A: If Expired certificate or Certificate not valid yet is displayed, even if the certificate

have skipped the setting of date and time when starting the device for the first time,
or the mobile network may have failed to update these settings to your device. To
resolve this, select Menu > Settings and Phone > Phone mgmt. > Factory
settings. Restore the factory settings, and when the device restarts, set the correct date
and time.
