Anyone had issues where a T-Mobile sign in session expires or something like that and I have to re-authenticate? Using my number, it tells me my number is already used. I sometimes punch in a relative's number to get back on but I've heard rumors of some sort of verification coming soon to prevent too many people from getting free WiFi by just using a friend's phone #?

Kinda annoyed this happens, but if I were to guess it's probably related to the randomized MAC address feature in most modern smartphones. I'm thinking my phone decided to switch it up sometime in flight and as a result the plane thinks my phone is now a new device. Just curious if anyone's run into this.

Phone in question is Pixel 9 Pro XL on Android 15.
