Please note: this troubleshooting is for GPS tracking via the SMS functionality of the Iridium GO! it is not for tracking via a DataHub /Iridium GO! installation.

Have you activated a new Iridium GO! SIM card which has generated a new Iridium phone number? We will need this number to update your settings at our end.

Do you have a Standard or Professional forecast subscription with us, which is a requirement for tracking to work.

Please check the unit is getting a GPS position on the LCD display of the Iridium GO!. If there is no GPS Lat/Long displayed, the unit does not have a GPS fix.

Can you please power the unit off for 5 mins and then back on again, and please place the unit on deck to ensure it has good GPS reception. The external antenna is only for the Iridium signal, not for GPS reception. In most cases this fixes the issue.

If the power off does not work, please check that you have the GPS tracking turned on in the Iridium GO! App.
