Is it possible to use the same phone number for Apple Watch on AT&T?

Pairing you cellular Apple Watch to an AT&T iPhone and then activating the Apple Watch cellular radio should only cost $10 added to your iPhone cellular bill.

Your Apple Watch will get the same phone number as your iPhone.

NOTE: If you always have your iPhone with you, then you can use a less expensive GPS only Apple Watch, and it will do everything the cellular model will do, only using your nearby iPhone's cellular radio, plus no $10/month cellular fee.

Things I do with my GPS Only Series 4 Apple Watch:

• It tells time, date, day of the week

• Every iPhone alarm, appears on my wrist, where you can acknowledge it, dismiss it, etc…

• I like the iPhone 3rd party “Alarmed” app (http://yoctoville.com), for my alarms

• Ring.com door bell can display a static image on the Apple Watch

• Weather (this gets used a lot)

• MyRadar 3rd party app will display radar image

• MyRadar and WeatherBug 3rd party apps will send you weather alerts

• Make/Receive phone calls

• Make/Receive FaceTime audio calls

• Use Walkie-Talkie to other Apple Watches anywhere on the planet

• Silence phone ringing by pressing the digital crown (great for SPAM calls)

• Send & receive iMessages

• Send & receive SMS TEXT

• Say “Hey Siri, 14 and a half minute timer”

• Say “Hey Siri, remind me when I get home to do xyz”

• Say “Hey Siri, message my wife/husband/Susan/George/etc…”

• Say “Hey Siri, start Outdoor Walk”

• Say “Hey Siri, end workout”

• Say “Hey Siri, find my iPhone”

• Say “Hey Siri, flashlight”

• Use a 3rd party garage door opener app and device (such as MyQ)

• You can check your calendar

• Read your email

• If you need to take an iPhone picture where you cannot see the screen, use Apple Watch Camera app as a view finder/shutter release

• 3rd party Ocean’s Tide app for beach visits

• Hand washing reminder and timer

• Unlock your Mac (I do this several times a day)

• Unlock your iPhone when you are wearing a mask

• Track your exercise and physical activities

Since my Wife got her Apple Watch, we have been able to reliably iMessage each other, as she never keeps here iPhone on her person.

If my Apple Watch was lost, stolen, or broken, I would order a replacement as fast as possible, as I would miss it so much.
