With eSIM, switching between mobile plans takes just a few taps—no need to swap physical SIM cards.
On iPhone
Open the Settings app and go to Mobile Service (or Cellular). You’ll see all your stored plans listed there. To switch back to your primary line, select it for both Mobile Data and Default Voice Line. If you don’t need the travel eSIM anymore, you can either turn its line off or remove the plan completely under the SIMs section.
On Android
Go to the Settings app, then open Network & Internet (or Connections, depending on your device). Here you can manage both SIM and eSIM profiles. Select your primary SIM/eSIM for calls, texts, and data. Just like on iPhone, you can disable or remove the travel eSIM if you no longer need it.
