My old Keurig coffee maker died. I order this new one and was surprised to learn you are expected to have a cell (I-phone or whatever) to run it. No instructions I could find on how to brew a cup of coffee without a phone. We don't have cell service here hence no cell or I-Phone! I winged it and finally got it to brew without a phone although it keeps telling me I'm not hooked up yet. I do like the fact that it actually measures the coffee sizes correctly (the older coffee makers didn't do so good at that). That's really important for brewing flavored coffees, cocoa, etc. Just want you to know that not everybody on this planet has cell service but we still enjoy good coffee!
