From Frustration to Focus: How Prompt.io Found the Right Messaging Partner in SignalWire
For any company delivering communication services at scale, the reliability of your infrastructure can make—or break—your business. For Prompt.io, a turnkey text messaging platform built to help organizations connect with their customers and supporters, that reliability wasn’t always a given.
The Problem: Complexity, Cost, and Communication Breakdowns
Prompt.io’s mission is to make SMS communication easy for their clients—no developer required. But behind that simplicity lies a complex stack of tools and connectivity that has to just work. When infrastructure issues crop up, they create friction not only for the Prompt.io team, but for every organization relying on them.
Phil’s team needed a provider that offered:
Reliable message delivery
Scalable infrastructure
Transparent pricing
Responsive support
Unfortunately, those boxes weren’t being checked—until they found SignalWire.
"The biggest change since we switched to SignalWire is that I’m not pulling my hair out nearly as often."
— Phil Gordon, CEO, Prompt.io

What is RCS messaging?
Rich Communication Services (RCS) is the next generation of mobile messaging, designed to replace SMS and MMS. It supports high-quality images and video, verified sender identities, read receipts, typing indicators, and interactive elements like carousels and quick replies, all within the phone's native messaging app.
What is RCS Business Messaging (RBM)?
RCS Business Messaging (RBM) applies RCS capabilities to brand-to-consumer communication. It lets businesses message customers from a verified brand identity instead of a phone number, share rich media and documents, offer quick replies and CTAs, and handle actions like appointment confirmations and payments without the customer leaving the chat.
Is RCS replacing SMS?
RCS is positioned as the successor to SMS, but the transition is gradual. Businesses should adopt RCS where supported while keeping SMS and MMS as fallback channels for devices and networks that don't yet support it.
Does iPhone support RCS?
Yes. Apple added RCS support starting with iOS 18, with RCS Business Messaging support arriving in iOS 18.1. Combined with existing Android support, this brings RCS to the large majority of smartphones in the US.
Is RCS more effective than SMS for customer engagement?
Yes. Nearly 80% of consumers say RCS makes them more likely to engage with a brand, and RCS campaigns can achieve click-through rates up to 7x higher than SMS thanks to rich media, interactivity, and verified sender trust.
ow do businesses start sending RCS messages?
Businesses must first register an RCS agent, an approval process involving Google, aggregators, and mobile operators. From there, they can define use cases like marketing, customer service, or appointment reminders. SignalWire guides businesses through registration and campaign planning.
Which industries benefit most from RCS?
Retail, finance, and healthcare are early leaders. Retailers use RCS for in-chat purchases and product carousels, financial institutions use it for secure verified messaging and account alerts, and healthcare providers use it for appointment scheduling and reminders.
