SIM Not Working After Returning Home From Japan? (Fix Guide)
In this section, we will cover troubleshooting steps if your home-country SIM is not working after returning from Japan.
Many travelers report issues such as “SIM not working after returning from Japan trip” or being unable to reconnect to their local carrier. The following methods can help restore your connection.
7 Ways to Fix Home-Country SIM Not Working After Returning from Japan

Make sure your home country SIM’s network setting is set to “Automatic.” Here’s how to check it on both iPhone and Android with screenshots.
iPhone Network Settings

Toggle Airplane Mode On and Off
If your home country SIM isn’t switching properly, try turning Airplane Mode on and then off. This forces your phone to reconnect to nearby mobile network towers, which can often resolve connectivity issues.
Restart your device
Try restarting your smartphone. Temporary glitches or failed network handovers can often be fixed simply by powering off and on again.
Remove and reinsert the SIM card
If you’re using a physical SIM with your home country carrier, remove it from the SIM slot, clean it gently, and reinsert it. Poor contact between the SIM and the slot can cause connection issues, and reseating the SIM often resolves them.
Reset network settings
Sometimes, leftover Japanese network settings on your iPhone or Android—like Wi-Fi history, APN settings, or roaming preferences—can interfere with your home country SIM.
Performing a network settings reset often restores normal connectivity for your home carrier.
Note that resetting network settings will erase Wi-Fi passwords, VPN configurations, and Bluetooth pairings, but it won’t delete other personal data like photos or apps.
Items Reset When Performing Network Settings Reset
When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed.
Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
