How to get IMSI number programatically?
I need a way to verify an iPhone still have the same SIM (and it is active)
I guess the only secure way is checking the IMSI, how can I get it?
Is there another way?
Thx in advanced.
You don't - Apple does not provide a way to get any identifier unique to a device. You can detect your application, and can develop your own identifier, but that is about it.
