If you experience any connectivity issues with your EastESIM in Japan, the first step is to try restarting your device. If the problem persists, connect to any available Wi-Fi – perhaps at your hotel in Tokyo, a convenience store in Osaka, or a café in Kyoto. Once online, immediately contact EastESIM's 24/7 customer support team via WhatsApp or email. Our dedicated team is well-versed in local networks, including partners like Docomo and SoftBank, and will guide you through troubleshooting to quickly restore your service.
