I was curious if numbersync will always be a perpetual problem child. Galaxy watch 4 to note 9. Initial integration problems, then on and off functionality for 3 years. More unsolicited disconnects, factory reset. Multiple e sim tries. Current error code 146.
If numbersync does not work reliably, then there is really no reason for a data plan on the device.
Will a mobile radio equipped watch contact 911 in the event of an emergency with no data plan?
