When I had my s3 this wasn't an issue but on my s4 I don't have Internet while on the phone and yes I have 4G where I live

That's because the s3 is able to use 3G and calling at the same time. The S4 doesn't have the hardware for it. Since you say you have 4G in your area, when you make a call are you connected to 4G or 3G?
