But it is more work than just using kingo
The TOS that you have to agree to to install Kingo states that they send no data of any kind from your PC or Your phone. So if they do send your IEMI somewhere which does not really matter anyways since your IEMI is plastered on every cell tower you have ever connected to they would be in violation of their own TOS and could be sued.
