We get a number of questions about the SMS functionality and we'll address a number of them here.
SMS is charged at $0.09 per 160 character message sent. Generally, a staff member with 5 shifts is a week will have their entire roster on one message. If shifts are split each day, it is likely that the roster would push into a second message
Staff currently cannot reply to an SMS roster and have that come through to a manager as a response
Managers or Admins who publish rosters are not able to add additional information to the SMS roster
Zenshifts does not have a shift confirmation process through SMS at this stage
