I've got a new Iridium 9555 Satellite Phone, now how do I use it?

Congratulations on your new Iridium 9555 satellite phone. If you're new to satellite telephones, you might be wondering, how do I use it? No problem, it’s easy and we’re here to help.

First thing’s first…on your Iridium 9555, remove the back to insert the SIM chip in the phone. Then reconnect the battery and let it charge for about 8-10 hours.

Now it’s time to make your call. To use the phone, go outside to get a signal. Be sure to avoid any large obstructions like buildings or dense trees that could block the connection from the phone antenna to the satellites in space. Make sure you extend the antenna and tilt it to the left or right so it is vertical when you hold the phone to your ear. Now press the top button to power on and wait for it to acquire a signal. As soon as it says “registered”, you are ready to place your call.

A great new feature of the 9555 is that it has a default prefix number entry mode so you don’t have to dial 00 before the country code as in previous models. Just enter country code, for the US that is 1, then the area code then phone number.

And that’s it, easy huh? Enjoy your phone and watch for future tips.
