Why am I not receiving email or SMS messages in my Iridium Cell Phone ZOLEO App?

  If you're not receiving ZOLEO email or SMS messages in your ZOLEO App, it could be due to several reasons. First, ensure your ZOLEO communicator and app are properly linked. If the Weather and SOS tabs aren't visible, try connecting them. Check your internet coverage; without it, position your ZOLEO communicator for good satellite coverage and connect it to the app. Also, power saving settings might delay message delivery, especially if set to 60 minutes. Try manually checking for messages or adjusting the power saving setting for more frequent checks.

  If messages appear with a red failure icon after trying to send from your Iridium Cell Phone, make sure you have either internet or satellite coverage. Also, ensure that your ZOLEO communicator is properly connected to your ZOLEO App. If both are true, press and hold the failed message and select 'Retry'.

  If your Iridium Cell Phone ZOLEO communicator is on but not responding, first try powering it off and then back on again. If that doesn't work, close the ZOLEO App using the Task Manager on your smartphone and then reopen the app. As a last resort, conduct a hardware reset.

  If a Check-In message failed to send from your Iridium Cell Phone, ensure that your ZOLEO communicator and ZOLEO App are within range and clear of obstructions. If they are, step outside with your ZOLEO communicator and ensure it has a clear line of sight to the sky. Then, try sending another Check-In message.
