Whats a good excuse to call my boyfriend?

He has no phone and uses his parents phone (seperated) and since summer started (around 2 weeks) we haven't talked. I want to call him but when i try his mom sends excuses like "he is mad at fortnite" and dumb stuff like that. I really want to talk to him and I miss him but I don't want to seem possessive by calling him every other day for no apparent reason. (and please give me real excuses, not break up or don't make excuses"
