Hey mendinfences, and thanks for posting.
I think you're right about needing some configuration help with this one. With T-Mobile hotspot devices, there's an Admin page that'll let you change the settings. Take a look at our Network & APN: Alcatel LINKZONE page for example. I know it's not the exact same device as the Jetpak but it has a screenshot of the settings we have on our supported devices. You may be able to enter them on the the admin screen for your Jetpak.
Images on that link are not displaying. Is it me only or did anyone else notice this?
Hey there vronp and thanks for stopping by.
Sorry to hear they're giving you trouble. I double checked those images in a few browsers and the are showing up. If you're on a computer, can you try clearing out your browser history and cache then try again?
