why my iPhone 4s doesn't have Siri?

Siri has to be turned on. Go under Settings > General > Siri and turn the feature on. There are many, many, many other threads like this, but I hope this helps!

Siri must be turned on under Settings, General, Siri. Also, you need to be able to connect to the internet to use Siri.

To find SIRI you hold down the HOME button for 3 or 4 seconds and the little Siri mic will pop up and beep, waiting for your question.

you have to turn it on. goto settings, then click general, then click siri, then switch on and choose whatever preferences you want.

I think you need a 3g or wifi connection for it to work, too

What do you do if Siri is not in the settings?

I have the same situation.. Siri is not in the settings, anyone know why? Iphone 4s

I think you have to be in one of the supported countries.

I have the same issue (no Siri in the settings), but it worked for one day (and disappeared then) and it works on all other Iphone 4S around me (we are all in the same network).

contatc Apple asap.. they'll solve it for you..

I contaced Apple & they didn't solve it. The told me to do a few quite time consuming things. I will report tomorrow.

This thread talks about the same problem as well. Im also experiencing the issue where Siri seems to have simply vanished from my settings altogether, yet remains present in the location settings. If you read the thread someone talks about speaking with apple and being told to do a factory restore and then of course restore the phones information. After doing this I still have no Siri, just the silly voice command after holding down the home button for way longer than with Siri. Screenshots are in thread as well.

I HAVE FOUND THE RESOLUTION TO MY PROBLEM!! WOOHOO! DID IT MYSELF TOO 😎

This is if SIRI is NOT showing in your Settings, General as mine wasn't....

Right, got to SETTINGS, RESTRICTIONS, I found SIRI was turned off. Turned on and SIRI re-appeared in Settings, General!

on my settings it is not there!!

in my restrictions it asks for a passcode? i dont recall putting a passcode on there.. any help as to how i can figure it out or bypass it with out doin a whole restore phone as new? thanks
