Samsung intentionally coupled their Gear S smartwatch so tightly with their Galaxy smartphones that they officially require you to use a Samsung Galaxy smartphone to activate the Gear S smartwatch before you can use it. Not just any Android smartphone, or even any Samsung smartphone. It must be a Samsung Galaxy smartphone or phablet. So what happens if you don't own a Samsung Galaxy smartphone or phablet?

Fortunately, we have a solution, which would allow you to activate the Samsung Galaxy Gear S with any smartphone or phablet you want, even if it's the Apple iPhone. In fact, you can even activate the Gear S smartwatch to use independently of any smartphone. Best of all, the steps are very simple and does not involve the rooting of the Gear S.
