Set up NumberSync for Android wearables

Learn how to set up NumberSync so you can phone or text with an Android smartwatch.

Choose your messaging app

If you don’t already have an AT&T Cloud inbox, we’ll create one for you as part of the NumberSync^SM setup. The inbox syncs messages between your smartphone and smartwatch.

For the best experience, choose AT&T Messages Backup & Sync as the default messaging app on your smartphone.

Good to know: Make sure you set up AT&T Messages Backup & Sync (cloud inbox) for your smartphone number, not your smartwatch number.

download and install it. The app can also be used on non-Samsung smartphones running Android^® 5.0 and up.

LG wearables: From your phone, download and install the Android Wear app. The app is compatible with smartphones running Android 4.3 and up.
