Ldr reply timings?

A guy I'm seeing for about 4 months has developed this habit of replying 24 hours later, sometimes it takes him 36 hours or 2 days to respond. It's a long distance relationship and we only have calls once or 2x a week.

Texting is the only way to things alive and I have brought it up a few times, he doesn't seem to want to change.

Is this normal?
