Simple Salon allows you to have your SMS messages send to your clients with your salon name displayed instead of the mobile number it comes from.
There's a catch though—if you do this, then your clients can no longer reply to the SMS. Due to the number being overridden with a word, the clients can't reply to the text message.
Therefore, if you have 2 Way SMS happening, where your clients reply Yes to confirm their appointments, you will no longer have that functionality.
If you want to set it up, go to Admin > SMS & Email, then in the SMS Account Setup section enter the salon name into the Dedicated Number section, and click Save.
