Solution 1: Check the signal and dialing format

Follow these steps to confirm the device is registered on the Iridium network and that the number is dialed correctly.

1. Extend the antenna to power on the Iridium GO!.

2. Wait until the screen shows “Searching,” followed by “Iridium,” which confirms registration.

   • Example: +1 416 253 6008

7. Select the green phone icon to place the call.
