Below is a simple guide on how to use both eSIM and physical SIM when traveling to Japan.
Here is a detailed step-by-step guide to setting up a physical SIM card in Japan in a simple and easy-to-understand manner.
Step 1: Check if your phone supports Japan SIM cards
Before inserting the SIM card, check if your phone is unlocked, meaning it can use SIM cards from different carriers. If your phone has been used with multiple carriers before, it is likely already unlocked.
Step 2: Insert the SIM card into your iPhone or Android device
Power off your phone.
Use a SIM ejector tool to remove the SIM tray.
Place the Japan SIM card correctly in the tray.
Reinsert the tray and power on your phone.
If your phone has dual SIM slots, insert the Japan SIM card into the primary slot for better performance.
Step 3: Set up APN to connect to the network
Most Japan SIM cards do not automatically connect to the network, so you need to manually configure the APN (Access Point Name) by following these steps:
For iPhone
Go to Settings > Cellular > Cellular Data Options > Cellular Data Network.
Enter the APN details provided by your SIM provider (usually found in the instruction manual included with your SIM).
Save the settings and toggle Airplane Mode on and off to update the network settings.
For Android
Go to Settings > Network & Internet > Mobile Network > Access Point Names (APN).
Tap Add APN.
Enter the APN details as per your SIM provider’s instructions, then save the settings.
Restart your phone to apply the changes.
Each mobile carrier has different APN settings, so make sure to check the instruction manual included with your SIM card.
Step 4: Activate the SIM card
If your phone displays signal bars and a 4G/5G icon, your SIM card has been successfully activated. If you don’t see any signal, double-check the APN settings or restart your phone.
Step 1: Receive your eSIM QR code
If you buy eSIM Japan online from Way2go or another provider, you will receive an email containing your eSIM QR code.
Step 2: Install the eSIM on your phone
Go to Settings → Cellular → Add eSIM or Add Cellular Plan.
Select Scan QR Code and scan the QR code received via email.
Wait for the eSIM configuration process to complete.
Step 3: Configure APN (if necessary)
Some eSIMs automatically detect the APN settings. However, if the connection does not work, you may need to manually enter the APN settings (follow the same steps as for a physical SIM).
Step 4: Check your connection
Turn on Wi-Fi → Turn off Wi-Fi → Check if the eSIM has mobile data access.
If the connection is not working, try enabling and disabling Airplane Mode or restart your device.
In conclusion, buy SIM in Japan before your trip helps you save costs, ensures a stable connection, and prevents service interruptions.
