Overview
- Reports first surfaced in mid-August from Galaxy owners who moved to new phones and used Samsung Smart Switch and then found RCS would not enable or send messages.
- Affected users commonly see error code 3100 in Google Messages, which indicates the app cannot connect to RCS services on the device.
- Google’s official troubleshooting asks users to update Messages, turn RCS off, clear Carrier Services data, restart the phone, and re-enable RCS, but this has fixed the problem for only some people.
- Community workarounds have had mixed results; many users report success by turning off RCS, connecting to a VPN (some cited a Paris endpoint), and re-enabling RCS, while others required account resets or factory restores.
- RCS is Google’s richer, encrypted alternative to SMS, the issue affects people switching devices or carriers, and Google says it is coordinating with carrier partners to resolve cases that stem from number-porting or server connections.
