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).
