Is guy I’m dating lying about top secret job?

Dating a guy and he told me he’s been in a different country for work. It’s early days in our relationship so I don’t know much besides it’s tech related and he gets sent on random trips every once in a while. He sent me a photo of him a couple days ago and when I saved it to my camera roll the geo tag was his hometown…at his condo…down to the street.

When I confronted him he said because of security and privacy reasons he has his vpn or something with his phone (I’m still confused on what exactly he was trying to explain) has his location set to his house but he is indeed still on this work trip abroad.

Does this makes sense? Is this a thing? I asked for a picture of him in the abroad country or a return flight with his info since he’s “coming home” soon. But there’s a time difference so he may be sleeping if he’s actually there but I am completely spiraling.
