mag.login ka sa
www.icloud.com using your APPLE ID and password. Pwede mong ma.track ang location ng phone mo for it's last known location. If hindi pa naka.off ang phone, pwede mo track ang live location nya.
With icloud.com, pwede kayo maka.send ng message sa iphone of your alternate contact number if found, set the phone to LOST MODE para hindi magamit, set the phone to ALARM para ma.alert ang prospect buyer na nakaw ang unit.
If all hope is lost at di na talaga mababalik ang unit, you can remotely wipe clean the phone para wala ng silbi ang iphone to buyers. It will just be a iphone casing without iOS software.
If you can buy a new iphone unit, you can restore your old settings, via icloud.com
I hope that helps.
