What's the benefit of getting one with a SIM rather then just a Bluetooth connection to your mobile?
It can be used to access data services independently of your phone.
Pretty much what naja states. Smart watches are a bit of a fad purchase and often provide very little. They are basically a digital watch with notifications from your phone and for full functionality they need to be connected to your phone. With an inbuilt sim they can act as a more independent device. You can use them as a phone on your wrist as they tend to come with speakers and mics. For me, I want a smartwatch to actually be smart. I want video calling, decent messaging, GPS and mapping capability etc etc. The problem is that to do all that you need bigger screens, bigger processors, and more importantly a bigger battery.
Fitness and activity trackers are interesting as they serve a purpose. For sports and the gym they are good at what they do. I can see the appeal of them but due to them becoming a trendy item to have they kinda evolved into something else. 'Smart' watches were born out of that trend and its brought watches back in fashion but they are still nothing more than activity trackers with a watch face.
What I want is something like a
Nubia Alpha. It's still very early days for that tech and I think Nubia just missed the mark but are certainly on the right path to a true 'smart watch' The
Tag Heuer Connected dropped in my inbox the other day and for the first time I really wanted a smart watch. Purely for the cool factor. Its overpriced and lacking in quite a few features and its also a bit behind on tech. I just bought my Mum a
Garmin Approach S62 and for some crazy reason she wants a fitbit/smartwatch. Being more a tech guy I went all out and bought her something with added cool factor.
Even with the approach, you can easily download an app form your phone and do exactly the same for a fraction of the price. Quite a few people at work are wearing smart watches with Samsungs and Apple Watches being the most popular.
