Q: icloud keychain verification code text never arrives

Hello michelesapple,

Thanks for using Apple Support Communities.

From your post I understand you are unable to receive the iCloud Keychain verification code.  I'm sorry this is causing so much frustration, but it is understandable as it's a great feature to use.  To troubleshoot this specific issue where you're not receiving the SMS, please follow the steps below.

 

If you didn't receive the verification code via SMS

1. Make sure that you have a strong cellular network connection on your phone.
2. Make sure that your phone number can get SMS messages. To check, ask someone to send you a text message.
3. Make sure that the correct phone number is associated with your account:
   • On your iPhone, iPad, or iPod touch, tap Settings > iCloud > Keychain > Advanced. (In iOS 7, tap Settings > iCloud > Account > Keychain.) Make sure the phone number under Verification Number is correct. If not, enter another phone number. 
   • On your Mac, choose Apple menu > System Preferences. Click iCloud, then click Options next to Keychain. (In OS X Mavericks or earlier, click iCloud, then click Account Details.) Make sure the phone number under Verification number is correct. If not, enter another phone number.

If you can't access a device that has iCloud Keychain enabled, contact Apple Support and verify your identity to get help setting up iCloud Keychain.
