Here is a real case
from an Android customer
who solved a carrier lock issue
during eSIM installation.

If your phone is locked
to a specific carrier,
an eSIM from another carrier
cannot be installed.

However, if there are no issues
such as unpaid device payments
or contract restrictions,
your carrier may be able to unlock the phone.

① Add eSIM

② Check the carrier lock message

③ Contact your current carrier

④ Reinstall the eSIM after unlocking

⑤ Installation completed successfully ✅

If you see a lock message, don’t worry.

Contact your current carrier right away.

✈️ Installing your eSIM
before traveling to Korea
can make your trip much easier.
