Help to unlock LG G Pad 7.0 vk410 Verizon

Got a tablet VK410. Trying to catch network with non-Verizon GSM sim-card, but says "no network found". Manual network search is not present in settings. Device specs says it supports GSM.
So seems to be network locked. Will not ask unlock code.

Tried to connect as V410, but no luck. VK410 currently not supported
