JR East announced the end of the Mobile Suica ¥1030 annual membership fee for all Android devices on February 26 2020. Mobile Suica is free for Apple Pay users. JR East also announced the end of Symbian OS feature phone support with most devices being cut off from Mobile Suica on February 25 2020, and the rest following on December 22 2020 along with some Android devices.
All of the ‘offed’ devices can still use Suica for transit and purchases but are limited to cash recharge which can be done at station kiosks and any convenience store. Users who want to keep their Mobile Suica account will have to migrate to an eligible Apple or Android device.
JR East is also terminating Mobile Suica Shinkansen e-ticket purchases this year and will replace it with a new service similar to JR Central’s Smart EX. Details should be coming soon.
All in all it looks like JR East is clearing the Mobile Suica deck for the 2021 Super Suica launch.
