Verizon says it isn't tetherable and I believe them.
I bought the Moto W755 and it too is "not tetherable" according to Verizon. I ignored that, got the USB drivers from Motorola, installed access manager software and turned the $60 feature on for one month. Worked perfectly WHEN IT WORKED. Unfortunately I kept getting password/login errors constantly and it would not hold the connection longer than a few minutes. Returned the 755, unhitched the unlimited access feature and am now waiting for my "new in 2" which kicks in two weeks from now. Probably get an LG 9100 which definitely works. I would get the V750 in a New York minute if it were tetherable.
