Dual SIM Setup: Home + Travel eSIM Together

Dual SIM lets your phone use two lines at once — ideal for travel. Here is how to set it up cleanly.

Assign roles

• Home line: calls and texts (keeps your number reachable).
• Travel eSIM: mobile data.

Key settings

Set your travel eSIM as the default for data. Disable data roaming on the home line so it never uses expensive roaming data. On iPhone, also turn off "Allow Cellular Data Switching".

Everyday use

You will still get calls and verification texts on your home number, while browsing, maps, and apps run on the affordable eSIM data.
