Check the battery. Is it charged, properly fitted, and are 
the contacts clean and dry?

Do you have a clear view of the sky?

Did you enter the number in international format? All 
calls made from the Iridium satellite system must be

Check the signal strength meter. If the signal is 
weak, move to an open space or, if you are in a

Registration or if in GSM cellular mode try Manual 
Selection, or try another network.

audible ringer.
