So I may be being stupid, but i recently added the Galaxy watch to my EE plan. I was told that the watch would have the same number as my phone and that if I chose to leave my phone at home then I could and use my watch for calls and texts instead. However it seems the watch will only work if it is in close proximity to my phone. I don't understand why it won't do what I was told it would do.
they is two models one for Bluetooth connection and one for LTE and Bluetooth connection, if bought the LTE model you can add a mobile plan to it via the galaxy Wear app, that allows you to make calls and texts from the watch.
