The SMS text messaging protocol has been in place for 20 years, and it does have some pretty significant limits. ShowMojo is engineered to work with those limits.

We try to give our customers as many characters as we can within a text message. But we also work to avoid the incomprehensible messages that can stack up on less-than-premium phones when the phone service cuts up or misorders multiple text messages. It's a delicate balance.

One additional message you should not have to worry about is CodeBox instructions for self-showings. Whenever it distributes an access code, ShowMojo includes a link to photo instruction for the CodeBox.
