How can I avoid accidental international roaming charges?

✅ Set Up Your SIMs Correctly

- Set your physical SIM (domestic) as [Primary]

- Set your eSIM plan as [Secondary] during installation

This ensures your device won’t switch back to the domestic SIM for data without your knowledge.

Apple

1. Go to [Settings] > [Cellular/Mobile Service]

2. Tap [Cellular Data/Mobile Data]

3. Toggle off [Allow Cellular Data Switching]

Samsung

1. Go to [Settings] > [Connections] > [SIM manager]

2. Toggle off [Data switching]

You can also contact your domestic carrier to block international roaming on your physical SIM entirely.
