Japanese government lists dual SIM iPhone models ‘non compliant’ for emergency call issues

The Japanese Ministry of Internal Affairs and Communications (MIC) has listed 15 dual SIM iPhone models including iPhone 13 as “non-compliant” to government technical standards due to an inability to place emergency calls in certain dual SIM use situations. Apple posted a Japanese only support page on October 23 that acknowledges the emergency call issue when both data only SIM and voice call SIM are installed with a workaround: users need to make sure the SIM number in Mobile Data settings is a voice SIM in order to make emergency calls to 110/118/119 numbers (police, coast guard, ambulance).

Apple needs to fix this issue as quickly as possible. They should have caught it before iOS 15 shipped.
