Unlike some of our competitors who offer so-called text messaging that makes you specify what carrier your customer's cell phone is on, all you need is your customer's cell phone number in Groomsoft. Do you know why they ask for your customer's carrier? Mostly all mobile network carriers allow you to email a phone number with a special domain name, such as 8885551212@txt.att.net. That would email the 888-555-1212 phone number on AT&T's network. Email is insecure and not always reliable!
When your customer says they didn't get that text message appointment reminder, (and you know that will happen sooner or later) you can view the delivery status of that text message. You can view the delivery status of every text message sent within Groomsoft, by simply viewing the message.
