I thought that since the gear s2 was a standalone watch (it doesn't have to be paired to a phone), it would be very easy for me to leave my phone at home when making a quick trip to the store, or if i'm going out for a run. I thought I would still get all of my calls and texts and even be able to use a few apps. This is only partially true. Yes, technically, you can use it without your phone nearby. But it isn't near as seamless or as easy as I thought it would be. First, you have to enable call forwarding via the Gear app on your phone. This takes a few seconds since it calls Verizon to tell it to forward your calls. Now, if you get a call, it must first go to your phone. Your phone has to ring multiple times before it will direct it to the watch. Before the watch picks up, most people will just hang up since they think you are not answering. Should you decide not to answer or are unable to answer the call after it has been directed to your watch, the voicemail is left on your watch's number rather than your phone number. Meaning, the voicemail will not show up nor can you check it on your phone. Texting works ok, but Samsung will try to force you to use their sms app on your phone as the default, which I do not like. I use Google Messenger. Every time I open the messages app on my watch, I am greeted with a message saying that text messaging is unavailable because Samsung's app is not my default. If you close this message you can still send and receive text messages, but when I open the messages app on the watch, I can only see my sent messages. It does not show any messages from the person I am talking to. 99.9% of the apps on my gear s2 watch are unavailable when not paired with my phone. When I get back to my phone, I have to remember to turn call forwarding back off, otherwise it will drain the battery on my watch much faster. In the end, it's almost easier to just take my phone with me instead of the hassle to use my watch as a standalone. The watch seems much more like a "companion" to my phone, rather than a standalone device that allows me to leave my phone at home.
AT&T offers a NumberSync app which allows multiple devices to share the same number. I really wish Verizon would release something similar. I think that would make everything much more seamless.
