Can I connect any smart watch to my phone?

That depends on the make and model of the watch and whether or not the manufacturer has made it compatible with iPhones. I suggest you review the documentation that came with the watch or consult the manufacturer's website.

You start by reading the instructions for your particular smartwatch. The manufacturer's website is a good place to start.

Consult the instructions for the watch. Also, check the manufacturer's website.
