JUNE 19, 2017

Beam has announced that some Iridium 9555/9575 (Extreme) handsets when upgraded to the latest firmware version (HT17001/HL17001) and docked in compatible Beam docking stations may display the error message “USB Cable DISCONNECTED/USB Cable CONNECTED” preventing normal operation. Other issues such as the handset rebooting or switching off while docked may also occur.

If you have already upgraded your firmware, are using Beam Docking Stations and have received the error code above, please revert your firmware to the previous version.

If you have not upgraded your firmware and are using a Beam Docking Station, upgrading to the latest firmware is NOT recommended until a fix for the error is received from the manufacturer.

If you have any questions, contact us for more information!

How does someone place calls to my satellite phone?

There are a few ways to contact the Iridium handset:

  • The caller will dial their international access code (i.e., from the US 011) + your 12-digit satellite phone number. The caller pays for the call based on the rates that their long-distance service provider sets to dial the 881 country code. There is no cost to you for these incoming calls. If the call does not go through, it means that the caller's long-distance service provider does not have the 881 country code loaded into their system. Proceed to option #2 or #3.
  • The caller may dial the 'local' U.S. access phone number (1-480-768-2500). They will then be prompted to input your 12-digit satellite phone number, and the call will be placed to your Iridium phone. The cost to the caller is a standard long-distance call to Arizona. The cost to you for this service is $1.60/minute incoming. Please keep in mind that it may be cheaper to dial this U.S. access number from other countries, if the country that the caller is in does not have the '881' country code loaded.
  • If the service plan you subscribed to has voice mail and short messaging service (SMS), the person trying to contact you can send a short text message (under 160 characters) directly to your handset. Keep in mind that your handset must be on to receive the message, as the Iridium system does not store these messages. There are two ways to send a SMS message:
    • Visit our Send a Text Message page.
    • Open a new e-mail, and send to Do not include a subject line, as it will not be included in the message body. Type in a short text message (under 120 characters), and hit 'Send'.
