I had one of the verizon pre-paid jetpacks that did this (4510L)... ended up just swapping it out for another unit/simcard.
They decided it could either be the sim or the unit but since it was a prepaid they just replaced them both. I still think it could have been an error in their provisioning but they didn't bother to (or couldn't) re-build the account so I will never know.
Since you are still under warranty I would go that route, have em swap it out at the store (both unit and sim card to cover all bases)
