If you are using a smartphone, chances are you will want the highest security to protect it since smartphones don’t come cheap. Fortunately, there is a way to protect your device and your SIM card from being potentially misused if it gets stolen. Smartphones can use a software called Phone Guardian to remotely lock and unlock the phone just by sending an SMS. Sounds simple and easy, isn’t it? Read more about this software and how it works in many ways to help protect your phone against unauthorised use.
Phone Guardian helps to secure your mobile against theft in the following ways:
Send an SMS with a specific code and your chosen password (preset beforehand when you install the software) to fully lock or unlock your phone. This will definitely frustrate the culprits as there is no way they are able to make use of your device once it is locked. They can’t even attempt to sell it off to make a profit as no one will be a willing buyer of a non-functioning phone!
Send an SMS with a code and password to turn on or off a siren or alarm. This will probably be a good shock to the culprits when the siren is unexpectedly turned on! It may even alert people around the culprits that they have stolen a phone.
You can also set an auto lock function without sending an SMS. This auto lock will work upon an insertion of a different SIM card into the phone.
You can also set the siren or alarm to go off automatically when the phone is being locked. Setting this function to auto mode seems useful and saves you some work in the event that your phone does get stolen.
There are more functions on how to lock your phone in different ways. You can read more about the Phone Guardian software at this site for more information. On this site, you can also check the compatibility of this software for many smartphone models.
Using this software may not prevent the theft of your phone, but at least it will render your device useless to those who stole it and you will have peace of mind that you are not going to be charged a huge phone bill for calls you did not make.

It does a lot more than just unauthorized SIM detetection. I bought it for my Blackberry Curve and it allows you to send SMS messages to the phone to wipe data, get location, lock it and trigger an alarm. The SIM replacment also triggers data backup, so my contacts are sent to another phone automatically.
Good tip this…
Thanks for sharing the info, Nate! I like the backup function. If only this could be used for normal phones too!
