Setting up a Dual SIM from an eSIM notification
Look for a notification or Settings option about installing a cellular plan, and tap it.
This notification may appear after you've set up a new plan with your carrier or after you've provided your carrier the necessary details to initiate eSIM setup on their end. Your device needs to be connected to the Internet via Wi-Fi for the notification to appear.
Tap Continue.
Tap Continue again.
You can give each of your cellular plans a label, such as “personal” or “business.” This makes it easier to pick the right plan for calls and messages or when selecting a default plan and number to use with specific contacts.
Select a default plan for calls and messages. Tap Continue to select one for iMessage and FaceTime.
The labels will match whatever you set in the previous step.
Select the default plan and number to use for cellular data. Tap Continue to complete eSIM setup.
When you’re on a call on one line, your device can use your other line for data if you enable Allow Cellular Data Switching.
You've completed the steps!
