Google Voice updates point to upcoming RCS messaging support

An analysis of version 2026.11.01.10 of the Google Voice app has uncovered multiple clues and code strings suggesting that RCS support is finally being developed. While the service currently only supports standard SMS and MMS across all plans, strings referencing the ability to toggle RCS chats and a dedicated compose box label indicate that changes are coming. It remains unclear when RCS will officially be enabled for users, as the findings are currently limited to app code references rather than functional features. If implemented, the update would bring benefits such as end-to-end encryption, read receipts, and high-resolution media sharing to Google Voice users.
