Can You Keep Your Number With an eSIM? Yes—Here's How

A travel eSIM does not replace your number. Learn how to keep calls and texts while using eSIM data.
One of the biggest eSIM advantages: you keep your primary number active while a travel eSIM handles data. This is called a dual SIM setup.
How it works
Your phone runs two lines at once — your home SIM (physical or eSIM) for calls/texts, and your travel eSIM for data. You choose which line does what.
Recommended settings
- Set the travel eSIM as the default for mobile data.
- Keep your home line for calls and SMS (for banking codes, etc.).
- Turn off data roaming on the home line to avoid charges.
Why it matters
You will still receive two-factor authentication texts and important calls, without paying roaming data prices.
