When near iPhone, Ultra 2 watch cellular only connecting when bluetooth is off

So funny that the same thing happened to me. I was on the phone with T-Mobile for hours trying to solve this.

So I believe I was in your shoes, I wanted to put my iPhone on airplane mode with Wi-Fi and Bluetooth off so it wouldn’t consume any battery since I was Out on the street. However, the watch cannot get cellular or cellular data at all. It looks like having your phone nearby, jams the Apple one. And I wasn’t happy with it, because ideally I wanted to use my Apple Watch for cellular stuff while my phone was on airplane mode and not consuming battery as much.

Anyway, the way around this is to completely turn off your phone if you’re going to have it with you while you plan to use your Apple ultra watch completely cellular to make calls and browse emails, etc. It is so weird. And of course, leaving your house with your phone off or on and taking the Apple Watch with you will also work as normal with its cellular capabilities. However, I am curious now to try putting my phone on airplane mode with Wi-Fi and Bluetooth off, and leaving the house with my ultra watch to see if cellular works. If this is the case, then this confirms that having your watch in proximity to your iPhone will still pair it even if Bluetooth is off on your iPhone.
