[eSIM] Setup Method ~ iOS ~

Do you know about "eSIM (Embedded SIM)"?

I think most people probably use their smartphones by inserting a physical SIM card. However, in Japan, there is little familiarity with eSIM, and I think the honest impression is that people still don't really understand it.

I have only recently started using eSIM, and until I realized how convenient it is, I had vague impressions of it being difficult or confusing.

we will explain how to set up an eSIM after purchasing it , in order to dispel those negative impressions and let you know how convenient it is

In the unlikely event that you are unable to connect to the network after completing the setup described in this article,

Please refer to the article below to check your APN settings!

[eSIM] APN Settings Explained ~ iOS Edition ~

*This article was created based on iOS 17.5.1 for iPhone 15. Thank you for your understanding in advance.

General flow of work

There are two main setup steps to be performed after purchasing an eSIM:

1. Installing an eSIM
2. roaming settings

As a prerequisite, please make sure that the eSIM you purchased is compatible with your iPhone.

you install the eSIM in ① 1-2 days before actually using the eSIM, and perform the roaming settings in ② after arriving at your destination.

So let's go right away!

① Installing eSIM

First, tap ① "Settings" > "Mobile communications".

② Tap "Add eSIM".

③ Tap "Use QR code" and scan the eSIM's QR code.

Once the scan is complete, click ④ "Continue" to complete the eSIM installation (activation)!

What do you think?

I think it's easier than you might think, and it's very convenient to just scan a QR code.

In the case of a physical SIM, I think there are many inconveniences, such as losing the SIM itself when replacing it not having a pin to take out the card slot at hand

However, in the case of eSIM, as long as the network is connected, you can start setting up by simply scanning a QR code with your device, so it's easy!

Now, the eSIM has been added, but it cannot be used as it is. To start using it, you will need to perform the "roaming settings" explained in the next section and prepare to use the destination network.

② Roaming settings

Once again, tap ① "Settings" > "Mobile communications".

② Tap the eSIM you added earlier.

Turn on ③ "Turn on this line" and ④ "Data roaming" and the settings are complete!

All eSIM settings are now complete.

As explained at the beginning, these roaming settings are "settings for using the network provided by the local telecommunications carrier at your destination," so sure to perform them after arriving overseas .

summary

In the past, I ignored eSIM because I thought I didn't understand it, but when I summarized it myself, it was very easy and easy to understand.The biggest advantage is that it requires less effort than physical SIM. I thought it was one of the.

With an eSIM, you will receive a QR code via email, so it won't take long to have it delivered to your home, and you can simply delete the eSIM when your overseas trip is over, so you can easily start using it anywhere. .

Also, depending on the eSIM service and plan, if you run out of data while traveling abroad, you may be able to top up your data for an additional fee.
