More from Phone Link (different sending problem)

Open one failed message on the phone, tap Check options, and choose Send as text (SMS/MMS); if that works, the failure is the Google Messages RCS handoff rather than the PC-to-phone connection.

Phone Link successfully transferred the messages to the phone—the screenshot shows them inside Google Messages—but Google Messages did not complete sending them. This exact “Not Sent. Check options” symptom has been reported when a Phone Link message is handed to Google Messages and then fails during the RCS/chat send path.^1^

Fix the failed messages

1. On the Android phone, tap Check options below one failed message.
2. Select Send as text (SMS/MMS) if offered.
3. If only Resend as RCS appears, try it once while the phone has a working Wi-Fi or mobile-data connection.
4. Send a new message directly from Google Messages on the phone to the same group:
   • If that also fails, troubleshoot Google Messages, RCS, or the mobile carrier rather than Phone Link.^2^
   • If direct sending works but messages initiated through Phone Link fail, use SMS/MMS for Phone Link messages or use Google Messages for Web when RCS is required.

Phone Link officially supports SMS and MMS. RCS through Phone Link is limited to select Samsung phones and requires Samsung Messages to be the default messaging app; Google Messages does not meet that requirement.^3^ ^4^

If every Phone Link message now fails

1. Update both linking apps
   • Android: Link to Windows → Settings → Check for Updates.
   • PC: Phone Link → Settings → About → Updates.^5^
2. Check Phone Link’s message setting
   • PC: Phone Link → Settings → Features → Messages.
   • Ensure Allow this app to show text messages from my phone is enabled. Enable the MMS options as well if the group is sent as MMS.^6^
3. Test a plain one-to-one text
   • Send a short text without a link or attachment through Phone Link.
   • If that succeeds while this three-person conversation fails, the issue is confined to the group’s RCS/MMS route.
4. Temporarily test without RCS
   • In Google Messages, open profile picture → Messages settings → RCS chats (sometimes called Chat features) and turn RCS off.
   • Send another message from Phone Link. Similar Phone Link/Google Messages synchronization problems have been resolved by disabling RCS.^7^
   • If this resolves it, leave RCS off when using Phone Link, or turn it back on and use Google Messages’ own web interface for RCS conversations.
