Hi Dom,
For the record, it's your carrier that charged you, not WaveSecure. In fact, it costs us to send out SMS messages.

Hi Reinhard,
With regard to the comment "Other software does this since ages", our company never claimed that we are the first implement a security service works on a system of SMS-triggered commands. We do, however, hold a patent for our solution.

As for the subscription fees, we are running a business so it is no surprise that we need a revenue model. That said, WaveSecure for Android has been free and we've been giving out lifetime subscription accounts for users who downloaded and activated it before 31 March 2010. Do let us know if you have paid for WaveSecure for Android. You might have been conned.

The point you brought up about not having internet configured is one of the main reasons why WaveSecure utilizes SMS for reliable communication. Without depending on a data plan or needing the handset to be configured for internet access, WaveSecure will send a SMS to your buddies when it detects an unknown SIM. An email will also be dispatched to you containing the number from that SIM.

The app is visible on the phone because it lets you perform features like backing up your data and restoring it.

From our experience, most people with bad intentions will remove the original SIM and insert their own SIM, rather than hard reset it. When that happens, WaveSecure will do it's work to protect the phone, data and privacy.

Thanks,
