    Apple’s carrier information service has recovered, and Carrier Information lookups are now back online. However, SIMLock-only checks remain paused due to continued instability with Apple’s SIMLock service. Desktop Simlock checks for users on version 3.12.8f and above remain fully operational and are not impacted. We’re continuing to monitor Apple’s recovery progress and will reopen SIMLock-only API services as soon as stability is confirmed. Thank you for your patience. Please reach out to our support team if you have any urgent needs.
