A:AnswerThe watchband is easily replaceable and there are so many different and inexpensive watchbands (silicon, metal, nylon, etc.). Takes me less than five minutes to replace the watchband because it has a small clip portion that releases the watch band pin without needing any special tools.
A:AnswerConnectivity is strong. I'm not sure exactly how far you're getting from your phone, but it works all over the house while attached to mine.
I believe the rep at Best Buy said it was possible to get it added to a cell plan so you can have coverage everywhere regardless of where your phone is, but don't hold me to that.
A:AnswerYes, you do get notification from What's App. However, I havent been able to download the app on the phone. So, you can intiate sending messages. For now, I read what's app message and can respond but I am unable to initiate the text.
