I have the ZTE Quartz smartwatch with it's own service line. I have a question: is it possible to call my own smartphone from my smartwatch? I have tried this and the calls ring once and then go to voicemail but when calling other numbers, the calls will go through. Is there an explanation for this and how do I change it? Suppose a family member has my phone and I have to call them from my watch, how can I get through?
When you call your own number it'll take you to voicemail always. Doesn't matter the carrier. If you have it set up with digits your watch will have the same behavior. Turn off Digits and let the watch use its own internal number instead of the shared number.
