Hey there Billmisretired,
We understand you're experiencing an issue with your iPhone 11 Pro Max making emergency calls, and we'd like to share a resource that can help.
Check it out here: Use Emergency SOS on your iPhone
Specifically, take a look at the section below:
"Here's how to make the call on iPhone 8 or later:
- Press and hold the side button and one of the Volume buttons until the Emergency SOS slider appears.
- Drag the Emergency SOS slider to call emergency services. If you continue to hold down the side button and Volume button, instead of dragging the slider, a countdown begins and an alert sounds. If you hold down the buttons until the countdown ends, your iPhone automatically calls emergency services."
Since this occurs while riding your bike, it may be that the phone holder is pressing the side button and one of the Volume buttons, causing this to occur. If you'd like to disable this feature, check out the "Turn off Auto Call" section.
Take care!
