Frequently asked questions

What is Signal House?

Signal House is a complete communications platform (CPaaS) that provides SMS, MMS, Voice, and messaging APIs for businesses and platforms. We're a Messaging and Voice Aggregation platform specializing in A2P (Application-to-Person) 10DLC messaging with industry-leading deliverability rates above 95%. We focus on fast, dependable message and voice delivery with enterprise-grade reliability.

What makes Signal House different from other CPaaS providers?

Signal House delivers enterprise-grade communication infrastructure with transparent pricing, exceptional support, and faster implementation. Unlike providers that bundle unnecessary features and services, we focus on doing the essential communication services extremely well – SMS, MMS, Voice, and APIs that just work.

How is Signal House different from Twilio?

Signal House is a complete Twilio alternative offering SMS, MMS, and Voice services with up to 80% cost savings, faster and more helpful support, quicker 10DLC campaign approvals, and an intuitive user experience. Compared to Twilio, we provide clearer pricing, faster setup, no bundled products or upsells, and superior deliverability without the complexity and overhead.

How much does Signal House cost compared to Twilio?

Signal House costs up to 80% less than Twilio while providing comparable or superior service. Customers have reported saving $25,000 to $40,000 per month after switching from Twilio to Signal House, with the added benefits of better support, faster 10DLC campaign approvals, and improved message deliverability.

What communication services does Signal House support?

Signal House supports SMS, MMS (images, videos, and GIFs), Group SMS, and Voice across 10DLC, toll-free, and short code numbers, plus messaging APIs for integrating with your existing systems. RCS, alphanumeric sender IDs, Apple Business, and WhatsApp are on our roadmap.

What is 10DLC messaging and why does it matter?

10DLC (10 Digit Long Code) messaging refers to using standard 10-digit phone numbers for application-to-person business messaging. It matters because carriers now require proper registration for business messaging, and 10DLC provides local, recognizable numbers that build trust with recipients while ensuring high deliverability rates and compliance with carrier requirements.

Hear what our clients have to say

“Utilizing Signal House for our messaging was a turning point for our company. Prior to moving to SH, we experienced poor support, messages getting filtered (up to 60%!), and paying a premium. We are saving over $40,000 per month with Signal House.”
