make it into our scores tables.
The CHOICE mobile satisfaction survey was conducted in May 2017. Australian residents aged 18 and over who have a mobile phone service (N=1994) completed the survey. CHOICE designed the survey and fieldwork, and Research Now executed the survey. Survey results have been weighted to be nationally representative of the Australian population as per ABS Census 2011.
The survey asked respondents about their mobile connection type (SIM-only or SIM and mobile), their current mobile provider, their satisfaction with their provider, and also about any problems they'd faced.
Why don't you cover my SIM provider?
Let's be clear: there are only three mobile network providers in Australia – Telstra, Optus and Vodafone. All the other companies you see advertising SIM plans are using one of these three networks (generally Telstra or Optus) with varying levels of coverage. Companies such as ALDImobile, Amaysim, Boost etc. are called Mobile Virtual Network Operators (MVNO). The fact that they can offer great deals is a good indication of how much profit is being made by Telstra, Optus and Vodafone.
We could only report on Amaysim, TPG and ALDImobile as these were the only companies with more than 30 responses in our satisfaction survey.
