How do I activate Siri on my I pad

Which iPad do you have? Siri does not work on iPad 1 or 2

Original iPad and iPad 2 do not have Siri and never will.

You go under settings, sir I and turn it on.

Setup Siri (for iPad 3 and above)

1. Settings>General>Siri>On

2. Language>English

3. My Info>Use default

5. Settings>Privacy>Location Service>Siri>On

The chart above will tell. The model number is on the back of the device, or in settings, general, about on the iPad.
