Twilio

Programmable communications platform. Phone numbers, SMS, voice—all via API.

Under the Hood

HighLevel and many other platforms run on Twilio infrastructure. Understanding Twilio helps when debugging HighLevel phone issues.

Direct Use Cases

• Custom applications that need calling/texting
• Building integrations via Connectors and Integrations
• More control than LC Phone at the cost of more complexity

Pricing

Pay per use. Can be cheaper than LC Phone at high volume, more expensive at low volume. Do the math for your situation.

10DLC Registration

Twilio handles A2P 10DLC registration, but the process involves multiple review layers that can slow down approvals. If you're having trouble getting campaigns approved through HighLevel's Twilio integration, SignalHouse offers a faster alternative with direct DCA relationships and built-in compliance tools.
