Here are some suggestions for what might be stopping you from installing Once Mobile:

  • Is your tablet connected to the internet?  Check that Wi-Fi or mobile data is turned on, and that aeroplane mode isn't enabled.
  • Is your tablet a compatible device? Once Mobile will run on any Apple iPad running iOS 8 or later and on Android tablets running Android 4 or later. This should cover all devices produced since 2013
  • Do you have enough storage space on your tablet?  You can check how much space you have in the settings area of your tablet.

If you have tried all of the above, and still can't install Once Mobile, contact us at or raise a support ticket giving us a description of the problem including any error messages.
