Label your plans

Name your eSIM something like "Travel" so it is easy to identify. Keep your home line as "Primary".

Choose data settings

Set your travel eSIM as the default for data, and turn off "Allow Cellular Data Switching" to avoid accidental roaming on your home line.

Do this on Wi-Fi before your trip — the plan activates automatically when you arrive.
