said by JohannBacker:Strange. The 2014 MJ+ is supposed to be able to be used with or WITHOUT a computer. Went through the 4 Steps indicated inside the front flap cover. Obtained a # 574-307-XXXX. Removed the Ethernet Cord from the Internet Modem an MJ+. No Dial Tone & a recorded message: "Error 1, check your internet connection or contact customer service."
It is physically a bit larger than my cellphone, therefore it should be able to "magically send and receive calls over the airwaves".
Without a computer is a lot different then without an ethernet connection.
