How can I get IMEI on IOS with ionic structure

You can use the Device object from Cordova . A device object describes the hardware and software of a device. Since the "device" is assigned to the window object, it is implicitly in the global scope, so you can easily call it in your onDeviceReady function, for example:

var deviceID = device.uuid;

      

        
        
        
      

    

On iOS, no permissions are required.

It will not be possible sadly in iOS7 , Apple stopped accessing these details in iOS7, I believe.
