Protect your Android Investment with TheftAlarm
A simple and yet effective anti-theft program has been created by XDA member BigWheeelS. In order to protect your latest Android investment and find the bad soul who decided that your phone was worth stealing, you need to have apps like this one. The app will recognize the SIM card being used in the device as it will look at the IMSI number and match it against whatever you program it with. If this SIM card does not match, it will send an SMS with information about the new SIM trying to use the device to a pre-configured number in the program’s settings.
The app is light weight and easy to set up. Give it a go and make sure you leave feedback for the dev.
The program is designed to help you to find phone if it is stolen or lost.
This works like this:
In the program settings you add allowed SIM card and phone numbers to send SMS messages.
After the boot program reads the IMSI number of the current SIM card.
If the IMSI is in a list of allowed, it displays a notification that the SIM is checked and the program ends.
If the current IMSI is not in the list of allowed, then program send an SMS messages to configured in the settings telephone numbers.
If for some reason the message is not sent (there is no network signal, enabled airplane mode, etc.), the program attempts to send it again after 10 seconds and it will be repeated before the SMS is not sent.
Thus in case of missing device can learn the phone number, which is using your phone.
