A:AnswerI activated this smart watch with Verizon, same carrier as my cellphone, using number share so that if someone calls my cellphone, it will ring on my watch even if I don't have my cellphone with me. I couldn't activate it online because of problems with their system (thought it was an Apple watch) and I had to call customer support, but they finally got it all set up.
