A: After unlocking, potentially yes, but you need to manually set the APN to vzwinternet and pray that Verizon doesn't reject the IMEI (they often whitelist only their own devices).
Unlike the locked ISP versions (AT&T, Bell, etc.), this unit accepts SIM cards from T-Mobile, Verizon, Google Fi, or any international carrier. I swapped SIMs in 30 seconds—no unlock codes, no ADB hacks. It pulls APN settings automatically 90% of the time. nokia fastmile 5g gateway 31 unlock
