Not true. SMSCON doesn't rely on sms'es solely - actually, it can (aj\use every possible way of communication. I won't list full set of features here, leaving it as exercise for interested - preferably, to be done before commenting

Of course, if thief remove battery and put device in locker at the ocean's floor for infinity, you're done for it. But prey or any other form of payware service isn't any better in this case.

Still, we have confirmed case, where device was retrieved *months* after getting stolen - when new "owner" started using it. + few other cases with shorter timespan, including ones where victim actually got nice face-front photos of thief thanks to SMSCON

Generally, if one compare feature set, it's prey that look rather obsolete here.
