I am unable to obtain signal on my handset. What can I do to troubleshoot?

Confirm the following

1. The SIM card may not be locked in the SIM tray. Inspect the SIM tray and upon locking a little “click” will be heard.

2. The antenna is extended and angled at 45°. The angling is required because when holding the phone up to your ears at a 45°, the antenna is angled as well, this will ensure it is pointing straight up.

3. Iridium Service is provisioned by your service provider for the SIM installed in the phone.
