With tethering, I'm not sure I want a SIM card in my laptop! If nothing else, AT&T will charge me extra for that (I'm already paying extra per month for my Apple Watch to have LTE connectivity). Whilst I don't take my phone running because I can use my Watch for music and can make calls on it while out, I don't think I'd ever be somewhere with my laptop and no phone.
