Install your eSIM before your trip while connected to Wi-Fi. Then turn on the eSIM data line after you arrive at your destination.

How to Label Your eSIM on iPhone

After installation, your iPhone may ask you to label your new eSIM line. This helps you easily tell the difference between your main SIM and your travel eSIM.

You can label it as:

Travel Business Secondary Data

For international travel, using a label like Travel or Travel Data is usually the clearest option.

How to Set Your eSIM for Mobile Data

Once your eSIM is installed, you need to choose which line your iPhone uses for mobile data.

Set eSIM as Data Line

Open Settings

Tap Cellular Data
Select your travel eSIM
Turn on Data Roaming for the travel eSIM if required

If you want to avoid roaming charges from your home carrier, make sure your physical SIM is not selected for mobile data while abroad.

Should I Turn On Data Roaming for eSIM?

Many travel eSIM plans require data roaming to be turned on for the eSIM line. This allows your eSIM to connect to supported local networks in your destination.

Important: Turn on data roaming only for your travel eSIM. Keep data roaming off for your home SIM if you want to avoid unexpected carrier charges.
