¿Why sms and cell calls doesn't work on mac?

I downloaded iOS 8.1 and have yosemite OS installed in my mac. i have tried to use the calls and sms feature but none of this works.

In the calls when i try to call someone a message pops up saying that i must have an iphone and a mac with the same iCloud and FaceTime account. But the devices that i'm using do have the same accounts and still does't work!!

I have noticed that my phone number does't appear with a check and that in the FaceTime of my iphone a message down the switch to activates says "waiting for activation", but i can still make normal FaceTime calls. does this have something to do? how do i fix it? i have tried to reset the settings but everything is still the same.

In the sms feature the same message "waiting for activation" is down the iMessage title, i can send iMessages but when i try to activate sms a message says "enter the code displayed on the other device" but the code in my mac never shows up. What's the problem here? i have also tried to reset the settings and rebooting the devices but it's the same. Does this has to do with my phone number being unchecked? the problem is that i can't check it, the opti

Please help me.
