DialPhone Business SMS guides

TCPA and 10DLC compliant business messaging, shared team inboxes, AI drafting, and SMS marketing patterns.

Business SMS open rates sit above 95% when the messaging is properly consented and targeted, but US carriers enforce TCPA and 10DLC registration strictly, and sending campaigns without proper registration triggers throttling or blocking. Posts in this cluster cover 10DLC campaign registration, HIPAA-safe SMS for patient communications, shared team inbox workflows, AI drafting for outbound follow-ups, and the compliance dividing line between transactional and promotional messaging.

Methodology

How we research this cluster

SMS compliance posts cite primary sources: the TCPA as interpreted by current FCC declaratory rulings, CTIA Messaging Principles and Best Practices, and individual carrier (T-Mobile, Verizon, AT&T) 10DLC policy pages. Case law (FTC consent decrees, class-action settlements) is referenced where it sets a concrete compliance standard. Every SMS post is reviewed by DialPhone compliance before publication.

Most articles in the business sms cluster get re-verified every 90 days against current vendor pricing pages, product documentation, and primary regulatory sources. Where a vendor changes pricing or feature scope between verification windows, the affected article is flagged in our editorial dashboard for immediate update. Last-modified dates on every article reflect the most recent verified-as-of date, not the original publication date. The full corrections log is summarized in the editorial standards page.

Cross-cluster reading: the business phone cluster covers fundamentals around cloud PBX migration, number porting, and AI-era voice features; the contact center cluster covers omnichannel routing, agent assist, and CCaaS evaluation; the UCaaS cluster covers platform strategy and migration playbooks; and the industry solutions cluster covers vertical-specific deployments. The communications glossary defines the terminology referenced across every cluster, and the open VoIP Pricing Research 2026 report grounds the pricing benchmarks.

Factual corrections: support@dialphone.com with the article URL and the specific claim. Errors get corrected publicly with visible last-updated dates and a brief change note in the article body where the original copy was material to the reader's decision.

FAQ: business sms

Do I need 10DLC registration to send business SMS?

Yes, for any business sending to US consumers. 10DLC (10-Digit Long Code) registration assigns your brand and messaging campaigns to the carrier network and unlocks normal throughput. Unregistered traffic is heavily throttled or blocked. Registration takes 1-4 weeks, costs a one-time $4-$50 brand fee plus per-campaign fees. See the 10DLC registration guide.

Is business SMS TCPA compliant?

TCPA compliance depends on consent, not technology. For marketing SMS you need prior express written consent. For transactional SMS (order updates, appointment confirmations) you need prior express consent. Every business SMS platform supports opt-out handling via STOP/HELP/UNSUBSCRIBE keywords, the compliance failure mode is usually at consent capture, not at send time.

Can I send HIPAA-compliant SMS?

Yes, with a BAA in place and properly configured. DialPhone signs HIPAA BAAs covering SMS on the Advanced plan and above. The platform handles encryption in transit, access controls, audit logs, and message retention per HIPAA Security Rule requirements. The responsibility stays with the covered entity to limit PHI in message body and confirm recipient identity before sending. See HIPAA texting rules.

What is the difference between SMS and MMS for business?

SMS (Short Message Service) is 160 characters of text per segment, works on every phone, carrier-grade reliability. MMS (Multimedia Messaging Service) supports images, video, and up to 1,600 characters. MMS costs 2-5x more per message and has slightly lower delivery consistency on older devices. For business, most compliance and marketing workflows use SMS; MMS is added for product images in retail and healthcare discharge instructions.
