EastESIM is designed primarily for data connectivity, providing you with seamless internet access across Asia. As a data-only eSIM, it does not support traditional voice calls or SMS. Therefore, for critical situations requiring emergency services like dialing 110 (police) or 119 (fire/ambulance) in Japan, you should use your primary physical SIM card, a local landline, or a VoIP service like WhatsApp Call if you have a data connection.
