Any tips on long distance relationships as a teen?

Me and my boyfriend are in an LDR(long distance relationship) and we’re 30 hours away driving distance, he is a trans guy but hasn’t told his parents since they are very religious and against it, we don’t get to call often since his parents don’t like him talking to people online, we have been together for 6 months and everything is going great! But we would like some advice on how to stay more connected and feel more like we’re in a relationship.
