The mobile phone card is locked, and the mobile phone has no signal. What if I need SMS verification code?

If the SIM card is inserted into the mobile phone to prompt the SIM card lock, it may be caused by the SIM card lock set in the previous SIM card binding. It is recommended that you insert the previous SIM card and unlock it. SIM card lock has no initial password. If you forget the password, please contact the service center designated by Samsung to unlock it.
