*For local network plans, please keep Data Roaming turned Off.

3. Set eSIM as Cellular Data

Tap Cellular Data, then select your eSIM as the active data line.

*Make sure "Allow Cellular Data Switching" is turned Off to avoid unexpected roaming charges.

Tap your Primary line and turn Data Roaming to Off.

5. Check Default Voice Line

Ensure your Default Voice Line is still set to Primary.

6. Confirm Activation

If all settings are configured as above, your eSIM is now successfully activated.
