User ID tips

Update the wireless phone number linked to your AT&T user ID

For AndroidTM tablets and Connected Car, use the same ID and password for your smartphone number to set up and use AT&T NumberSync®. This ensures calls sent to and from a synced device are linked to the correct AT&T smartphone number.

Sync a device to an AT&T phone number on a different account

If your watch is on a different AT&T account than your smartphone, just use the user ID and password for the smartphone account to sync them.
