SimplyRCS is a US RCS business messaging platform built by Signalmash. It handles brand registration, 10DLC, carrier vetting and RCS sender verification, and every message carries an SMS or MMS version for phones without RCS. An AI assistant builds bots from plain-English descriptions and picks from the replies you wrote when customers type.
The software has no platform fee. SMS and RCS Rich messages cost $0.0039 each, MMS and RCS Rich Media $0.0150, and a 24-hour RCS conversation $0.05, inbound and outbound. A local number is $0.50 a month. RCS sender setup is a one-time $250, and carrier, TCR and Aegis fees are passed through at cost (for example $200 a year for Aegis review and $500 once for T-Mobile activation). AI credit plans start at $20 a month. Premium support is $250 a month.
SimplyRCS has no iMessage. Both offer RCS with SMS fallback and state SOC 2 Type II. SimplyRCS bills per message plus carrier fees, while Linq charges a flat monthly fee from $260 on Pro with no per-message fees and also sends iMessage.
