Receive calls and messages on Apple Watch with multiple data plans

Receiving calls and messages on your Apple Watch will depend on whether your iPhone and Apple Watch GPS + Cellular are within range.

Apple Watch and iPhone connected

When your Apple Watch and iPhone are connected, you can receive calls and messages from both plans right on your Apple Watch. You will also see an icon indicating the cellular plan you are using.

The “P”icon indicates the primary SIM; the “S”icon indicates an additional SIM card. Also, in this scenario, your Apple Watch will respond in the same way.
