You can check this by contacting your carrier before travel.
When Does My Mexico eSIM Activate?
Most travel eSIMs activate when they connect to a supported network in the destination country.

- Go to your phone settings.

This does not mean you are using expensive roaming from your home carrier. It simply allows the travel eSIM to connect to its partner network in Mexico.
