Sim Lock Warner will keep you informed when you phone requires the PIN code to unlock your SIM. With this application you will not miss any call or message anymore just because your phone has reboot silently.
This application shows a notification when you PIN code is required (ringtone and/or vibration each minute) but remains silent when you are in airplane mode.
Note : this may take a little time between PIN request and notification.
This app is really free : no ads, no payment.
* When you give only 1 or 2 or 3 stars, please add a comment and tell me what's wrong ! otherwise, I can't make it better :-/
