Random texts on watch NOT MINE !!

any idea how I could have texted someone with actually texting them and only on my watch!

I saw in my watch that a messaged a “massage parlour” which set up a date and time for an appointment. This is real scary as there was multiple texts to different parlours on this same day I’m wondering if I should report it to the police or not but I think this is result of a hacker or was someone else accidentally sending messages and the carrier used my watches number. I do have my watxh and phone synced but it was not on my phone so I hadn’t noticed these texts till months after.

But I’m just scared for another situation similar to this. I’m not sure what’s to gain but the texts seem to be from a spoofed or like fake number so maybe it’s a scam I’m not sure any insight is appreciated!!
