I have bought a new ipad 2 3G and at the present time I am using it without SIM card. I have managed to make it work barely. I can navigate the web, read emails and download apps, but I cannot use iMessages or Facetime. The device will not appear on Find my device either.
iCloud.com says NO DEVICE. I have followed all instructions to associate my device with my Apple ID. I have indeed registered it manually on https://register.apple.com.... but the device is not showing associated with my AppleID even when I click to see my AppleID data.
What am I mssing? THanks.
