  • Purge text messages regularly.
  • Delete cached data from mobile browsers.
  • Do not allow mobile browsers to store mobile banking credentials.
  • Do not disclose personal information via text messaging.
  • Do not leave the device unattended.
  • Visit trusted sites only and don't click on suspicious e-mail messages and embedded links, just as on a computer.
  • Contact Trona Valley immediately if the device is lost or stolen.
  • Do not "jailbreak," "root," or otherwise modify the phone.
