"Great News, your line can now get more data for less every month."

Switching Jetpacks?
Do not go through Verizon to upgrade or replace a hotspot/Jetpack device if you are on the (now retired) pUDP Jetpack plan.
We have seen several reports of people losing their retired pUDP Jetpack line and having it replaced with a currently available plan.
Purchase any new equipment you want 3rd party, and swap your pUDP SIM card into the device. This is known to be working with out issues at present time.
