Is my 2007 Ford Focus SE able to pair with my phone?

I have a phone button. It is the only button that relates to any sort of phone pairing. I don't even have an buttons on my steering wheel besides my cruise control. When I press the phone button, it says 'no phone'. But I can't seem to find any way to pair my phone. Is my car even able to pair with my phone? If not, then why does my car have a button that says that?

You need to read the owners manual for the pairing procedure IF it has Bluetooth.
If no Bluetooth then it is the type where you need to insert a sim card.

The 2007 Focus did not have Bluetooth, so you wouldn't be able to pair a phone. Normally the "no phone" message means that the car doesn't have Sync and you can't pair a phone with it.
