Default G2 Verizon Mobile Hotspot doesn't work without verizon SIM

Hi,
I can't use feature "Mobile Hotspot"
It shows error "A Verizon SIM card is not detected. Mobile Hotspot need Verizon SIM card in order to work"

I currently use this unlocked phone in Thailand
(voice call, 3G data work fine)
Can anybody help?

Thank you
