Automatically send SMS when changing SIM card of smart phone.

Software introduction

Automatic keyboard locking function. When this function is turned on, the keyboard will automatically lock after we don't use it for a period of time. In this way, our mobile phones can't reach the number we don't want to dial or start some unnecessary functions!

Mobile phone security function. When opening this function, users need to set their familiar mobile phone numbers. When the user's mobile phone is lost and another SIM card is inserted into your mobile phone, your mobile phone will automatically send your customized information to your designated mobile phone number every time it is restarted. So you can know who is using your mobile phone (you can find the other party's number by SMS).
