What is RCS messaging?

RCS (Rich Communication Services) is the modern successor to SMS - supporting read receipts, typing indicators, high-quality media, and richer interactions over mobile networks.

RCS upgrades traditional texting with features people expect from chat apps: better images and video, group features, read receipts, and interactive elements, all in the default messaging app on supported phones.

For AI assistants, RCS - alongside iMessage, Telegram, and WhatsApp - is one of the channels that lets an assistant live in your texts rather than requiring a separate app.

how this works in folk

Folk meets you in the messaging you already use - iMessage, Telegram, and WhatsApp - so there's no new app to download. Texting an assistant in your default messages is the whole idea.

frequently asked

Is RCS the same as iMessage?

No. iMessage is Apple's proprietary system; RCS is a cross-platform standard increasingly supported across iOS and Android. Both enable richer texting than plain SMS.

Do I need RCS to use folk?

No. Folk works over iMessage, Telegram, and WhatsApp - you just text it like a friend.
