Mobage removed Pocket Frogs, Pocket Planes and Tiny Tower from the Google Play store and turned off the game servers on September 24th, 2015. Game play is no longer possible and all progress is permanently lost.
While we have re-ported Tiny Tower to Android, we have no current plans to port Pocket Frogs and Pocket Planes at the time. The iOS versions of these apps will still remain active but the data is not transferrable from the Android to iOS version. Future sequels or major updates could possibly support Android though.
For purchase related concerns from the previous Mobage version, please contact Mobage support at their website: http://support.mobage.com/ or via email at email@example.com.
