In most cases, travelers simply use the eSIM for mobile internet while keeping their normal SIM active for calls or SMS if needed.
Can You Keep Your WhatsApp Number With eSIM?

Your WhatsApp continues working because:

- the eSIM only provides mobile data
- you are not changing your WhatsApp account itself
Most travelers continue using WhatsApp exactly as before.
