For those planning a trip to Japan, ensuring your smartphone can connect to a network while in Japan is just as important as deciding where to stay.
A stable communication environment is essential for searching for information about tourist attractions, using map apps, and sharing travel memories on social media. However, in Japan, free Wi-Fi spots are surprisingly scarce, and the connections are often unstable.
That’s where an eSIM comes in handy. If your smartphone supports eSIM, it is a more convenient and cost-effective option compared to renting a Pocket Wi-Fi device or purchasing a local SIM card. With simple settings, you can instantly connect to the internet.
In this article, we will introduce an easy method to check if your smartphone is compatible with eSIM for use in Japan.
How to Check if Your Smartphone Supports eSIM
There are several ways to verify if your smartphone can use eSIMs sold in Japan. You can check through EID or by accessing the settings on both iPhone and Android devices.
Checking EID via Your Phone (Simple Method)
EID (eSIM ID) is a unique identifier for devices that support eSIM. By checking the EID, you can confirm if eSIM is available for use.
Using the Phone App
Open the phone app on your device.
Enter *#06# and dial.
The EID will be displayed.
This method works on both iPhone and Android smartphones.
By following these steps, you can easily determine if your smartphone supports eSIMs available in Japan.
EID
A screen with info will appear. If your phone is eSIM-compatible, you'll see an EID number in the list.It's not obvious on some phones, but the list is scrollable, so if you can't see EID, make sure you scroll all the way down. The EID number might also show as 'EID 2'.
Checking EID in Settings
For iPhone
Open the Settings App: Tap the "Settings" icon on your home screen.
Select General: Tap "General," then choose "About."
Check for Digital SIM: Look for an item labeled "Digital SIM" or "eSIM." If it’s displayed, your device supports eSIM.
For Android
Open the Settings App: Access the settings app on your smartphone.
Select Network & Internet: Tap "Network & Internet."
Check for Add SIM Options: Tap the "+" next to SIM and check if options like "Add eSIM" or "Add Plan" are displayed. If so, your device is eSIM-compatible.
What If the EID (eSIM ID) Does Not Appear?
If the EID does not appear, your device may not support eSIM. This is especially common in older models or certain Android devices. In such cases, refer to the device's user manual or the manufacturer's official website for confirmation.
Be aware that companies selling eSIMs may not provide accurate information about device compatibility if you do not have detailed model information. Therefore, it’s best to contact the company or manufacturer where you purchased your smartphone.
