RCS vs SMS: What Changes for Your Texts and Codes

RCS is the newer form of texting, with typing indicators, read receipts and Wi-Fi messaging. SMS is the basic text. Verification codes still arrive by SMS.

Side by side

RCS on your phone

• Android: Google Messages › Settings › RCS chats.
• iPhone: recent iOS versions support RCS with Android phones where carriers allow it; look in Messages settings.

When RCS causes trouble

If verification for chat features gets stuck, or messages to a friend who changed phones go missing, turning RCS off and on usually helps. See Google verifying your number for chat features.

RCS and privacy

Chats between two phones using Google Messages with RCS can be end-to-end encrypted, shown by a lock icon. SMS is not encrypted. Verification codes sent by SMS are protected by expiring quickly, not by encryption.
