How to Enable Business SMS for a Phone Number


If your account has been Business SMS enabled, you will be able to activate this feature and link a phone number number to your extension. 

Begin the subscription process by sending an SMS message to the phone number with the text ‘subscribe’ (without the quotes) in the message body.

  • If you own the phone number, then you will be subscribed, although the provisioning process may take up to an hour..
  • If the phone number is assigned to a different user (like an auto-attendant or another person), then an activation code will be sent to the email address of the other user.  You must send another message to the phone number with the text ‘subscribe [activation code]’



The SMS subscription process can take up to an hour. If you are still not receiving SMS messages after one hour, do the following:

  1. From any cell phone, send the word ‘ping’ (without the quotes) to your phone number number.  If your phone number was properly subscribed you will receive a response that the message was received.  If you don’t receive a response, please follow the instructions to subscribe.
  2. If you are subscribed but still do not receive SMS messages, try to re-subscribe by sending the word ‘unsubscribe’ (without the quotes) to your phone number.   Afterwards, subscribe again by following the instructions to subscribe
