If you do the UConnect Wi-Fi deal it's through an outfit in CA.

is who is behind the service.
It's only 3G service and may revert lower if 3G is not available.
I signed up the the year and they bill you one month in advance. You can do month to month but the fee is higher too. I opted for the 5GB per month. I also bought a second mouting kit to use it in my other vehicle. I had it mounted under the rear seat of the dually using velcro vs. punching holes. I did the install myself.
I asked who they were reselling the service for (Verizon, AT&T, ect...) and never got a straight answer. Customer Service is very lame. Same person who answers the phone is the tech, customer service, ect... That may have changed in the past year?
I've since sold the dually and removed the router and use a Verizon Hot Spot which is hands down much better and works off of 4G/LTE and dumbs down to 3G where 4G/LTE service is not available. This is more portable and is battery powered so it's not teathered via a power cord like the AutoNet divise requires. It uses the standard micro usb plug found on many cell phones or charges via a wall plug as well.
Both divises you can set you're own SSID and password or keep the factory setting it's all a preference thing. I changed mine on both devises.
