If your eSIM supports data-only, you can still use another line for voice and SMS.

Please check your eSIM's Additional Information details to learn your plan type. You can learn how to do it by checking: "Can I make phone calls or send SMS with my eSIM?".

In order to use your primary line for voice and text while you enjoy your eSIM for data, you need to enable the primary line and set it up as your Default Voice line.

The data roaming may also need to be enabled depending on the requirement of your home provider. This may incur roaming charges, so we highly encourage you to consult your home provider to learn about the charges before proceeding.
