How to set up and switch to eSIM
Using an eSIM on an iPhone has many benefits, including eliminating the need for a physical SIM card and making it easier to manage multiple lines.
This article is for iPhone users and will introduce everything from compatible eSIM models to initial setup and how to switch between multiple eSIMs.
What devices are supported? What are the requirements?
eSIM-compatible iPhone models
eSIM is available on all iPhone models released after the iPhone XS/XS Max/XR released in 2018.
If you want to know the model name of the iPhone you are using, you can check it by going to "Settings" > "General" > "About" and checking "Model Name."
Latest iOS version recommended
Just as there are compatible models, there are also compatible operating systems. Basically, it is said that eSIM can be used on iPhones with iOS 13 or later. We recommend installing the latest version of iOS just to be safe.
Stable Wi-Fi environment
Since communication is required during activation, a stable Wi-Fi environment is required.
Make sure to connect when you can ensure a stable connection.
QR code or activation code
For Otegaru eSIM, after purchasing the product, a QR code and PDF instruction manual will be sent to you by email. Please keep them safe as they will be used for activation.
QR codes and activation codes are often sent for other products as well, so be sure to keep them in a safe place and do not delete them.
How to set up your eSIM
Setup using QR code
"Settings" > "Cellular" > "Add Cellular Plan" > "Use QR Code"
Tap in order to scan the eSIM QR code. Follow the on-screen instructions to complete the setup.
Manual setting (if QR code cannot be read)
Settings > Cellular > Add Cellular Plan > Enter details manually
Tap in order and enter the activation code directly. Then follow the on-screen instructions to complete the setup.
How to manage your eSIM profile
Checking current eSIM status
You can check which SIM is connected by going to "Settings" > "Mobile Data".
Manage multiple eSIM profiles
On iPhone 13 and later, you can activate two SIMs at the same time, either a physical SIM and an eSIM, or a combination of two eSIMs. Also, on iPhone 14 and later, you can save up to eight profiles.
Older iPhones (such as the iPhone XS, XR, and XS Max) can store up to 20 eSIM profiles, but only one can be active at a time.
Please note that this varies depending on the model.
How to view multiple eSIM profiles
To check if your eSIM profile has been downloaded, follow these steps:
"Settings" > "Mobile Communications" > "Mobile Communications Plans"
Tap to see the plans displayed.
How to rename your eSIM profile
"Settings" > "Mobile Communications" > "SIM"
Tap and select the eSIM you want to edit.
Tap "Cellular" or "Cellular plan name" to select the default eSIM name, then change the name in the Custom name field to complete the name change.
It may be a good idea to remember that you can rename profiles, as this will make them easier to identify when you have multiple profiles saved.
How to switch between eSIMs
Data communication switching
"Settings" > "Mobile Communications" > "Mobile Data Communications"
Tap in order, then select the eSIM you want to use. Then check "Mobile data switching".
Switching between calls and SMS
"Settings" > "Mobile Data" > "Calls and SMS"
Tap in order to select the eSIM you want to use.
How to use the dual SIM feature
Using a physical SIM and an eSIM together
You can use a physical SIM and an eSIM at the same time. You can use the physical SIM for calls and SMS, and the eSIM for data communication, depending on the purpose. This has the advantage that you can use different phone numbers and data plans, or use a local SIM as an eSIM when traveling abroad.
Automatic switching between multiple eSIMs
Select the line you want to use under the "Mobile Data" section and turn on "Allow Mobile Data Switching" to enable automatic eSIM switching.
With this setting, when you make a voice call, the eSIM will automatically switch to the eSIM for data communication, allowing you to use the same eSIM for both voice calls and data communication.
troubleshooting
If your eSIM isn't recognized
Check for iOS updates
Make sure your iOS version is up to date.
How to reset your network settings
Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings
Tap in this order. Your iPhone should restart when you reset the network settings, so please confirm. When your iPhone restarts, the network settings will be reset and restored to their original state.
Please reconfigure your network settings from there.
How to update your carrier settings
"Settings" > "General" > "Information"
When you tap, a pop-up will appear, so follow the instructions on the screen to install the carrier update.
If the pop-up does not appear, there is no need to update.
By doing this, you can update the settings related to the mobile data network provided by your mobile phone company.
When the communication speed is slow
How to check and switch network modes (4G/5G)
You can check the network mode on the top right of the iPhone screen.
It is also possible to switch manually, so try this if your connection is unstable.
"Settings" > "Mobile Communications" > "SIM"
Tap in order and select the plan for your line.
Then tap "Voice and Data" and try out each of the options presented to you and select the network mode that gives you the best signal.
Optimization of "Mobile Data Communication Options"
Optimizing your mobile data usage can help you save data, maintain speed, and extend battery life. Here are some ways to reduce your mobile data usage.
"Settings" > "Mobile Data" > "Mobile Data Options" > "Data Mode" > "Low Data Mode"
Tap in order. Low Data Mode allows you to pause automatic updates and background tasks when your iPhone isn't connected to Wi-Fi.
The impact of VPNs and what to do about them
VPN stands for Virtual Private Network, a mechanism to protect against risks such as information leakage, tampering, and intrusion that may occur during data communication.
Conversely, this VPN can also cause your device to be unable to connect. If this happens, here's what you can do:
- Make sure the date, time, and time zone are set correctly.
- Make sure you have the latest software updates installed
- Restart your device
- Connect to a different network to see if the problem is with the network you were using
Erasing eSIM
How to erase your eSIM profile
"Settings" > "Mobile Data" > "Delete eSIM"
You can delete the profile by tapping
Points to note
If you want to cancel your mobile data plan, simply deleting the eSIM profile will not complete the cancellation. You will need to contact your carrier directly to cancel your plan.
Please note that if you delete the profile you are using, you will need to contact your carrier to obtain a new eSIM.
