Maximum Reliability

  • Multiple service providers for sending SMS/email in the most timely and reliable manner
  • WISO is designed to work in an uncertain environment, it copes with unreliable network condition and sends the most up-to-date information to the server when possible. The server is equally designed to cope with a client with bad network access.
  • When the server detects that no emergency contacts has opened the included location tracking web link, it automatically resends SMS/email with the link to the contacts several times to improve the chance of the message being seen.
