Google Messages RCS functionality is currently experiencing widespread connectivity failures, particularly affecting users of recent Samsung devices such as the Galaxy Z Fold 8 and Galaxy S26 Ultra. The issue predominantly surfaces during device setup or when migrating to new hardware, often resulting in a 3100 error code that prevents the activation of encryption and read receipts. While the exact scope remains unclear, Reddit users have identified a workaround involving the temporary use of a Virtual Private Network. By disabling RCS, connecting to a VPN server—specifically in Paris, though other regions reportedly work—and re-enabling the service, many users successfully restored functionality. Google’s official support team recommends an alternative troubleshooting sequence: updating the Google Messages application, disabling RCS, clearing data for Carrier Services, restarting the device, and finally reactivating the service. These steps aim to resolve the persistent connection errors disrupting standard messaging capabilities on affected Android smartphones.
