Text Message Forwarding not appearing on iPhone 5

Question

I'm trying to set up Text Message Forwarding between my iPhone 5 8.1.2 and iMac 10.9.5.  For some reason it is not showing up in my Settings > Messages options on my iPhone.
I am signed in with my Apple ID on both devices.  I can receive iMessages on my iMac but cannot receive SMS messages.  In the Settings > Messages > Send & Receive options, I have both my phone number and email checked.  I have searched high and low for answers but have not been able to find a solution.
Anyone have any ideas?

Hi jello32,
Happy Holidays!  The resource below will explain how to setup the Continuity feature and troubleshoot issues with SMS and Text Message Forwarding between your iPhone and iMac.
Connect your iPhone, iPad, iPod touch, and Mac using Continuity - Apple Support
http://support.apple.com/en-us/HT6337
To use Continuity for SMS and MMS with your iPhone and your Mac, iPad or iPod touch
SMS requires an iPhone with iOS 8.1 and an activated carrier plan.
Your iPhone, iPad, and iPod touch need to use iOS 8.1, and your Mac needs to use OS X Yosemite.
Sign in to iMessage on your iPhone, your other iOS devices, and your Mac using the same Apple ID.
On your iPhone:
Go to Settings > Messages > Send & Receive > You Can Be Reached By, and add a check to both your phone number and email address.
Go to Messages > Text Message Forwarding, and enable the device(s) you would like to forward messages to.
Your Mac, iPad, or iPod touch will display a code. Enter this code on your iPhone to verify the SMS feature.

If a Continuity feature like Handoff, phone calls, Instant Hotspot, or SMS messages isn't working the way you'd expect, make sure your devices meet the requirements. Then check your settings.
Check System Requirements
Make sure your iPhone, iPad, iPod touch, or Mac meet the system requirements for Continuity, and for the specific features you want to use.
Check your settings
Check the following settings on your iPhone, iPad, or iPod touch:
Go to Settings > Wi-Fi and turn on Wi-Fi if necessary.
Make sure your iOS devices are connected to the same Wi-Fi network by going to Settings > Wi-Fi and comparing the name of the network each is on.
Go to Settings > Bluetooth and turn on Bluetooth if necessary.
Go to Settings > General > Handoff & Suggested Apps and make sure Handoff is on.
Go to Settings > Phone. If you see Wi-Fi Calling, turn it off.
Check the following settings on your Mac:
Go to the Wi-Fi icon at the top of your screen and turn on Wi-Fi if necessary.
Make sure your Mac and iOS devices are connected to the same Wi-Fi network. Go to Settings > Wi-Fi on your iOS device and compare the name of the network with the Wi-Fi network on your Mac.
Go to the Bluetooth icon at the top of your screen and turn on Bluetooth if necessary.
In System Preferences > General, select “Allow Handoff between this Mac and your iCloud devices.” If you don't see this setting, your Mac may not support Handoff.
Open the FaceTime app, go to FaceTime > Preferences and turn on “iPhone Cellular Calls.”
Go to System Preferences, and sign out and then sign in again to your iCloud account.
If your device can't access the Internet using Instant Hotspot
If you don't see the option to use your iPhone or cellular-enabled iPad as an available Wi-Fi network, make sure that your cellular provider has provisioned Personal Hotspot on your device.
I hope this information helps ....
