As of right now, all of the Twilio numbers in your account will be grouped and used in rotation together. We are adding a feature that will allow you to separate them into groups (markets) and use them separately in campaigns as you do with your current Sherpa numbers. However, if you currently have a mix of area codes in your Twilio account, you will need to deactivate the numbers (in your Sherpa Number Manager Twilio tab) that you don't want to use at that time until the new feature is released.

You may also continue to use your current Sherpa numbers in some campaigns, and use Twilios in others.
