How to Add or Remove Apple Watch NumberSync on AT&T Business
This guide shows how to add or remove Apple Watch NumberSync on an AT&T business account. If your Apple Watch line is already active, you can connect it to your iPhone for calling, texting, and data use even when your iPhone is not nearby.
Need Apple Watch activation first? If you bought your Apple Watch from Apple, keep in mind that Apple cannot activate devices on AT&T business accounts. Please contact Curtis Matthews to activate the watch line on your AT&T business account before setting up NumberSync.
Important Before You Upgrade Your Apple Watch
If you are moving from an old Apple Watch to a new one, remove NumberSync from the old watch first. After that, go through the Add NumberSync steps on the new Apple Watch.
