A:Answer I believe you can use any carrier because it's not carrier based. Also, it's not even phone brand based either. Thus, you can use any carrier & many different versions of iPhones & Android based phones! Though, if you use a Samsung phone, it'll be so super-duper easy to set up!
My wife loves her new watch!
There is a little funny business with the step counter though. We exchanged it and the new one has the same funny business, so, I guess it's just the way it is.
Despite the funny business with the step counter, my wife loves this watch so much, she is happy to keep it! If she's happy, I'm happy too!
Hope this helps!
