Tips from Iridium for keeping your satellite phone in good condition:

· Test your phone monthly.

· Keep the battery charged. For optimal performance, completely discharge before fully charging.

· Ensure SIM card is locked in place. Remove the battery to check if the tray is securely positioned and locked.

· Protect the phone’s antenna. Stow the antenna in the “down position” when not in use.

· Call outside with a clear view. Avoid obstructions to the sky and the horizon such as buildings and trees.
