I have a Sony Ericsson Xperia Play running 2.3.4. Not rooted.
I have a few questions:
What if someone changes the sim card, and I try to send a SMS command. What would happen? Would the phone block/reject it. If yes, how can I get my phone when there is going to be no SIM card inside it? (Assuming that the person stealing it throws my sim card away).
Hi,
you receive an SMS notification to your friend’s number with the new SIM card number. Therefore you send the command to the number currently active on the device.

Oh… That’s a good feature. No wonder this is a good free app
Glad you like it
