Cheap smartphone SIM user satisfaction

Overall, how satisfied are you with your cheap SIM? graph of japanese statisticsMMD Labo recently published the results of their survey into user satisfaction with cheap smartphone SIMs.

Demographics

Between the 21th of April and the 7th of May 2015 1,250 users of cheap smartphone SIMs completed a private internet-based questionnaire. The only other demographics offered were that there were 250 users of each of the five leading brands, OCN Mobile One, IIJ mio, BIGLOBE LTE 3G, Rakuten Mobile and b-mobile.

I currently have a standard, expensive SIM (around 5,000 yen even with various family discounts), but in Autumn my two-year contract is up, so I am very tempted to go for one of these cheap cards, especially as I make almost no phone calls; under 2,000 yen per month seems very possible. I’ll keep my existing phone, a Sharp SH-04F, as it’s still in good shape and I don’t see any new features in the last two years that make me want to upgrade.
