I have an old Optimus One (LG-P500h-V20a) that I would like to put some games on and give to a child. However, I can't figure out a way to block calls to 911. Even with the SIM card removed and the phone set to airplane mode, it's still possible to access the emergency dialer from the lock screen and call 911. Other numbers (ex: 999) connect to 911 too, which I was very surprised to learn
Is there any way I can be absolutely certain the old phone can't call 911?
