News from Iridium reveals a new policy for Iridium SIM cards being used in Russia.
As of February 3, 2014, all new SIMs being used within Russia will need to be registered at http://www.iridium-russia.com in order to enable communications.
The registration information is very basic requiring only name and nationality plus equipment information — MSISDN, IMEI and ICCID.
Any SIM activated after February 3 and that has not been registered will not work within Russia. Any end-user attempting to utilize an unregistered SIM that is effected by this policy within Russia will receive a voice prompt when they try to place a call within Russia, which will direct them to the website or their provider in order to quickly register and restore service.
