Why does SMS for iChat think my device is offline?

Sometimes, SMS for iChat makes sure it can talk to your device. If your device doesn’t respond in time, this can cause lost / delayed messages and other unexpected issues.

If SMS for iChat thinks it can’t talk to your device, try these steps:

Android

 

  • Check for updates in the Play Store.
  • Try switching from WiFi to your data connection (or the other way). This will reveal if there is a network issue preventing us from talking to your phone.
  • Check to see if disabling any power saving / battery optimization modes on your Android phone helps.
  • Restart your phone (give it 30 seconds after booting up to get connected).
  • Did you restore the app with Titanium Backup? That can cause this error. Either do a clean install from the Play Store or tap Clear data for our app in Android’s system settings and sign back in.
  • Does sending work when your phone is unlocked and the screen is on but otherwise not? If so, this may be because your phone on an IPv6 WiFi network. Some devices ignore incoming data when the screen is off and connected with IPv6 (acknowledged by Samsung Developers here). See if you can disable IPv6 on your WiFi or Android device to fix this.
  • If your phone is on wi-fi, and you are on a corporate wi-fi network (e.g. at your job or school), sometimes important internet ports are blocked on these networks.  Ports 5228, 5229, and 5230 are needed by Google Play Services (which SMS for iChat uses to communicate with your phone to send messages).
