Are there ANY options for setting up text notifications instead of email?

Question:

My client wants notifications to come to his phone via text, not an e-mail, but I don’t see ANY options for that ANYWHERE. Is this something that slipped through the cracks during development on wix’s part?

What have you already tried:
[went to notification settings, form settings, don’t see an option to receive SMS notifications]
