Can you still use Visible with Mofi 4500 for unlimited hotspot?

Hello, I saw a video about this setup for remote internet and purchased the Mofi 4500. It works great with my US cellular but I'm wondering if anyone is currently using a Visible sim card with their Mofi to boost the signal and if the hotspot data is unlimited? And is it just the $25 per month plan that allows you to do this? 

Thank you,
