My wife and I did 3.5 years of long distance relationship from 2008-2011. Skype was invaluable to us since we were able to talk to each other almost every day and see each other via video. Obviously if you have an iPhone you could substitute this with FaceTime or the equivalent to a different Phone OS.
Communication is key. I think as long as you both exercise good communication it'll help. Plus now with things like SnapChat and Instagram Stories, you can give sneak peeks into your day for your significant other. Make it fun.
