When you upgrade from a current Advanced Messaging RCS smartphone to a new smartphone featuring Messages by Google:

• We suggest you use Samsung Smart Switch or other transferring applications to move messages from your current Samsung device to your new one if you don’t choose Copy apps & data during initial device setup. Smart Switch is in the app section in the Samsung folder.
• You can copy text, picture, multimedia, and RCS messages from your old Samsung device to your new one.
• You should know that AT&T Messages Backup & Sync (AMBS) isn’t compatible with Messages by Google.

Good to know: If you downloaded Messages by Google from Google Play Store on your previous smartphone, you may need to first de-register from Google RCS to accelerate setup with AT&T RCS Advanced Messaging on your new smartphone:

• Enter your phone number at Messages by Google’s Disable Chat page.
• Open the Messages app, go into Messages settings, then Chat features, and toggle on Enable chat features.
