This is a bit of a tedious way , to get someone's Phone identity.It is far easier , to make some kind of app (game /movie watching /or whatever) with some malicious software in it.
Those who install the app , will then have the required information from their Phone , sent to the maker /owner of the app.He /she can then take over your Phone , have access to your Phone book , your contacts list and see /read your text messages.
He /she can then call numbers in your Phone book or send them certain text messages.It will be very hard to explain to those , who will get these messages or Phone calls ,that it was not you who actually did send these calls /texts.
In that situation you will need to reset your Phone to Original manufacturer settings , and buy a new sim card.But you should be aware that the hacker still has the IMEI number of your Phone.
I'm not sure though , if he/she can use this IMEI number to take over your Phone again with a new sim card.
Another method the hacker uses is to let you Phone a certain number.When the connection is established , the server then pushes the malicious software to your Phone.This can take some minutes and all this time they will put you on hold - with a message that the connection is being checked !!!
In this situation they also take over your Phone - they can then switch on your camera / or make video recordings /
When your Phone is hacked check for these signs :
1 - is your Phone set on silent mode (but you did not do that)
2 - have things changed to your photo gallery
3 - is your battery time reduced , even though you don't use the Phone so much
4 - is your Phone switched to fly mode suddenly (and you did not do that)
It is Obvious that the hacker will put your Phone to silent or fly mode , because he doesn't want you to hear that your Phone is making a Phone call (or the number dialling tones)
Or it is making a photo etc....
So , be aware and use your common sense .....
