Service Provider must use PCR to manage subscription management
  • GSM Number may change, deactivated or transfered to another subscriber
  • For these reasons Service Provider must use PCR number to make relation between Fast Login and its own Subscriber System.
  • PCR may change whereas phone number stays the same means there is a new subscription, in this case Service Provider must start with a new subscription flow.
