My bf hasn't contacted me from overseas yet?

My bf has gone overseas on a holiday with his family.. He left yesterday and called me a few times before he left... I checked the flight and it landed last night.. I'm a real anxious worry wart sort off person .. I have OCD as well.. I'm worried about my bf and am upset he has not contacted me yet ... I told him to MSG me when he has settled in.. He took his work phone with him so I know he has roaming.. But haven't heard from I keep thinking why doesn't he care about me or miss me... Or is he safe? Etc I really want my bf to have fun and technically it's only been 1.5 days... Do you think I should leave it?
