Need to add or remove Apple Watch NumberSync on an AT&T business account? This guide covers setup, removal, upgrades, and what to know before changing your watch.

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. NumberSync lets your Apple Watch use your iPhone's wireless number for calls and texts. With an active cellular Apple Watch line, your watch can also use AT&T cellular service 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.

Apple Watch NumberSync Requirements

For cellular service when your iPhone is not nearby, you need a cellular-capable Apple Watch with an active AT&T wireless plan. Your Apple Watch should also be paired with your iPhone through the Watch app.

How Much Does an Apple Watch Line Cost?

The standard AT&T Business Unlimited for Apple Wearable plan is $10 per month, plus applicable taxes and fees. Your actual wearable cost may be lower depending on your smartphone plan. AT&T Business Unlimited Premium 3.0 provides 50% off the monthly access charge for a qualifying wearable, while Ultimate 3.0 includes access for one wearable and one tablet plan per qualifying phone line, subject to plan-group device limits.

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 setup steps on the new Apple Watch.

How to Add NumberSync for Apple Watch on AT&T Business

Open the Watch app on your iPhone.
Tap Cellular.
Tap Set Up Cellular.
Follow the AT&T prompts to add NumberSync. Sign in with your AT&T user ID and password if prompted, then confirm your emergency address and accept any required terms.
Wait for confirmation that cellular service and NumberSync are active.

Once setup is complete, your Apple Watch can use your iPhone's wireless number for calls and texts. With an active cellular watch plan, it can also connect to the AT&T network when your iPhone is not nearby.
