Can I pair a standalone Apple watch to an iPhone without a cellular plan?

My iPhone service is through Xfinity. I would like to get a standalone Apple watch for my 9yr old daughter (who does not have a cellphone), but Xfinity doesn't offer a standalone watch option. If I pair an Apple watch on their network, it will be connected to my phone number and she will receive all of my texts, etc., which I do NOT want.


T-Mobile DOES offer a standalone option, so I could get a standalone data plan for her there, but it still has to be paired to an iPhone (which again Xfinity will not allow). My question is.. can I pair an Apple watch to a phone that doesn't have a cellular plan? I've received conflicting information about whether this is possible. Since the actual data plan is specific to the watch and provided by T-Mobile, I can see how it might be a possibility. I'd use an old iPhone 11, but it would just sit at my house plugged in and on a Wifi network. We aren't ready to get her a phone, but do really like the idea of her having a watch. I am hoping someone has experience with this scenario and can provide some feedback. Thanks!


**And just to confirm, I can't switch my phone to T-Mobile for another year because we have a year left on our contract.

iPhone 11

In terms of the hardware you need, two quick notes:

  1. You need an Apple Watch Series 4 or later with cellular,* or Apple Watch SE with cellular, with watchOS 7 or later.
  2. A cellular plan isn't required to set up an Apple Watch for a family member, but is necessary for some features. See Set up Apple Watch for a family member - Apple Support.


Now if you DO want to get the T-Mobile standalone option, you don't need to have the Watch connect on the same network as the iPhone you're setting it up with:

If your carrier doesn't support Family Setup, or you'd like to use a different carrier, select Not Now.* You can choose an alternative carrier from this list of supported carriers and contact them directly to set up your cellular plan.

Plus, since all Apple Watches are unlocked, you can most definitely add a T-Mobile plan to the Watch.


So you can either:

  1. Use your iPhone to set up the Apple Watch without cellular.
  2. Use your iPhone to set up the Apple Watch with T-Mobile service. In this case, you might want to look into the $5/mo 500MB Digits Standalone Plan with Auto-Pay from T-Mobile (I have the same as a customer). You will have to contact T-Force (T-Mobile support on Facebook Messenger or X, best support option), chat online, or visit a store to activate this plan, as it isn't available on their website.


Hope this helps and let us know if you still face issues setting this up!

I have an Apple watch with GPS and a Cellular plan from T-Mobile. I have been paying for a cellular plan for several years under the assumption that in the event my phone was ever lost, I could use my Apple Watch as a "back up" to make and receive calls or send text messages.

That is not the case.

If I turn off my phone or the battery dies, my watch is basically useless. I can't make or receive a call or send a text message.

Therefore, help me understand why I am paying for a plan if I need the phone turned on and in the same vicinity as the watch for it to work.

Hi Bob, Thanks for the response.

I’m even more confused by your response.

If I don’t need Family Setup to have a separate number for the Apple Watch for my child, then what do I need?

I miss the part about your child. You only need a carrier that supports the Apple Watch Family Plan for your child’s Apple Watch.


Your iPhone carrier does not need to support the Apple Watch Family Plan.


So you can use Xfinity, and your child can use:
