SMS
SMS (Short Message Service) is the conventional text messaging service standard. As a basic communication method, it is widely used for enterprise messaging fallback and user outreach.
Timeline (last 90 days)
iMessage is an encrypted communication protocol between Apple devices that transmits over the network and supports rich features such as read receipts and typing indicators; SMS is traditional telecom text messaging, which is cross-platform but limited in features and billed per message.
Tend's core positioning is a personal AI agent that requires no standalone app installation and is used via iMessage/SMS text messages.
Carriers have strict review requirements for A2P (application-to-person) SMS, so if Tend pushes messages proactively at scale, it will need to deal with anti-spam policies and rate limits.
Blooio connects CRMs, support teams or AI agents through a unified API, and also supports RCS, SMS and WhatsApp.
RCS (Rich Communication Services) is an upgraded version of the traditional SMS protocol, supporting features such as read receipts, typing status, high-definition images, and group chats, and is currently being promoted by Google Messages as the default messaging protocol.
Interaction methods available on feature phones include SMS, USSD, voice calls, and minimal menu interfaces.
The SMS protocol itself does not provide end-to-end encryption, which contrasts with the encryption mechanisms of WhatsApp or iMessage.
The advantage of SMS as a carrier for AI Agents lies in its being a cross-platform universal protocol that does not depend on a specific operating system ecosystem and has broad coverage.
Data from SMS channels passes through carrier networks, third-party messaging platforms (such as SMS gateway providers like Twilio), and the servers of AI service providers, forming multiple potential data nodes.
The SMS channel provides AI developers with a low-friction distribution path that bypasses the App Store and reaches users directly.
