I'd like to use Apple Watch Series 4 as a standalone device to make phone calls.

On an Apple Watch Series 4 Cellular, can I make a phone call via cellular network without my iPhone, which I'd like to leave at home, connected to it via Bluetooth or WiFi?

And, can I additionally make phone calls via a Bluetooth headset which connects directly to the Apple Watch 4?

An Apple Watch Series 4 (along with Series 3) with support for Cellular can make a phone call without an iPhone but will need to be paired with it. Apple Watch Cellular comes with a build-in eSIM. It needs to be paired with the SIM card in your iPhone.

Apple Watch Series 4 is typically expected to support all the phone call/cellular features of Series 3.

Note: Having an iPhone is a prerequisite for using an(any) Apple Watch. Thus, it's not possible to use an Apple Watch (any generation), without owning an iPhone.

  • Does it mean that once paired, I can leave my iPhone home and make phone calls with the Watch 4 on the go? Sep 12, 2018 at 18:11
  • @LarsBlumberg Yes. That's true even for Apple Watch Series 3.

  • Ah, that's great. If you could highlight that in your answer, I could accept it. Sep 12, 2018 at 18:13
  • Right now your answer reads as if it's not possible to make calls when away from the phone. Sep 12, 2018 at 18:14

    Most (if not all) carriers charge extra for cellular watch. In the US it’s 10/month + tax.
