Everything you can do with Zoom Phone texting
Zoom Phone is a phone system, but it's also a business texting tool. Here's how SMS and MMS work — from sending your first text to registration, limits, compliance, and automatic replies.
Can you send text messages from Zoom Phone?
Yes. If you have a Zoom Phone number in the US or Canada, you can send and receive SMS and MMS directly from the Zoom desktop app, the mobile app, and Zoom on the web. Texts come from your actual business number — the same one people call — and every conversation lives in your Zoom Phone SMS inbox alongside your call history.
How to send a text on Zoom Phone
- Open the Phone tab in the Zoom app and select SMS.
- Click New message, then enter a contact or phone number.
- Type your message. Attach a photo to send it as MMS if needed.
- Send. Replies appear as a threaded conversation you can pick back up any time.
SMS vs MMS vs group messaging
SMS is plain text. MMSadds media — images and other attachments. Zoom Phone also supports group messaging, so a single thread can include several participants. Longer messages are automatically split into multiple segments by the carrier, which is worth remembering if you pay per-segment on a metered arrangement.
10DLC registration (do this first)
US carriers require A2P 10DLCregistration for business texting — a one-time brand and campaign registration your Zoom administrator completes in the admin portal. Until it's approved, your outbound texts can be filtered or blocked. If your Zoom Phone texts aren't sending, unregistered or pending 10DLC is the most common cause — see Zoom Phone SMS not working for the full checklist.
10DLC is about deliverability and compliance, not an upsell. It protects your number's reputation so legitimate business texts actually reach people. Register once and it applies across your Zoom Phone SMS.
Texting limits and compliance
Carriers enforce throughput limits tied to your 10DLC campaign, and message content is subject to consumer-protection rules like the TCPA. The practical takeaways: get consent before texting customers, honor opt-outs (STOP), keep messages relevant, and text within reasonable hours. Our compliance guide walks through this in plain English.
