How iMessage works with dual SIM
If you use both:

Your iPhone simply uses whichever connection provides internet.
Typical setup abroad:

iMessage uses the data connection automatically.

However, keeping your main SIM active is recommended for verification purposes.
What happens if iMessage stops working after installing eSIM?
Sometimes after changing network settings, iMessage may temporarily deactivate.
Fix:
