[Phone] How to Set Up eSIM and Troubleshooting

What is eSIM?

 

An eSIM (Embedded SIM) is a digital SIM card that allows you to activate a mobile plan from a carrier without using a physical SIM card, enabling calls, texts, and mobile data.

*Note: eSIM support may vary by carrier, country/region, and device model. Please check for compatibility based on your specific situation.

 

How to Activate your eSIM?

Please contact your carrier to apply for an eSIM card.

The carrier may require your EID information during the application process. This information is related to whether your phone has a built-in eSIM chip. You can check the EID information in the following ways. If you cannot view the EID information, it means your phone does not support this feature.

1. Go to Settings > Network & internet > SIM card > Switch SIM type > Select eSIM.

                     
2. Go to Settings > System > About phone > Status > EID.

          

 

How to Add an eSIM?

You can download multiple eSIM cards, and the maximum number of eSIM cards depends on the capacity of your phone's eSIM chip. If you exceed the limit, your phone will prompt that it cannot add more eSIM cards. You can delete any eSIM cards you no longer need to free up space.

1. Make sure you are connected to a Wi-Fi network or have mobile data turned on, and choose to use data services from SIM 1.           
2. Go to Settings > Network & internet > SIM card > Switch SIM type > Select eSIM.           
    *The system will remind you that switching to an eSIM card will disable the physical card in the SIM 2 slot.

          

3. Tap Manage eSIM  > Add eSIM > Set up an eSIM.

        

4. You can add an eSIM using one of the following methods:           
    ● Scan the QR code provided by your carrier.

    

    ● Manually enter the activation code provided by your carrier: Tap Enter activation code > Enter activation code.

      

 

How to Enable an eSIM？
