After Verizon did the resync it worked for a little while. I found that didn't really fix it. It's stopped working many times since then. I've found that I have to power the phone off and then on again. When I do that the hotspot works for a while after that. It's not location dependent at all and once the phone reboots it works perfect. Motorola is replacing my device due to a chip in the frame from the factory. Will see if the new phone has the issue. It works fine with AT&T SIM so I think it's more likely it's a Verizon issue.
