【*#06#】How to check if your device supports eSIM/dual SIM

We'll talk about "*#06#" that allows you to easily check if your device supports eSIM or dual SIM

It may seem a little suspicious, like some kind of password, but it's not like that at all; it's a very useful number, so I hope everyone will make use of it

There are also several other related articles about eSIMs, so please take a look at them along with this article

[Observation] There are many smartphones in Japan that do not support dual SIM or eSIM

What is this number anyway?

First of all, regarding this number, "*#06#" is used to display the "IMEI (International Mobile Equipment Identity) number."

you can also by opening the phone app on your smartphone and entering *#06#

By the way, IMEI is a globally recognized management number for devices, and is assigned a "unique individual number (15-16 digits)"

This unique number allows you to determine the device's manufacturer, country of origin, serial number, etc. For example, when unlocking the SIM lock, you provide your device's IMEI number to your carrier

The carrier will then use the IMEI number to identify the user's device and proceed with the official SIM unlock procedure

How to check if your phone supports eSIM/dual SIM

Now we get to the main topic, and I will explain it using actual screenshots

Open the Phone app on your device and enter *#06#

iPhone sample screen

Android sample screen

Explanation of each information

① EID

This is called the Embedded Identity Document and it displays information about the eSIM

② IMEI

The information about the IMEI that was opened earlier is output

The information in this section is for the first SIM card slot

When unlocking the SIM lock, etc., you only need to provide this first piece of information

③ IMEI 2

Similarly, information about the IMEI is output

The information in this section is for the second SIM card slot

What can you determine from this information?

Regardless of whether you are using an iPhone or Android, you will probably see a screen similar to the one above, but by sorting through the contents, you can determine the device information as shown below

① "The EID, which is the eSIM identifier, is displayed" → It is highly likely that eSIM can be used on your device

③ "Second IMEI information is displayed" → Two SIM slots are recognized, so there is a high possibility that dual SIM can be used.

summary

What did you think?

There were a lot of foreign words and alphabets, so it may have been a little confusing, but I've summarized the content below

1. Open the phone app on your device and enter *#06#
2. If the EID is displayed on the screen
3. If IMEI 2 is displayed on the screen

As I mentioned briefly at the beginning, of course, you can manually check this information from the settings screen on any smartphone operating system

However, I personally find the easiest and most straightforward method to display this number, and it can be checked in the same way regardless of the smartphone's operating system

This is extremely convenient, and especially on Android, where the settings screen itself is different for each model, it's a simpler way to check

However, it is important to note that the information you can obtain using the above steps is for reference only

be sure to check with the smartphone seller (manufacturer or carrier) before purchasing an eSIM or using the dual SIM function
