There have been times when you forgot your phone at home, but needed to make a call - like ordering a pizza. Next time, use number sharing. With this feature, your phone and smartwatch can share the same phone number. You'll be able to make and take calls, get app notifications, and more, right on your watch.
Does a smart watch need its own phone number?
The watch gets its own phone number. When your phone is nearby, calls and texts from the watch will go through your phone and carry your regular number. When you want to step away, you can still have calls, texts and other notifications forwarded to the watch.Feb 20, 2015
Can you use two sims with same number?
Both SIM cards need to have unique numbers so it is NOT possible to have dual sim cards with the same number. This is because your number is linked to one unique SIM card and cannot be divided at the moment.
