Do I need 10DLC Campaign Registration to send/receive SMS on Zoom Phone Unlimited?

Hi everyone,

I recently set up my Zoom Phone Unlimited plan (Basic) last week. In my Zoom desktop and mobile apps, I can see the SMS/Text tab option available.

However, before sending any outbound texts to customers, I want to clarify the setup process. Can I directly start sending and receiving SMS to US/Canada customer numbers right away through the app, or is registering a 10DLC (TCR) SMS campaign mandatory first?

If 10DLC registration is required for business texting on Zoom Phone, what is the current approval timeline, and will outbound texting be blocked until it is approved?

Thanks in advance for your guidance!
