FeliCa Dude points out that Pixel 4a (5G) and Pixel 5 devices use the latest Mobile FeliCa 4.1 but are not yet qualified for Mobile PASMO even though they run Suica just fine. PASMO support lists them as in the works.
Worse than that however is that OEMs are still releasing Osaifu Keitai devices with older Mobile FeliCa 3.x/4.0 factory fixed firmware that either forces the user to choose between installing Mobile PASMO or Mobile Suica, or doesn’t work with Mobile PASMO at all. It’s a real snapshot of the Android hardware dilemma.
Apple Pay PASMO is supported in iPhone 8/Apple Watch Series 3 and later. iPhone 7 JP model users are not happy about that but the writing was on the wall with the Apple Pay Octopus ‘iPhone 8 and later’ configuration. Going forward, iPhone 8 and two-factor authentication Apple ID will be the base configuration for using Mobile ICOCA, Super Suica and other mobile transit IC cards.
