I've been using Millenicom for a few years. In NY and northern Michigan. I first had the Novate 720 USB stick and Cradle Point router. When 4GLTE became available in the area of central NY - I switched to the MiFi. No 4GLTE in northern Michigan. The MiFi works great - with 4GLTE in NY and 1X or 3G in northern Michigan (Rogers City and Posen areas).
But yeah, the price went up. Also they are now discontinuing all client-based email support unless we pay extra. Still seems the be the best deal around for what we want.
