Happy Friday, magenta1453055 !
I'm sorry it has taken us a couple of days to get back to you. You will need to get a hotspot device that uses one of our SIM cards. You can take a look at the devices we offer here. As far as the plan goes, do you have T-Mobile voice services with us? If so, you'll get a pretty steep discount on the mobile internet line. You can take a look at what our T-Mobile ONE plan includes along with the plans here.
After taking a look at the two links above, please let me know if you have any questions.
Just checking in here to see how things are going Let us know if you need any further assistance.
