Comms Comms vs Twilio · October 2026

Start texting customers today.

With Comms you can start texting on iMessage the day you sign up, from a shared test line or your own dedicated number. SMS follows carrier registration rules, and RCS needs an eligible line and carrier enablement. There's no setup fee, just one flat monthly price with your team inbox and AI agents built in.

Your first text, two ways.

To send RCS for Business through Twilio, your brand has to clear three separate reviews and pay third-party onboarding fees, with no guarantee of approval. On Comms you sign up and start texting on iMessage.

Twilio's US RCS guidelines list each review stage and say the fees don't guarantee approval. Twilio's onboarding docs say to allow four to six weeks or longer; OneSignal reported 8–16 weeks in 2025.

On iPhone, Comms texts arrive as iMessage.

Your messages land in the same blue thread your customers use with friends and family, and their replies come straight back to your team or your AI agent.

RCS onboarding fees are set by third parties and shown in the Twilio Console; amounts vary. RCS approval times are from Twilio's RCS onboarding docs and OneSignal's 2025 reporting. Comms delivers over iMessage, RCS and SMS from a phone number, and is distinct from Apple Messages for Business. Channel availability depends on the recipient's device and carrier. AI usage is billed separately from messaging plans.
