How to get better service with virgin mobile?

So i have virgin mobile and it seriously sucks i dont wanna change carriers cause the plans are too expensive and i already bought an iphone which was like 500 bucks
the service is pretty crappy so is there a way to make it better or something i could do

please help its really annoying thanks

I would sale it and go get a bost mobile or straight talk

Stand on top of a sprint tower and maybe you will get better service. Lol virgin mobile sucks!
