Once you have to enabled text message reminders for LifeCycles your company will be assigned a static phone number from which your text messages will be delivered. To view this number go to Settings > Your Company Profile
How am I assigned a phone number?
We automatically assign you a phone number based on the location of your business. Local phone numbers are not always available but we will request one if it is. If a local number is not available when your request is made, we will request another number for the city you live in, then the county, then the state, then the neighboring state (for users who live on a border of two states). We will accept the phone number that geographically is closest to your business's address.
