[eSIM] Setup Method ~ iOS ~

Have you heard of "eSIM (Embedded SIM)"?
Most people probably use their smartphones with a physical SIM card inserted, but in Japan, eSIM is still relatively unfamiliar, and the honest impression is that it's still "not very clear."
I myself have only recently started using eSIMs, and before I experienced their convenience, I had a vague idea that they were "difficult."
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
If 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 ~
*Please note that this article is based on iOS 17.5.1 for iPhone 15
Overview of the work flow
After purchasing an eSIM, there are two main setup steps to follow:
- Installing an eSIM
- Roaming Settings
As a prerequisite, we recommend that you first confirm that the eSIM you purchased is compatible with your iPhone, and then perform steps (1) to (2) above, one to two days before you actually use the eSIM, and (2) above, to set up roaming after you arrive at your destination
Let's get started right away
① Install eSIM
First, tap ① "Settings" > "Mobile Data"
② Tap "Add eSIM"
③ Tap "Use QR code" and scan the eSIM QR code
Once the scan is complete, click "Continue" in ④ and your eSIM installation (activation) is complete!
What did you think?
It's easier than you might think, and I think it's very convenient that you can just scan a QR code
With physical SIM cards, there are many inconveniences, such as losing the SIM card itself when replacing it, or not having the pin to remove the card slot
However, with eSIM, as long as you're connected to the network, you can start setting it up by simply scanning the QR code with your device, so it's easy!
Now that you've added the eSIM, you can't use it yet. To start using it, you'll need to configure the roaming settings (explained in the next section) and prepare to use the network at your destination
② Roaming settings
Once again, tap ① "Settings" > "Mobile Data"
② Tap the eSIM you just added
Turn on "Turn on this line" in ③ and "Data roaming" in ④ to complete the setup
This completes all the settings for the eSIM
As explained at the beginning, these roaming settings are "settings for using the network provided by the local telecommunications carrier at your destination," so be sure to perform them after arriving at your overseas destination .
summary
One of the major advantages of eSIM is that it is less hassle than a physical SIM
The QR code will be sent to you via email, so there is no need to wait for delivery to your home. Once your overseas stay is over, you can simply delete the eSIM, so you can start using it anywhere with ease
Also, depending on the eSIM service and plan, if you run out of data while traveling abroad, you may be able to add more data for an additional fee
