MacBook Pro: Cannot call or AirPlay via iPhone Hotspot

Subject :- Cannot make outgoing calls or AirPlay while connected to iPhone Personal Hotspot

Hi everyone,

I am having trouble getting Continuity features (specifically outgoing calls and AirPlay) to work between my MacBook Pro and iPhone.

My Hardware:

• Mac: MacBook Pro (16-inch, 2019) A2141, Core i9.

• iPhone: iPhone 13.

• OS Versions: macOS Tahoe 26.2 iPhone 26.2

The Network Setup: My MacBook Pro is connected to the internet via my iPhone's Personal Hotspot.

The Problem: Even though both devices are signed into the same Apple ID and connected (via Hotspot), I am encountering the following issues:

1. Outgoing Calls: I can successfully receive phone calls on my Mac. However, when I attempt to dial out from the Mac, I get the error message:

"Your iPhone and mac must be on the same wi-fi network"

1. AirPlay: I cannot AirPlay music from Apple Music on my iPhone to my Mac. The Mac does not appear or connect, despite "AirPlay Receiver" being turned on.

Settings Verified:

• Both devices are signed into the same iCloud / Apple ID.
• Handoff is enabled on both devices.
• FaceTime is enabled and active on the Mac and call from iphone in macos is on at FaceTime
• AirPlay Receiver is enabled on the Mac.
• Both have Bluetooth and Wi-Fi enabled.

My Question: Is it possible to make outgoing calls and use AirPlay when the "network" is just the iPhone's Personal Hotspot? Or does this feature strictly require both devices to be connected to a separate, third-party Wi-Fi router?

Any insight would be appreciated!
