We're using our Visible data service with our main TV, Dish Hopper w/Sling, two FireTVsticks, two laptops, two cell phones, and two tablets. Our Visible SIM is in a Novatel Verizon 7730L Jetpack that supports fifteen connected devices and is connected to one of two MIMO antenna sets. So far in our travels up and down the east coast and currently in Florida, we haven't found any place where we didn't have at least some service. Sometimes it's been marginal for streaming in the weaker signal areas not surprisingly. We do have an alternate service for those times though. Connecting to our directional MIMO antenna pair and peaking the signal helps quite a bit. We've used over 150 GB a month on a number of occasions with no complaints from Visible.
We've been in a Visible "Party Pay" party almost since they introduced the feature, and have never paid more than $25/mo. since joining. Early on we lost a couple of party members, but they were quickly replaced within hours. I can't speak to the Visible customer service since I've never needed it. All in all we've been very pleased with our Visible service and have no intentions of dropping it any time soon.
