Is my boyfriend being shady?

My boyfriend went out and then he called me while I was working my phone died I turned it on and when I could a couple hours later I texted him it didn’t deliver for about 4 mins. Then it delivered. So I called him and it rang once and went to voicemail. When I FaceTimed it rang all the way. So an hour later the cal went through? This is iPhone to iPhone. Is it shady behavior?
