Why can’t i activate facetime on the ipod touch

If the SSID is hidden, that means you don’t see the network’s name, so the only way to connect is by manually typing the SSID.

You have to select “Other” from the list of WiFi networks.

According to Apple, some of the symptoms are:

• When you are calling someone on FaceTime, the number on their screen is not your number.
• People are unable to initiate a FaceTime call with you.
• After installing a new carrier settings update, FaceTime does not activate.

How to fix:

• In Settings > Phone, turn FaceTime OFF and turn it back ON again
• Go to Settings > General > Reset > Reset all settings
• Done
