Web App / Desktop ← Knowledge Base How do I use mysms on my computer? My SMS/MMS from desktop could not be sent. What can I do? What does the notification “Messages 24h not synced” exactly mean? How do I disable notifications? Can I send MMS? Why are MMS sent from the web/desktop/tablet not shown in my default SMS app on my phone? Why are long messages split into separate SMS in the web app?
