What SM2.IO is

SM2.IO brings customer conversations and related tools for small businesses into a shared inbox. It supports SMS and MMS, website chat, phone calls, email, WhatsApp Business, Apple Messages for Business, Facebook Messenger, Instagram, X DMs, and Yelp business messages. Its phone system includes VoIP, extensions, ring groups, IVR menus, routing, voicemail, and call transfers, accessible through a browser softphone, mobile dialer, or SIP desk phone. Recorded calls can be transcribed, summarized, and sentiment-scored; call intelligence is included in Pro and offered as a Premium add-on. Flow Builder creates per-contact automations with triggers, messages, waits, conditions, AI steps, and integration actions, with a simulator. The service lists Android, iOS, web, and API access. A free trial uses a real account and phone numbers, requires no card up front, and converts to a monthly subscription when it ends.
