Apple Watch SE family standalone disconnects from cellular after leaving wifi. Only reconnects with restart

I have 2 kids with Apple Watch SE, standalone with a cellular plan. They both have identical wearables plans from t-mobile.

My sons watch works just fine.

My daughters watch will disconnect itself from cellular whenever it leaves wifi. The cellular data menu states ‘not connected’

The only way to reconnect is to turn the watch on and off (cycling data or airplane doesn’t do anything) and then it works. Until the next time she enters and leaves Wi-Fi.


It’s not a problem with signal since my son, on the same plan, doesn’t have this issue. All software is up to date.


The point of the watch is to be able to reach her when she is away from the home. Currently this is a total

fail.


Anyone have ideas?

The first (and simplest) thing to try if something isn’t working right is to restart your Apple Watch and its paired iPhone. If necessary (device not responding), try a forced restart. Both methods can be found here:

If that doesn't help, the next steps would be to unpair and pair your watch again and restore from the backup just created. This should result in no loss of data. It deletes all temp and corrupted files and re-indexes the file system.
