For a Second Consecutive Year, au Ranks Highest in Customer Satisfaction with Mobile Phone Service in Japan

TOKYO: 30 October 2013 The gap in satisfaction scores between the highest- and lowest-performing mobile phone providers in Japan narrows considerably in 2013, according to the J.D. Power Asia Pacific 2013 Japan Mobile Phone Service Satisfaction StudySM released today.

The study, now in its 15th year, examines customer satisfaction with their mobile phone service provider across six factors (listed in order of importance): services offered1 (31%); network quality (21%); cost (20%); handset (14%); after-sales service (8%); and dealer/ retailer experience (5%). Overall satisfaction is based on a 1,000-point scale.

Key Findings

  • Among providers ranked in the study, au ranks highest in overall satisfaction for a second consecutive year.

  • Although the satisfaction gap between the highest- and lowest-ranked providers remains wider in network quality than in the other factors, the gap has decreased sharply from 2012.

  • Users of VoIP application voice communication services experience problems at rates approximately three to six times higher than those who use provider services.

  • The gap in overall satisfaction between the highest- and lowest-ranked providers has narrowed to seven index points in 2013 from 33 points in 2012. At the factor level, the gap between the highest- and lowest-performing providers remains widest in network quality again this year (58-point gap in 2013 vs. 119-point gap in 2012).

VoIP users experience high rate of problems

The proportion of smartphone users in Japan has increased to 43 percent from 30 percent in 2012. The usage rates for mailmessages, charts, stamps, etc.and voice communication services among customers using LINE, Skype and other VoIP applications are 67 percent and 51 percent, respectively.

The study finds that users of VoIP application voice communication services experience such problems as voice break-up or interruption at rates three to six times higher than those who use provider services. Although many VoIP voice communication services are free, only 25 percent of users indicate having a strong intention to use VoIP application voice communication services, while 64 percent of users indicate having a strong intention to use mobile phone provider voice communication services.

With a score of 558 points, au ranks highest in overall satisfaction for a second consecutive year and performs particularly well in the services offered and cost factors, on par with 2012. NTT DOCOMO (556 points) ranks second and performs particularly well in network quality and after-sales service, the same as in 2012. Third-ranked SoftBank (551 points) performs particularly well in handset, as in 2012, and in dealer/ retailer experience.
