The service was launched on November 1, 1998 and went into Chapter 11 bankruptcy on August 13, 1999. Its financial failure was largely due to insufficient demand for the service, the bulkiness and cost of the handheld devices compared to cellular mobile phones, and the rise of cellular GSM roaming agreements during Iridium's decade-long construction period.
Mismanagement has also been cited as a major factor in the program's failure. In 1999 CNN writer David Rohde detailed how the he applied for Iridium service and was sent information kits, but was never contacted by a sales representive. He encountered programming problems on Iridium's website and a "run-around" from the company's representatives. After Iridium filed bankruptcy it cited its "difficulty [in] gaining subscribers".
The Iridium satellites were, however, retained in orbit, and their services have been re-established in 2001 by the newly founded Iridium Satellite LLC, partly owned by Boeing and other investors. The system is being mainly used by the US Department of Defense for its communication purposes. However, it is open for everyone with global communication needs; typical customers include oil companies, scientists, and globetrotters.
The initial commercial failure of Iridium has had a dampening effect on other proposed commercial satellite constellation projects, including TeledesicTeledesic was a 1990s proposal to build a commercial broadband satellite constellation for Internet services. The proposal was extremely ambitious, and was gradually scaled back in complexity and number of satellites as market expectations for the sale of.

Phone rates from land lines to Iridium phones are $2 to $4 per minute, from Iridium to land lines about $1.50 per minute and between Iridium phones less than $1 per minute. Iridium and other satellite phones may be identifiable to the listener because of the particular "clipping" effect of the data compression and the time lag due to the long travelling path of the signal. Iridium operates at a data rate of 2400 baud, which requires very aggressive voice compression and decompression algorithms.
Iridium phones are mainly available from two vendors, KyoceraKyocera (, also known as Kyoto Ceramics is a Japanese company based in Kyoto, Japan. They were founded in 1959 by Kazuo Inamori. They produce ceramics and printing related devices, as well as a comprehensive line of imaging products, 35mm and medium forma and MotorolaMotorola started as Galvin Manufacturing Corporation in 1928. The name of the company was changed to Motorola in 1947, but the word had been used as a trademark since the 1930s. The company is based in Schaumburg, Illinois, a Chicago suburb. Founder Paul. Kyocera phone models SS-66K and SD-66K are no longer in production, but still available in the second hand and surplus market. The Motorola phone 9500 is a design from the first commercial phase of Iridium, whereas the current 9505 model is a more modern design which is especially popular in military applications.
Iridium phone numbers all start with +8816 or +8817 (which is like the country code for a virtual country) and the 8-digit phone number.
Because of the satellites' peculiar shape with three polished door-sized antennas, 120 degrees apart and at 45 degree angles with the main bus, the Iridium satellites have a highly visible satellite flareSatellite flare is the phenonmenon caused by the huge reflecting surfaces many satellites have today. In their orbits, the antennas of satellites directly reflect sunlight, creating a predictable and quickly moving illuminated spot of about 10 km diameter. On their orbits, the antennas directly reflect sunlight, creating a predictable and quickly moving illuminated spot of about 10 km diameter when the reflected beam hits the earth. To a spectator this looks like an extremely bright flare in the sky with a duration of only a couple of seconds. Some of the flares are so bright (up to -8 magnitude) that they can be seen at daytime, but they are most impressive after dusk and before dawn. This flashing has been of extreme annoyance to astronomers in that the brightness of the satellites disturbs observations and can damage sensitive equipment.
